This is pretty darn crazy. One file runs on 6 operating systems, with GPU support.
- tfinch 3y ago
  yeah the section on how the GPU support works is wild!
  - thelastparadise 3y ago
    So if you share a binary with a friend you'd have to have them install cuda toolkit too? Seems like a dealbreaker for the whole idea.
    - brucethemoose2 3y ago
      > On Windows, that usually means you need to open up the MSVC x64 native command prompt and run llamafile there, for the first invocation, so it can build a DLL with native GPU support. After that, $CUDA_PATH/bin still usually needs to be on the $PATH so the GGML DLL can find its other CUDA dependencies. Yeah, I think the setup lost most users there. A separate model/app approach (like Koboldcpp) seems way easier TBH. Also, GPU support is assumed to be CUDA or Metal.

        I'm sure doing better by windows users is on the roadmap, exec then reexec to get into the right runtime, but it's a good first step towards making things easy.
      - jart 3y ago
        Author here. llamafile will work on stock Windows installs using CPU inference. No CUDA or MSVC or DLLs are required! The dev tools are only required to be installed, right now, if you want get faster GPU performance.
        vsnf 3y ago
        My attempt to run it with the my VS 2022 dev console and a newly downloaded CUDA installation ended in flames as the compilation stopped with "error limit reached", followed by it defaulting to a CPU run. It does run on the CPU though, so at least that's pretty cool.
        jart 3y ago
        I've received a lot of good advice today on how we can potentially improve our Nvidia story so that nvcc doesn't need to be installed. With a little bit of luck, you'll have releases soon that get your GPU support working.
        abareplace 3y ago
        The CPU usage is around 30% when idle (not handling any HTTP requests) under Windows, so you won't want to keep this app running in background. Otherwise, it's a nice try.

  Like a docker for LLMs
  - verdverm 3y ago
    I don't see why you cannot use a container for LLMs, that's how we've shipping and deploying runnable models for years
    - simonw 3y ago
      Being able to run a LLM without first installing and setting up Docker or similar feels like a big win to me. Is there an easy way to run a Docker container on macOS such that it can access the GPU?
      - verdverm 3y ago
        Not sure, I use cloud VMs for ML stuff We definitely prefer to use the same tech stack for dev and production, we already have docker (mostly migrated to nerdctl actually) Can this project do production deploys to the cloud? Is it worth adding more tech to the stack for this use-case? I often wonder how much devops gets reimplemented in more specialized fields

Extremely cool and Justine Tunney / jart does incredible portability work [0], but I'm kind of struggling with the use-cases for this one. I make a small macOS app [1] which runs llama.cpp with a SwiftUI front-end. For the first version of the app I was obsessed with the single download -> chat flow and making 0 network connections. I bundled a model with the app and you could just download, open, and start using it. Easy! But as soon as I wanted to release a UI update to my TestFlight beta testers, I was causing them to download another 3GB. All 3 users complained :). My first change after that was decoupling the default model download and the UI so that I can ship app updates that are about 5MB. It feels like someone using this tool is going to hit the same problem pretty quick when they want to get the latest llama.cpp updates (ggerganov SHIIIIPS [2]). Maybe there are cases where that doesn't matter, would love to hear where people think this could be useful.

  It’s just a zip file, updating it should be doable in place while it’s running on any non windows platform and you just need to swap that one file out you changed. When it’s running in server mode you could also possibly hot reload the executable without the user even having any downtime.
  - tbalsam 3y ago
    > in place ._. Pain.
  - csdvrx 3y ago
    You could also change you code so that when it runs, it checks as early as possible if you have a file with a well known name (say ~/.freechat.run) and then switches to reading from it instead for the assets than can change. You could have multiple updates my using say iso time and doing a sort (so that ~/.freechat.run.20231127120000 would be overriden by ~/.freechat.run.20231129160000 without making the user delete anything)

> you pass the --n-gpu-layers 35 flag (or whatever value is appropriate) to enable GPU This is a bit like specifying how large your strings will be to a C program. That was maybe accepted in the old days, but not anymore really.
- tomwojcik 3y ago
  That's not the limitation introduced in Llamafile. It's actually a feature of all gguf models. If not specified, GPU is not used at all. Optionally, you can offload some work to the GPU. This allows to run 7b models (zephyr, mistral, openhermes) on regular PCs, it just takes a bit more time to generate the response. What other API would you suggest?
  - amelius 3y ago
    This is a bit like saying if you don't specify "--dram", the data will be stored on punchcards. From the user's point of view: they just want to run the thing, and as quickly as possible. If multiple programs want to use the GPU, then the OS and/or the driver should figure it out.
    - andersa 3y ago
      They don't, though. If you try to allocate too much VRAM it will either hard fail or everything suddenly runs like garbage due to the driver constantly swapping it / using shared memory. The reason for this flag to exist in the first place is that many of the models are larger than the available VRAM on most consumer GPUs, so you have to "balance" it between running some layers on the GPU and some on the CPU. What would make sense is a default auto option that uses as much VRAM as possible, assuming the model is the only thing running on the GPU, except for the amount of VRAM already in use at the time it is started.
      - insanitybit 3y ago
        > They don't, though. If you try to allocate too much VRAM it will either hard fail or everything suddenly runs like garbage due to the driver constantly swapping it / using shared memory. What I don't understand is why it can't just check your VRAM and allocate by default. The allocation is not that dynamic AFAIK - when I run models it all happens basically upfront when the model loads. ollama even prints out how much VRAM it's allocating for model + context for each layer. But I still have to tune the layers manually, and any time I change my context size I have to retune.

