Same. When I try to get it to do a simple loop (eg take screenshot, click next, repeat) it'll work for about five iterations (out of a hundred or so desired) then say, "All done, boss!"
I'm hoping Anthropic's browser extension is able to do some of the same "tricks" that Claude Code uses to gloss over these kinds of limitations.
Claude is extremely poor at vision when compared to Gemini and ChatGPT. i think anthropic severely overfit their evals to coding/text etc. use cases. maybe naively adding browser use would work, but I am a bit skeptical.
I have a completely different experience. Pasting a screenshot into CC is my de-facto go-to that more often than not leads to CC understanding what needs to be done etc…
I have better success with asking for a short script that does the million iterations than asking the thing to make the changes itself (edit: in IDEs, not in the browser).
I'm wondering if they are using vanilla claude or if they are using a fine-tuned version of claude specifically for browser use.
RL fine-tuning LLMs can have pretty amazing results. We did GRPO training of Qwen3:4B to do the task of a small action model at BrowserOS (https://www.browseros.com/) and it was much better than running vanilla Claude, GPT.
