A well-implemented language model could be a huge QOL improvement. The fact that 90% of AI implementations are half-assed ChatGPT frontends does not reflect the utility of the models themselves; it only reflects the lack of vision and haste to ship of most companies.

Arc Browser has some interesting AI features, but since they're shipping everything to OpenAI for processing, it's a non-starter for me. It also means the developers' interests are not aligned with my own, since they are paying by the token for API access. Mozilla is going to run local LLMs, so everything will remain private, and limited only by my own hardware and my own configuration choices. I'm down with that.

I'd love to see Firefox auto-fetch results from web searches and summarize them for me, bypassing clickbait, filler, etc. You've probably seen AI summary bots here on Lemmy, and I find them very helpful at cutting the crap and giving me exactly what I want, which is information in text form. That's something that's harder and harder to get from web sites nowadays. Never see a recipe writer's life story again!