I think the best way to try this out is with LLaVA, the text+image model (like GPT-4 Vision). Here are steps to do that on macOS (which should work the same on other platforms too, I haven't tried that yet though): 1. Download the 4.26GB llamafile-server-0.1-llava-v1.5-7b-q4 file from https://huggingface.co/jartine/llava-v1.5-7B-GGUF/blob/main/llamafile-server-0.1-llava-v1.5-7b-q4 https://huggingface.co/jartine/llava-v1.5-7B-GGUF/blob/main/...: wget https://huggingface.co/jartine/llava-v1.5-7B-GGUF/resolve/main/llamafile-server-0.1-llava-v1.5-7b-q4 2. Make that binary executable, by running this in a terminal: chmod 755 llamafile-server-0.1-llava-v1.5-7b-q4 3. Run your new executable, which will start a web server on port 8080: ./llamafile-server-0.1-llava-v1.5-7b-q4 4. Navigate to http://127.0.0.1:8080/ http://127.0.0.1:8080/ to upload an image and start chatting with the model about it in your browser.

        What’s the best in terms of coding assistance? What’s annoying about gpt 4 is that is seems badly nerfed in many ways. It is obviously being conditioned in its own political bias.
estebarb 3y ago
Currently which are the minimum system requirements for running these models?
- Hedepig 3y ago
  I am currently tinkering with this all, you can download a 3b parameter model and run it on your phone. Of course it isn't that great, but I had a 3b param model[1] on my potato computer (a mid ryzen cpu with onboard graphics) that does surprisingly well on benchmarks and my experience has been pretty good with it. Of course, more interesting things happen when you get to 32b and the 70b param models, which will require high end chips like 3090s.

    That's a nice model that fits comfortably on Raspberry Pi. It's also only a few days old! I've just finished cherry-picking the StableLM support from the llama.cpp project upstream that you'll need in order to run these weights using llamafile. Enjoy! https://github.com/Mozilla-Ocho/llamafile/commit/865462fc465597241da52b916c6057ad8714c361 https://github.com/Mozilla-Ocho/llamafile/commit/865462fc465...

  In my experience, if you're on a mac it's about the file size * 150% of RAM to get it working well. I had a user report running my llama.cpp app on a 2017 iMac with 8GB at ~5 tokens/second. Not sure about other platforms.
- jart 3y ago
  You need at minimum a stock operating system install of: - Linux 2.6.18+ (arm64 or amd64) i.e. any distro RHEL5 or newer - MacOS 15.6+ (arm64 or amd64, gpu only supported on arm64) - Windows 8+ (amd64) - FreeBSD 13+ (amd64, gpu should work in theory) - NetBSD 9.2+ (amd64, gpu should work in theory) - OpenBSD 7+ (amd64, no gpu support) - AMD64 microprocessors must have SSSE3. Otherwise llamafile will print an error and refuse to run. This means, if you have an Intel CPU, it needs to be Intel Core or newer (circa 2006+), and if you have an AMD CPU, then it needs to be Bulldozer or newer (circa 2011+). If you have a newer CPU with AVX or better yet AVX2, then llamafile will utilize your chipset features to go faster. No support for AVX512+ runtime dispatching yet. - ARM64 microprocessors must have ARMv8a+. This means everything from Apple Silicon to 64-bit Raspberry Pis will work, provided your weights fit into memory. I've also tested GPU works on Google Cloud Platform and Nvidia Jetson, which has a somewhat different environment. Apple Metal is obviously supported too, and is basically a sure thing so long as xcode is installed.

bjnewman85 3y ago
Justine is creating mind-blowing projects at an alarming rate.
dekhn 3y ago
I get the desire to make self-contained things, but a binary that only runs one model with one set of weights seems awfully constricting to me.
- omeze 3y ago
  Eh, this is exploring a more “static link” approach for local use and development vs the more common “dynamic link” that API providers offer. (Imperfect analogy since this is literally like a DLL but… whatever). Probably makes sense for private local apps like a PDF chatter.
- simonw 3y ago
  There's also a "llamafile" 4MB binary that can run any model (GGUF file) that you pass to it: https://simonwillison.net/2023/Nov/29/llamafile/#llamafile-trying-other-models https://simonwillison.net/2023/Nov/29/llamafile/#llamafile-t...
  - dekhn 3y ago
    Right. So if that exists, why would I want to embed my weights in the binary rather than distributing them as a side file? I assume the answers are "because Justine can" and "sometimes it's easier to distribute a single file than two".
    - simonw 3y ago
      Personally I really like the single file approach. If the weights are 4GB, and the binary code needed to actually execute them is 4.5MB, then the size of the executable part is a rounding error - I don't see any reason NOT to bundle that with the model.
      - dekhn 3y ago
        I guess in every world I've worked in, deployment involved deploying a small executable which would run millions of times on thousands of servers, each instance loading a different model (or models) over its lifetime, and the weights are stored in a large, fast filesystem with much higher aggregate bandwidth than a typical local storage device. The executable itself doesn't even contain the final model- just a description of the model which is compiled only after the executable starts (so the compilation has all the runtime info on the machine it will run on). But, I think llama plus obese binaries must be targeting a very, very different community- one that doesn't build its own binaries, runs in any number of different locations, and focuses on getting the model to run with the least friction.

