Fable is insanely good at making native macos apps. Why can't Slack and other apps with bad UX just expose an SDK/API and then I build my own UI however I want??

Most powerful browser agent yet
Introducing: Browser Use CLI 3.0 🌐 Turn any model into a SOTA browser agent > Direct CDP control via browser-harness > Run on cloud browsers or real Chrome > 6Γ— smaller, fewer tokens Try it now πŸ”—β†“

I realized that goal setting is the core RL loop of a startup. Set a two-week goal Hit the goal? β†’ Reward signal. Reinforce what worked. Missed it? β†’ Negative reward. Diagnose root cause, update strategy, try again.

Sonnet 5 mogged by GLM 5.2
Claude sonnet 5 outperforms claude sonnet 4.6 and at a cheaper cost (much more efficient steps) Compared to opus, Sonnet 5 has 40% less cost of Opus, with 8% less performance However, GLM 5.2 has 2% score on Sonnet with 25% less cost

I went really deep into customer funnels to find the channels that work best and came to one simple conclusion. Biggest cohorts with highest LTV came from us launching new stuff. You can try to optimize your funnels as much as you want with but the truth is Just ship new stuff.

Video Use is trending again today on Github. My god haha it just won't stop growing. Maybe I should just hire someone to work on it and make it insane πŸ‘€

GLM 5.2 βš”οΈ Opus 4.7 βš”οΈ GPT 5.5 βš”οΈ Minimax M3 Should you use open-weight models? We're making a QA benchmark. Using Browser Use v4, we benchmarked these models > Send a task from the LLM Arena dataset to each > Generate the website, score with human evaluation Which model did the best? Check it out ↓

Our new cloud agent (live tomorrow) can make posters! Its so much nicer to see information in a styled page than plaintext. It can actually do a lot more than just posters, but more on that later... Try it tomorrow!

Use the QA skill in Browser Use v4. Your agent builds the app. Give Browser Use the URL and let it: > Test the flow and catch bugs > Click around like a user and judge the UI > Tell your agent what to fix Close the loop. Try it now ↓

I took a small step back from agent loops. My decisions are still better than LLM decisions. It makes you feel extremely productive but I would say it's an illusion of overconfidence. The quality of that software is not as high as manually iterating plan, perfectly understanding and judging those decisions, and making sure the LLM perfectly executes it. The one exception is software with "reward -> iterate" style optimization where constraints are very clear. You can just define the constraints and let the LLM cook. For example "build firecracker infra where browsers spin up in 400ms" -> the final state is very clear. In the last few weeks coding felt more like ML which feels magical when it works, sadly very rare though. I hope next models change this β€” maybe when Fable is back (I hope).

GLM 5.2 just beat Fable 5 at website design. 🌐 The crazy part: GLM is text-only. It can build the site, but it can’t inspect the result. So we paired it with Browser Use v2 multimodal QA subagents. > Reviews the site and finds bugs > Judges the aesthetics > Sends GLM targeted fixes to iterate on Build full QA cost less than $0.75. Try it now ↓
