- hanspagel 25d agoShould I be able to see the actual results? Because I don’t see a hangar anywhere.
- fig781 25d agoQwen with open code seemed like the best to me. It seemed like the best balance between performance and visuals
- amenghra 25d agoAstra has so much more detail. It did take 5x more time, but that's usually negligible when it replaces x hours of human output.
- rao-v 25d agoIt’s really interesting how much little choices make the result better or worse. Astra and one of the GLMs added bright lights, and thus looked so much better to my eye. Genuinely happy with some of the Qwen 3.8 results (especially since I can run that model at Q8). Interesting to see how much better (at this task) Pi (OMP) is over Opencode as a harness. I’d love to see a few more with outcomes that are as easy to judge but less subjective. I’ve got a toy project going to make a fun to watch battle simulator where an LLM (or two if playing vs) has to write programs that control multiple bots (each with their own line of sight and limited battle context) that have to coordinate and fight alongside each other. Goal is to have the LLM update the code based on current situations maybe 5-10 times in a 5 min simulated battle. Exploring even allow the bots to request new programming and score based on number of reprogram steps.
- alvins82 25d agoInteresting also that Astra and Sol didn't check visually using the browser. I suspect they would have done even better if they had.
- riversflow 25d agohuh. goes to show how much browser selection impacts things. the OMP Qwen result is completely unresponsive in free cam on my iphone, whereas the opencode version is responsive, has multitouch zoom and multitouch pan. the glm models do really well with this as well, but all of the anthropic models have pretty gimped camera controls, even astra, which while pretty wont let me pan and only allows me to rotate about 120 degrees! I’m really impressed with the Qwen 27b OpenCode result. I suppose the only thing that the prompt asks for is the cinematic view, and honestly they all kinda fail on the “subtle volumetric-style fog planes”, none of them have more fog when you get farther from a light source.
- andai 25d agoYeah, most of them made it too dark to see what's going on. Also your last paragraph sounds like the setup for a late 80s scifi movie...
- utopiah 25d agoI wish there was another column with the estimated cost for each, with a specific date. Ideally also finding somehow (not sure what would be the right away) what is publicly available before running the test. It's quite a different outcome if there are competitions, e.g. js13k, live code examples from books, even templates, on specific that topic. Visually here the results looks very very similar to the point that I can't help but wonder if it's the result from the short yet relatively descriptive prompt or because some template was always found and relied on.
- alvins82 25d agoI've just pushed the transcripts of each if that helps. https://github.com/alvins82/hangar-harness-model-tests https://github.com/alvins82/hangar-harness-model-tests
- utopiah 24d agoThanks, sorry to be asking for more but what about a Web visualization of the transcripts?
- anotherCodder 25d ago[dead]
- alvins82 25d agoAdded costs.
- utopiah 24d agoMuch appreciated
- BurpyDave 25d agoSo where did most of them get the idea of calling it hanger 07?

- knighthacker 25d ago[flagged]
- karlkloss 25d agoWhat I'm missing in all of those one-shot tests: How different are the results between multiple runs of the same setup?
- alvins82 25d agoI have done multiple runs on Qwen3.8 27B. Results are close enough across multiple runs qualitatively.
- poilcn 25d agoNice. But these tests raise a question what results are reproducible, the final visual, time, tool calling or it's mostly noise. Like, have you tried same combination or model and harness multiple times?
- ande-mnoc 25d agoRefreshing to see a post that gets straight to the point and not hide the data behind pages of prose.
- onion2k 25d agoThe Astra version seems to have used three.js r170, which is from October 2024. Sol used an even earlier version. GLM's code used the latest version, but I think it's just getting three.js@latest from jsdelivr so it's unlikely to be writing code against that version. Qwen on OpenCode also fetches from jsdelivr, but using a pinned version at r160. I don't think any of these examples are using things like tone mapping so they're stuck in sRGB (AgX or ACES look much better), they're not using the node materials (good for programmatic texture implementation), and they're not doing anything cool like baking shadow environments or using post-processing effect. They're nice, but I think they're showing how far behind AI models are on this sort of project rather than how good they are.
- scroogey 25d agoAnyone know of pertinent skill files to nudge the agents into these directions?
- avaer 25d agoDon't use skills. Point it to a game engine or better yet full game repo or whatever and ask for what you want.
- rao-v 25d agoReally appreciate this perspective. It’s tempting to stop at being amazed at what these models can do, but my experience matches yours - they need help with details to do well.
- SadErn 25d ago[dead]
- warpech 25d agoWhat’s a good way to drive models to use current versions?
- laruss5 25d ago[flagged]
- reilly3000 25d agoI love everything about OpenCode except for the stuff it outputs. On paper it has everything I want in a harness and more, but it tends to struggle to deliver the desired outcome. Last I used it the context was massive and tool calls were reliably unreliable. Is it worth revisiting as a daily driver?