> Windows also has a maximum file size limit of 2GB for executables. You need to have llamafile and your weights be separate files on the Windows platform. The 4GB .exe ran fine on my Windows 10 64-bit system.
- jart 3y ago
  You're right. The limit is 4 gibibytes. Astonishingly enough, the llava-v1.5-7b-q4-server.llamafile is 0xfe1c0ed4 bytes in size, which is just 30MB shy of that limit. https://github.com/Mozilla-Ocho/llamafile/commit/81c6ad3251f1fafd77a579d599f8646d7606df47 https://github.com/Mozilla-Ocho/llamafile/commit/81c6ad3251f...
  - throwaway743 3y ago
    Not at my windows machine to test this out right now, but wondering what you mean by having to store the weights in a separate file for wizardcoder, as a result of the 4gb executable limit. How does one go about this? Thank you!

From a technical standpoint, this project is really fascinating. I can see a lot of use cases for getting something up fast locally for an individual user. But for anyone in a production/business setting, it would be tough to see this being viable. Seems like it would be a non-starter for most medium to large companies IT teams. The great thing about a Dockerfile is that it can be inspected and the install process is relatively easy to understand.

This is not to be dismissive but there is a security risk if we keep on using the abstraction with arbitrary objects being serialized to disk and being able to trace back and see if the model file (most commonly python pickle files) aren’t tampered with .

If your AI has Python sand box and that has vulnerabilities, you can be hacked by any web page or text file.

Fantastic. For those of who who swim in the Microsoft ecosystem, and do not compile Linux apps from code, what Linux dustro would run this without fixing a huge number of dependencies? It seems like someone would have included Llama.cpp in their distro, ready-to-run. Yes, I'm an idiot.
- jart 3y ago
  llamafile runs on all Linux distros since ~2009. It doesn't have any dependencies. It'd probably even run as the init process too (if you assimilate it). The only thing it needs is the Linux 2.6.18+ kernel application binary interface. If you have an SELinux policy, then you may need to tune things, and on some distros you might have to install APE Loader for binfmt_misc, but that's about it. See the Gotchas in the README. Also goes without saying that llamafile runs on WIN32 too, if that's the world you're most comfortable with. It even runs on BSD distros and MacOS. All in a single file.

    It doesn't seem to run on NixOS, though I'm new to Nix and may be missing something. $ ./llava-v1.5-7b-q4-server.llamafile --help ./llava-v1.5-7b-q4-server.llamafile: line 60: /bin/mkdir: No such file or directory Regardless, this (and Cosmopolitan) are amazing work - thank you!
    - jart 3y ago
      The APE shell script needs to run /bin/mkdir in order to map the embedded ELF executable in memory. It should be possible for you to work around this on Linux by installing our binfmt_misc interpreter: sudo wget -O /usr/bin/ape https://cosmo.zip/pub/cosmos/bin/ape-$(uname -m).elf sudo sh -c "echo ':APE:M::MZqFpD::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register" sudo sh -c "echo ':APE-jart:M::jartsr::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register" That way the only file you'll need to whitelist with Nix is /usr/bin/ape. You could also try just vendoring the 8kb ape executable in your Nix project, and simply executing `./ape ./llamafile`.

great! worked easily on desktop Linux, first try. It appears to execute with zero network connection. I added a 1200x900 photo from a journalism project and asked "please describe this photo" .. in 4GB of RAM, it took between two and three minutes to execute with CPU-only support. The response was of mixed value. On the one hand, it described "several people appear in the distance" but no, it was brush and trees in the distance, no other people. There was a single figure of a woman walking with a phone in the foreground, which was correctly described by this model. The model did detect 'an atmosphere suggesting a natural disaster' and that is accurate. thx to Mozilla and Justin Tunney for this very easy, local experiment today!

If my reading is correct, this literally just distribute an LLM model and code, and you need to do some tasks - like building - to make it actually run, right? And for this, you need to have additional tools installed?

Wow, it has CUDA support even though it's built with Cosmopolitan? Awesome, I see Cosmopolitan just this month added some support for dynamic linking specifically to enable GPUs! This is amazing, I'm glad they found a way to do this. https://github.com/jart/cosmopolitan/commit/5e8c928f1a37349a8c72f0b6aae5e535eace3f41 https://github.com/jart/cosmopolitan/commit/5e8c928f1a37349a... I see it unfortunately requires the CUDA developer toolkit to be installed. It's totally possible to distribute CUDA apps that run without any dependencies installed other than the Nvidia driver. If they could figure that out it would be a game changer.

