> When you click it, the locally running LLM gets a copy of the web site in the context window, and you get to ask it a prompt, e.g. "summarize this". I'm also now imagining my GPU whirring into life and the accompanying sound of a jetplane getting ready for takeoff, as my battery suddenly starts draining visibly. Local LLMs for are a pipe dream, the technology fundamentally requires far too much computation for any true intelligence to ever make sense with current computing technologies.

Most laptops are now shipping with a NPU for handling these tasks. So it wont be getting computed on your GPU.

  That doesn't mean anything, it's just a name change. They're the same kind of unit. And whatever accelerator you try to put into it, you're not running Gemini3 or GPT-5.1 on your laptop, not in any reasonable time frame.
  - AuthAuth 11mo ago
    Also it does mean something. An NPU is completely different from your 5070. Yes the 5070 has specific AI cores but it also has raster cores and other things not present in an NPU. You dont need to run GPT5.1 to summerize a webpage. Models are small and specialized for different tasks.

      And all of that is irrelevant for the AI use case. The NPU is at best slightly more efficient than a GPU for this use case, and mostly its just cheaper by forgoing various parts of a GPU that are not useful for AI (and would not be used during inferencing anyway). And the examples being given of why you'd want AI in your browser are all general text comprehension and conversational discussions about that text, applied to whatever I may be browsing. It doesn't really get less specialized than that.

    Over the last few decades I've seen people make the same comment about spell checking, voice recognition, video encoding, 3D rendering, audio effects and many more. I'm happy to say that LLM usage will only actually become properly integrated into background work flow when we have performant local models. People are trying to madly monetise cloud LLMs before the inevitable rise of local only LLMs severely diminishes the market.

      Time will tell, but right now we're not solving the problem of running LLMs by increasing efficiency, we're solving it by massive, unprecedented investments in compute power and just power. Companies definitely weren't building nuclear power stations to power their spell checkers or even 3D renderers. LLMs are unprecedented in this way.
      - Intermernet 11mo ago
        True, but the usefulness of local models is actually getting better. I hope that the current unprecedented madness is a factor of the potential of cloud models, and not a dismissal of the possibility of local models. It's the biggest swing we've seen (with the possible exception of cloud computing vs local virtualisation) but that may be due to recognition of the previous market behaviour, and a desperate need to not miss out on the current boom.

    No, NPUs are designed to be power efficient in ways GPU compute aren't. You also don't need Gemini3 or GPT anything running locally.
    - tsimionescu 11mo ago
      Personally, I don't need AI in my browser at all. But if I did, why would I want to run a crappy model that can't think and hallucinates constantly, instead of using a better model that kinda thinks and doesn't hallucinate quite as often?
      - heavyset_go 11mo ago
        I generally agree with you, but you'd be surprised at what lower parameter models can accomplish. I've got Nemo 3 running on an iGPU on a shitty laptop with SO-DIMM memory, and it's good enough for my tasks that I have no use for cloud models. Similarly, Granite 4 based models are even smaller, just a couple of gigabytes and are capable of automation tasks, summarization, translation, research etc someone might want in a browser. Both do chain of reasoning / "thinking", both are fast, and once NPU support lands in runtimes, they can be offloaded on to more efficient hardware. They certainly aren't perfect, but at least in my experience, fuzzy accuracy / stochastic inaccuracy is good enough for some tasks.

That's the point. For things like summarizing a webpage or letting the user ask questions about it, not that much computation is required. An 8B Ollama model installed on a middle of the road MacBook can do this effortlessly today without whirring. In several years, it will probably be all laptops.

  But what you would want to summarize a page. If I'm reading a blog, that means that I want to read it, not just a condensed version that might miss the exact information I need for an insight or create something that was never there.
  - CamperBob2 11mo ago
    You don't use it to summarize pages (or at least I don't), but to help understand content within a page while minimizing distractions. For example: I was browsing a Reddit thread a few hours ago and came upon a comment to the effect of "Bertrand Russell argued for a preemptive nuclear strike on the Soviets at the end of WWII." That seemed to conflict with my prior understanding of Bertrand Russell, to say the least. I figured the poster had confused Russell with von Neumann or Curtis LeMay or somebody, but I didn't want to blow off the comment entirely in case I'd missed something. So I highlighted the comment, right-clicked, and selected "Explain this." Instead of having to spend several minutes or more going down various Google/Wikipedia rabbit holes in another tab or window, the sidebar immediately popped up with a more nuanced explanation of Russell's actual position (which was very poorly represented by the Reddit comment but not 100% out of line with it), complete with citations, along with further notes on how his views evolved over the next few years. It goes without saying how useful this feature is when looking over a math-heavy paper. I sure wish it worked in Acrobat Reader. And I hope a bunch of ludds don't browbeat Mozilla into removing the feature or making it harder to use.

      And this explanation is very likely to be entirely hallucinated, or worse, subtly wrong in ways that's not obvious if you're not already well versed in the subject. So if you care about the truth even a little bit, you then have to go and recheck everything it has "said". Why waste time and energy on the lying machine in the first place? Just yesterday I asked "PhD-level intelligence" for a well known quote from a famous person because I wasn't able to find it quickly in wikiquotes. It fabricated three different quotes in a row, none of them right. One of them was supposedly from a book that doesn't really exist. So I resorted to a google search and found what I needed in less time it took to fight that thing.