- alvins82 25d agoBtw in my quest for a good desktop codex/claude like app - https://github.com/openchamber/openchamber https://github.com/openchamber/openchamber - this seems to be front-runner. I pair it with OMP via https://github.com/alvins82/omp-openchamber-server/ https://github.com/alvins82/omp-openchamber-server/. I wanted a powerful GUI+harness setup for open models so I could use/test as they came out.
- pprotas 25d agoI like Paseo https://github.com/getpaseo/paseo https://github.com/getpaseo/paseo But I am annoyed at these GUIs implementing features I don’t care about. I want them to just wrap my harness and forward it to my iPhone, but they can’t help themselves from feature creep.
- alvins82 25d agoI did try this - I found it overly dev focused - e.g. git +/- changes in left sidebar. I wanted something close to what I am use to with Codex/Claude - just for open models.
- Fuzzwah 25d agoI've been impressed with orca https://github.com/stablyai/orca https://github.com/stablyai/orca I did have some issues getting it installed on a headless server. I sort of gave up and installed the instance that I use as the remote server on a Debian + xfce machine I had laying around.
- dandaka 25d agoI found it appalling when working with remote setup — tabs disappearing and appearing after some time, screen hangs up, projects disappear. Tried to fix some issues with PR, but team is not accepting for 2w+.
- mmmmbbbhb 25d agoDeepSeek harness is for you
- 0xanushshetty 25d ago[flagged]
- chvid 25d agoWhat is DSH / PTC?
- alvins82 25d agoDeepseek Harness. PTC is one of the 'modes' it has.
- faangguyindia 25d agoPtc is programmatic tool calling or code mode Basically it can run these mini programs where each input might be another toolcall, so it can run without waiting for whole LLM response and ready the parameters async.
- sashank_1509 25d agoI’m always confused, are all these shapes programmatically generated or are they downloaded from some source? Also I think Astra looks the best and has the best functionality. Also shocked how much better GLM is on the Non Codex harnesses. Didn’t think it would make such a difference. Would be nice if you could include cost in the table
- alvins82 25d agoAdded costs.
- meerita 25d agoI saw examples on X of people building amazing things with Three.js and models, and I figured out how to build them myself. But the results are mostly low-poly materials and crappy animations (pretty sure because I am not the best at these things). I thought it was my prompt (it was detailed), but it seems to be mostly a limitation of the models. From all the examples I've seen, Astra does it really well, and I suspect it's because they wanted to attract game designers, so they trained the model more on 3D, animation libraries, etc.
- sampullman 25d agoSol and Opus are pretty good with the right prompting and feedback framework. Or, my standards are lower. It's sometimes hard to tell in these discussions whether people are talking about getting production quality results, or stuff that's good enough for a one off blog post.
- aetherspawn 25d agoWould be good to include Fable and Opus. Based on the results with Astra vs GLM (not even in the same ballpark), these are probably the realistic alternatives to consider.
- bensyverson 25d agoYes, I'd be really interested to see Fable / Opus / Sonnet. GLM 5.3 Flash Max had an interesting showing. Its Codex version was bad [0], and it completed in 9 minutes. The OpenCode version was much richer [1] and more detailed, completed in 20 minutes. And the OMP version was arguably the most complete [2], completing in 30 minutes. This is probably the strongest argument for the effect of a harness, and I'd be interested to learn the differences in the prompts and tools between these three.

- grigio 25d agocool, I've tested different harnesses with the same model. can you add jcode harness? I had great results with that https://grigio.github.io/ship-harness-bench/ https://grigio.github.io/ship-harness-bench/
- webprofusion 25d agoThis is rad, the Sol one is probably the coolest.
- yanhangyhy 25d agoto me i think the diffrenece is not that big?
- quietraster 25d agofun benchmark. did any harness consistently win regardless of model, or is it more about the pairing?
- alexchamberlain 25d agoAm I missing something or does sorting by Duration not work? Chrome on Android mobile
- hudo 25d agoDamn its unreal how much Astra is better than anything else :( Would be cool to see total cost
- deleted 25d ago[deleted]
- alvins82 25d agoAdded costs.
- _pdp_ 25d agoHow do you judge which one produces the best result? They all look the same to me more or less.
- simonwsimonw 25d ago[dead]
- consumer451 25d agoWhy no Antrhopic models?
- stuaxo 25d agoWe have differing ideas of what a simple prompt contains.
- andai 25d agoBuild me an actual hangar. Make no mistakes.
- jonasdn 25d agoWhere did they all get "Hangar 07" from?
- andai 25d agoWTF, Astra looks like a Unity demo project. That's way better than I was expecting. Would love to see Claude and Gemini as well. (And it would be nice to include the total cost in the table.)