I like the idea of putting it in one file but not an executable file. Using CBOR (MessagePack has a 4gb bytestring limit) and providing a small utility to copy the executable portion and run it would be a win. No 4gb limit. It could use delta updates.

Small field test: I uploaded a picture of a typical small Korean Buddhist temple, with a stone pagoda in front. Anyone at all familiar with East Asian Buddhism would instantly recognize both the pagoda and the temple behind it as Korean. Llamafile: "The image features a tall, stone-like structure with many levels and carved designs on it. It is situated in front of an Asian temple building that has several windows. In the vicinity, there are two cars parked nearby – one closer to the left side of the scene and another further back towards the right edge. . ." ChatGPT4:"The photo depicts a traditional Korean stone pagoda, exhibiting a tiered tower with multiple levels, each diminishing in size as they ascend. It is an example of East Asian pagodas, which are commonly found within the precincts of Buddhist temples. . . The building is painted in vibrant colors, typical of Korean temples, with green being prominent." No comparison, alas.

  That's not a llamafile thing, that's a llava-v1.5-7b-q4 thing - you're running the LLaVA 1.5 model at a 7 billion parameter size further quantized to 4 bits (the q4). GPT4-Vision is running a MUCH larger model than the tiny 7B 4GB LLaVA file in this example. LLaVA have a 13B model available which might do better, though there's no chance it will be anywhere near as good as GPT-4 Vision. https://github.com/haotian-liu/LLaVA/blob/main/docs/MODEL_ZOO.md#llava-v15 https://github.com/haotian-liu/LLaVA/blob/main/docs/MODEL_ZO...

Does it use Metal on Mac OS (Apple Silicon)? And if not, how does it compare performance-wise against regular llama.cpp? It's not necessarily an advantage to pack everything (huge quantified 4bit? model and code) into a single file, or at least it wasn't when llama.cpp was gaining speed almost daily.
- simonw 3y ago
  It uses the GPU on my M2 Mac - I can see it making use of that in the Activity Monitor GPU panel.
  - jart 3y ago
    Correct. Apple Silicon GPU performance should be equally fast in llamafile as it is in llama.cpp. Where llamafile is currently behind is at CPU inference (only on Apple Silicon specifically) which is currently going ~22% slower compared to a native build of llama.cpp. I suspect it's due to either (1) I haven't implemented support for Apple Accelerate yet, or (2) our GCC -march=armv8a toolchain isn't as good at optimizing ggml-quant.c as Xcode clang -march=native is.

It’s intriguing to observe how this model is hallucinating. I presented it with Albert Bierstadt’s painting “In the Mountains” (https://www.wikiart.org/en/albert-bierstadt/in-the-mountains-1867 https://www.wikiart.org/en/albert-bierstadt/in-the-mountains...). To my surprise, it maintains that cows are scattered throughout the scene, despite being told otherwise. User: Llama: The image features a serene landscape with mountains in the background and a river flowing through it. A picturesque scene unfolds as two trees are visible near the water, adding to the natural beauty of the environment. In addition to these elements, there is an interesting detail: several cows can be seen standing on or around the grassy area next to the body of water. The presence of these animals creates a sense of tranquility and harmony with nature in this idyllic setting. User: There are no cows. Could it be that you've mistaken rocks for cows? Llama: No, the rocks in this image are not mistaken for cows. They can be seen near a lake with mountains in the background and trees surrounding it. The painting captures a serene landscape where nature is beautifully displayed. This picturesque scene showcases both the majestic mountain range and the tranquil body of water, creating an idyllic atmosphere that evokes feelings of peacefulness and relaxation. User: There are no cows! Llama: The image depicts a serene scene of mountains and water. A beautiful lake is surrounded by majestic snow-capped mountains, creating an idyllic landscape. In the foreground, there are trees adding to the natural beauty of the environment. A few birds can be seen flying in the sky above the lake, further enhancing the peaceful atmosphere. The presence of a boat on the water adds another element of leisure and enjoyment to this picturesque scene. Overall, it is an inviting image that showcases nature's wonders with its combination of mountains, lake, trees, birds, and boats.

Hmmm no matter what image I upload, it's somehow not seeing it. Got a chuckle out of this, though: --- User: Describe the image in the most detailed way possible Llama: The image is a close-up of an empty, dark room with no visible objects or people. It appears to be a black background photo that highlights the darkness and emptiness of the space. This could potentially represent an artistic representation or an actual setting where lighting has been used to emphasize the contrast between light and shadow. The focus on this particular area suggests that it might have some significance, whether symbolic or practical in nature. Overall, the image evokes a sense of mystery and intrigue due to its lack of context and content. User: is it just a black square? Llama: Yes, it is just a black square.

  Interesting, I uploaded a pure white 50x50 png and got this: > User: Describe this image in the most detailed way possible > Llama: The image displays a large, mostly white background with some small gray areas. There is also an orange dot on the right side of the scene, which stands out against the predominantly white and gray backdrop. > User: Is it just a white square? > Llama: No, it is not just a white square. The image also contains some gray and tan colors as well. It appears to be an abstract art piece with various shades of color, making the overall appearance more interesting than a simple all-white background.

This is really impressive. I am glad locally hosted LLMs is a thing. It would be disastrous if e.g. "OpenAI" would get monopoly on these programs.

I guess I need to buy a new computer soon, to be able to run these in their big variants.

  - brucethemoose2 3y ago
    > On Windows, that usually means you need to open up the MSVC x64 native command prompt and run llamafile there, for the first invocation, so it can build a DLL with native GPU support. After that, $CUDA_PATH/bin still usually needs to be on the $PATH so the GGML DLL can find its other CUDA dependencies. Yeah, I think the setup lost most users there. A separate model/app approach (like Koboldcpp) seems way easier TBH. Also, GPU support is assumed to be CUDA or Metal.

Extremely cool and Justine Tunney / jart does incredible portability work [0], but I'm kind of struggling with the use-cases for this one. I make a small macOS app [1] which runs llama.cpp with a SwiftUI front-end. For the first version of the app I was obsessed with the single download -> chat flow and making 0 network connections. I bundled a model with the app and you could just download, open, and start using it. Easy! But as soon as I wanted to release a UI update to my TestFlight beta testers, I was causing them to download another 3GB. All 3 users complained :). My first change after that was decoupling the default model download and the UI so that I can ship app updates that are about 5MB. It feels like someone using this tool is going to hit the same problem pretty quick when they want to get the latest llama.cpp updates (ggerganov SHIIIIPS [2]). Maybe there are cases where that doesn't matter, would love to hear where people think this could be useful.

It’s just a zip file, updating it should be doable in place while it’s running on any non windows platform and you just need to swap that one file out you changed. When it’s running in server mode you could also possibly hot reload the executable without the user even having any downtime.

  You could also change you code so that when it runs, it checks as early as possible if you have a file with a well known name (say ~/.freechat.run) and then switches to reading from it instead for the assets than can change. You could have multiple updates my using say iso time and doing a sort (so that ~/.freechat.run.20231127120000 would be overriden by ~/.freechat.run.20231129160000 without making the user delete anything)

> you pass the --n-gpu-layers 35 flag (or whatever value is appropriate) to enable GPU This is a bit like specifying how large your strings will be to a C program. That was maybe accepted in the old days, but not anymore really.

tomwojcik 3y ago
That's not the limitation introduced in Llamafile. It's actually a feature of all gguf models. If not specified, GPU is not used at all. Optionally, you can offload some work to the GPU. This allows to run 7b models (zephyr, mistral, openhermes) on regular PCs, it just takes a bit more time to generate the response. What other API would you suggest?
- amelius 3y ago
  This is a bit like saying if you don't specify "--dram", the data will be stored on punchcards. From the user's point of view: they just want to run the thing, and as quickly as possible. If multiple programs want to use the GPU, then the OS and/or the driver should figure it out.
  - andersa 3y ago
    They don't, though. If you try to allocate too much VRAM it will either hard fail or everything suddenly runs like garbage due to the driver constantly swapping it / using shared memory. The reason for this flag to exist in the first place is that many of the models are larger than the available VRAM on most consumer GPUs, so you have to "balance" it between running some layers on the GPU and some on the CPU. What would make sense is a default auto option that uses as much VRAM as possible, assuming the model is the only thing running on the GPU, except for the amount of VRAM already in use at the time it is started.
    - insanitybit 3y ago
      > They don't, though. If you try to allocate too much VRAM it will either hard fail or everything suddenly runs like garbage due to the driver constantly swapping it / using shared memory. What I don't understand is why it can't just check your VRAM and allocate by default. The allocation is not that dynamic AFAIK - when I run models it all happens basically upfront when the model loads. ollama even prints out how much VRAM it's allocating for model + context for each layer. But I still have to tune the layers manually, and any time I change my context size I have to retune.

I think the best way to try this out is with LLaVA, the text+image model (like GPT-4 Vision). Here are steps to do that on macOS (which should work the same on other platforms too, I haven't tried that yet though): 1. Download the 4.26GB llamafile-server-0.1-llava-v1.5-7b-q4 file from https://huggingface.co/jartine/llava-v1.5-7B-GGUF/blob/main/llamafile-server-0.1-llava-v1.5-7b-q4 https://huggingface.co/jartine/llava-v1.5-7B-GGUF/blob/main/...: wget https://huggingface.co/jartine/llava-v1.5-7B-GGUF/resolve/main/llamafile-server-0.1-llava-v1.5-7b-q4 2. Make that binary executable, by running this in a terminal: chmod 755 llamafile-server-0.1-llava-v1.5-7b-q4 3. Run your new executable, which will start a web server on port 8080: ./llamafile-server-0.1-llava-v1.5-7b-q4 4. Navigate to http://127.0.0.1:8080/ http://127.0.0.1:8080/ to upload an image and start chatting with the model about it in your browser.

jart 3y ago
You need at minimum a stock operating system install of: - Linux 2.6.18+ (arm64 or amd64) i.e. any distro RHEL5 or newer - MacOS 15.6+ (arm64 or amd64, gpu only supported on arm64) - Windows 8+ (amd64) - FreeBSD 13+ (amd64, gpu should work in theory) - NetBSD 9.2+ (amd64, gpu should work in theory) - OpenBSD 7+ (amd64, no gpu support) - AMD64 microprocessors must have SSSE3. Otherwise llamafile will print an error and refuse to run. This means, if you have an Intel CPU, it needs to be Intel Core or newer (circa 2006+), and if you have an AMD CPU, then it needs to be Bulldozer or newer (circa 2011+). If you have a newer CPU with AVX or better yet AVX2, then llamafile will utilize your chipset features to go faster. No support for AVX512+ runtime dispatching yet. - ARM64 microprocessors must have ARMv8a+. This means everything from Apple Silicon to 64-bit Raspberry Pis will work, provided your weights fit into memory. I've also tested GPU works on Google Cloud Platform and Nvidia Jetson, which has a somewhat different environment. Apple Metal is obviously supported too, and is basically a sure thing so long as xcode is installed.

dekhn 3y ago

I get the desire to make self-contained things, but a binary that only runs one model with one set of weights seems awfully constricting to me.

Eh, this is exploring a more “static link” approach for local use and development vs the more common “dynamic link” that API providers offer. (Imperfect analogy since this is literally like a DLL but… whatever). Probably makes sense for private local apps like a PDF chatter.

There's also a "llamafile" 4MB binary that can run any model (GGUF file) that you pass to it: https://simonwillison.net/2023/Nov/29/llamafile/#llamafile-trying-other-models https://simonwillison.net/2023/Nov/29/llamafile/#llamafile-t...
- dekhn 3y ago
  Right. So if that exists, why would I want to embed my weights in the binary rather than distributing them as a side file? I assume the answers are "because Justine can" and "sometimes it's easier to distribute a single file than two".
  - simonw 3y ago
    Personally I really like the single file approach. If the weights are 4GB, and the binary code needed to actually execute them is 4.5MB, then the size of the executable part is a rounding error - I don't see any reason NOT to bundle that with the model.
    - dekhn 3y ago
      I guess in every world I've worked in, deployment involved deploying a small executable which would run millions of times on thousands of servers, each instance loading a different model (or models) over its lifetime, and the weights are stored in a large, fast filesystem with much higher aggregate bandwidth than a typical local storage device. The executable itself doesn't even contain the final model- just a description of the model which is compiled only after the executable starts (so the compilation has all the runtime info on the machine it will run on). But, I think llama plus obese binaries must be targeting a very, very different community- one that doesn't build its own binaries, runs in any number of different locations, and focuses on getting the model to run with the least friction.

From a technical standpoint, this project is really fascinating. I can see a lot of use cases for getting something up fast locally for an individual user.

Fantastic. For those of who who swim in the Microsoft ecosystem, and do not compile Linux apps from code, what Linux dustro would run this without fixing a huge number of dependencies? It seems like someone would have included Llama.cpp in their distro, ready-to-run. Yes, I'm an idiot.

llamafile runs on all Linux distros since ~2009. It doesn't have any dependencies. It'd probably even run as the init process too (if you assimilate it). The only thing it needs is the Linux 2.6.18+ kernel application binary interface. If you have an SELinux policy, then you may need to tune things, and on some distros you might have to install APE Loader for binfmt_misc, but that's about it. See the Gotchas in the README. Also goes without saying that llamafile runs on WIN32 too, if that's the world you're most comfortable with. It even runs on BSD distros and MacOS. All in a single file.

  It doesn't seem to run on NixOS, though I'm new to Nix and may be missing something. $ ./llava-v1.5-7b-q4-server.llamafile --help ./llava-v1.5-7b-q4-server.llamafile: line 60: /bin/mkdir: No such file or directory Regardless, this (and Cosmopolitan) are amazing work - thank you!

    The APE shell script needs to run /bin/mkdir in order to map the embedded ELF executable in memory. It should be possible for you to work around this on Linux by installing our binfmt_misc interpreter: sudo wget -O /usr/bin/ape https://cosmo.zip/pub/cosmos/bin/ape-$(uname -m).elf sudo sh -c "echo ':APE:M::MZqFpD::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register" sudo sh -c "echo ':APE-jart:M::jartsr::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register" That way the only file you'll need to whitelist with Nix is /usr/bin/ape. You could also try just vendoring the 8kb ape executable in your Nix project, and simply executing `./ape ./llamafile`.

Nice but you are leaving some performance on the table (if you have a GPU) Exllama + GPTQ is the way to go llama.cpp && GGUF are great on CPUs More data: https://oobabooga.github.io/blog/posts/gptq-awq-exl2-llamacpp/ https://oobabooga.github.io/blog/posts/gptq-awq-exl2-llamacp...

great! worked easily on desktop Linux, first try. It appears to execute with zero network connection. I added a 1200x900 photo from a journalism project and asked "please describe this photo" .. in 4GB of RAM, it took between two and three minutes to execute with CPU-only support. The response was of mixed value. On the one hand, it described "several people appear in the distance" but no, it was brush and trees in the distance, no other people. There was a single figure of a woman walking with a phone in the foreground, which was correctly described by this model. The model did detect 'an atmosphere suggesting a natural disaster' and that is accurate. thx to Mozilla and Justin Tunney for this very easy, local experiment today!

If my reading is correct, this literally just distribute an LLM model and code, and you need to do some tasks - like building - to make it actually run, right? And for this, you need to have additional tools installed?

simonw 3y ago
You don't need to do any extra build tasks - the file should be everything you need. There are some gotchas to watch out for though: https://github.com/mozilla-Ocho/llamafile#gotchas https://github.com/mozilla-Ocho/llamafile#gotchas

Wow, it has CUDA support even though it's built with Cosmopolitan? Awesome, I see Cosmopolitan just this month added some support for dynamic linking specifically to enable GPUs! This is amazing, I'm glad they found a way to do this. https://github.com/jart/cosmopolitan/commit/5e8c928f1a37349a8c72f0b6aae5e535eace3f41 https://github.com/jart/cosmopolitan/commit/5e8c928f1a37349a... I see it unfortunately requires the CUDA developer toolkit to be installed. It's totally possible to distribute CUDA apps that run without any dependencies installed other than the Nvidia driver. If they could figure that out it would be a game changer.

I like the idea of putting it in one file but not an executable file. Using CBOR (MessagePack has a 4gb bytestring limit) and providing a small utility to copy the executable portion and run it would be a win. No 4gb limit. It could use delta updates.

Small field test: I uploaded a picture of a typical small Korean Buddhist temple, with a stone pagoda in front. Anyone at all familiar with East Asian Buddhism would instantly recognize both the pagoda and the temple behind it as Korean. Llamafile: "The image features a tall, stone-like structure with many levels and carved designs on it. It is situated in front of an Asian temple building that has several windows. In the vicinity, there are two cars parked nearby – one closer to the left side of the scene and another further back towards the right edge. . ." ChatGPT4:"The photo depicts a traditional Korean stone pagoda, exhibiting a tiered tower with multiple levels, each diminishing in size as they ascend. It is an example of East Asian pagodas, which are commonly found within the precincts of Buddhist temples. . . The building is painted in vibrant colors, typical of Korean temples, with green being prominent." No comparison, alas.

simonw 3y ago
That's not a llamafile thing, that's a llava-v1.5-7b-q4 thing - you're running the LLaVA 1.5 model at a 7 billion parameter size further quantized to 4 bits (the q4). GPT4-Vision is running a MUCH larger model than the tiny 7B 4GB LLaVA file in this example. LLaVA have a 13B model available which might do better, though there's no chance it will be anywhere near as good as GPT-4 Vision. https://github.com/haotian-liu/LLaVA/blob/main/docs/MODEL_ZOO.md#llava-v15 https://github.com/haotian-liu/LLaVA/blob/main/docs/MODEL_ZO...

Can someone explain why we would want to use this instead of an OCI manifest?

Supports more platforms? (No joke)

dws 3y ago

Can confirm that this runs on an ancient i3 NUC under Ubuntu 20.04. It emits a token every five or six seconds, which is "ask a question then go get coffee" speed. Still, very cool.

tannhaeuser 3y ago

Does it use Metal on Mac OS (Apple Silicon)? And if not, how does it compare performance-wise against regular llama.cpp? It's not necessarily an advantage to pack everything (huge quantified 4bit? model and code) into a single file, or at least it wasn't when llama.cpp was gaining speed almost daily.

simonw 3y ago
It uses the GPU on my M2 Mac - I can see it making use of that in the Activity Monitor GPU panel.
- jart 3y ago
  Correct. Apple Silicon GPU performance should be equally fast in llamafile as it is in llama.cpp. Where llamafile is currently behind is at CPU inference (only on Apple Silicon specifically) which is currently going ~22% slower compared to a native build of llama.cpp. I suspect it's due to either (1) I haven't implemented support for Apple Accelerate yet, or (2) our GCC -march=armv8a toolchain isn't as good at optimizing ggml-quant.c as Xcode clang -march=native is. I hope it's an issue we can figure out soon!
- boywitharupee 3y ago
  currently, on apple silicon "GPU" <> "Metal" are synonymous. yes, there are other apis (opengl,opencl) to access the gpu but they're all deprecated. technically, yes, this is using Metal.

novaomnidev 3y ago

Why is this faster than running llama.cpp main directly? I’m getting 7 tokens/ sec with this. But 2 with llama.cpp by itself

Noob question - how might I call this from my Python script? Say as a replacement gpt3.5 turbo of sorts. Is there an option without GUI? This is great thank you, very user friendly (exhibit a: me)

simonw 3y ago
The llama.cpp server version runs a JSON API that you can call. It's currently missing any documentation though as far as I can tell - I found dome details on Reddit: https://www.reddit.com/r/LocalLLaMA/comments/185kbtg/llamacpp_server_rocks_now/ https://www.reddit.com/r/LocalLLaMA/comments/185kbtg/llamacp...

Ah, so like SQLite but for model weights. Edit: No, actually a lot more than that, but not a bad tagline.

Im sure this is great, but not screenshot of the GUI?

  Thank you, is there a way to select a different model? How does the model perform? Just general question if anyone else knows the answers while I try and clear space on my laptop ( why these things fill up so fast!)

    Token/second performance has been excellent for me. You can use this to run any if the thousands of of GGUF models on Hugging Face, see note here: https://simonwillison.net/2023/Nov/29/llamafile/#llamafile-trying-other-models https://simonwillison.net/2023/Nov/29/llamafile/#llamafile-t...

It’s intriguing to observe how this model is hallucinating. I presented it with Albert Bierstadt’s painting “In the Mountains” (https://www.wikiart.org/en/albert-bierstadt/in-the-mountains-1867 https://www.wikiart.org/en/albert-bierstadt/in-the-mountains...). To my surprise, it maintains that cows are scattered throughout the scene, despite being told otherwise. User: Llama: The image features a serene landscape with mountains in the background and a river flowing through it. A picturesque scene unfolds as two trees are visible near the water, adding to the natural beauty of the environment. In addition to these elements, there is an interesting detail: several cows can be seen standing on or around the grassy area next to the body of water. The presence of these animals creates a sense of tranquility and harmony with nature in this idyllic setting. User: There are no cows. Could it be that you've mistaken rocks for cows? Llama: No, the rocks in this image are not mistaken for cows. They can be seen near a lake with mountains in the background and trees surrounding it. The painting captures a serene landscape where nature is beautifully displayed. This picturesque scene showcases both the majestic mountain range and the tranquil body of water, creating an idyllic atmosphere that evokes feelings of peacefulness and relaxation. User: There are no cows! Llama: The image depicts a serene scene of mountains and water. A beautiful lake is surrounded by majestic snow-capped mountains, creating an idyllic landscape. In the foreground, there are trees adding to the natural beauty of the environment. A few birds can be seen flying in the sky above the lake, further enhancing the peaceful atmosphere. The presence of a boat on the water adds another element of leisure and enjoyment to this picturesque scene. Overall, it is an inviting image that showcases nature's wonders with its combination of mountains, lake, trees, birds, and boats.

Hmmm no matter what image I upload, it's somehow not seeing it. Got a chuckle out of this, though: --- User: Describe the image in the most detailed way possible Llama: The image is a close-up of an empty, dark room with no visible objects or people. It appears to be a black background photo that highlights the darkness and emptiness of the space. This could potentially represent an artistic representation or an actual setting where lighting has been used to emphasize the contrast between light and shadow. The focus on this particular area suggests that it might have some significance, whether symbolic or practical in nature. Overall, the image evokes a sense of mystery and intrigue due to its lack of context and content. User: is it just a black square? Llama: Yes, it is just a black square.

CaptainFever 3y ago
That's comedic. I love it.
sebmellen 3y ago
Interesting, I uploaded a pure white 50x50 png and got this: > User: Describe this image in the most detailed way possible > Llama: The image displays a large, mostly white background with some small gray areas. There is also an orange dot on the right side of the scene, which stands out against the predominantly white and gray backdrop. > User: Is it just a white square? > Llama: No, it is not just a white square. The image also contains some gray and tan colors as well. It appears to be an abstract art piece with various shades of color, making the overall appearance more interesting than a simple all-white background.

  LLM vision is surprisingly human-like. Point an actual human at a blank canvas and I'll bet many would hallucinate things that aren't there.

Which is a smaller model, that gives good output and that works best with this. I am looking to run this on lower end systems. I wonder if someone has already tried https://github.com/jzhang38/TinyLlama https://github.com/jzhang38/TinyLlama, could save me some time :)

SnowingXIV 3y ago

Incredible, up and running offline at 104ms per token with no additional configurations. Worked with various permutations of questions and outputs. The fact this is so readily available is wonderful. Using xdg make a nice little shortcut to drop in to automatically fire this off, open up a web browser, and begin.

I want to replicate the ROM personality of McCoy Pauley that Case steals in Neuromancer by tuning an LLM to speak like him, and dumping a llamafile of him onto a USB stick.

rightbyte 3y ago

This is really impressive. I am glad locally hosted LLMs is a thing. It would be disastrous if e.g. "OpenAI" would get monopoly on these programs. The model seems worse than the original ChatGPT at coding. However the model is quite small. It certainly could be a NPC in some game. I guess I need to buy a new computer soon, to be able to run these in their big variants.

This is the first time I'm able to get a chat model to work this easily. Although I can't see myself using it as it is very limited in UI, quality and context length in and out vs ChatGPT
