Claude Code Front-End Usage and Comparison for Homepage Creation
By
–
Claude Code for front-end is heavily underrated. Below are 3 attempts to make a homepage for an ongoing project:
Claude Code – Lovable – V0
In my opinion, Claude Code did best! Plus you have all files locally so you can start editing right away
And you have full control over -
OpenAI’s new open models outperform previous SOTA Qwen
By
–
OpenAI's new open models are the new reference! Fewer parameters (both total and activated), yet much better performance than previous SOTA by Qwen EDIT: put the thinking scores for Qwen3, to be more fair!

Comparison of Qwen and OpenAI Model Performance on GPQA Benchmarks
By
–
I used GPQA for Qwen, not sure if it's the standard or the diamond set.
If Qwen uses the standard and not diamond, it's even more impressive to know that OpenAI models on the hardest set beat Qwen on the standard! -

Great insights by Manus team on engineering SOTA agents:
– KV cache is king in agents – filesystem is a great mechanism for memory
– keep errors in the trace
– and more

Example of web research, Drive, Terminal slides, and Operator validation
By
–
Example of cool capabilities unlocked by this : do research on the web and connect to Drive via Text browser, then create slides via Terminal, then view them through Operator to validate slides or go back to the drawing board.

Deep research and Operator limitations; Operator could do deep research
By
–
The team acknowledges that some agents are still very limited each in their own way:
– Deep research cannot interact with webpages (no Textbrowser can)
– Operator has trouble reading through long pages personal take: Operator should theoretically be able to also do deep research -
ChatGPT agent live announcement combining Deep Research, Operator, Terminal code editing
By
–
ChatGPT agent live announcement underway, with @sama onboard!
This Agent patches together
– Deep Research (TextBrowser )
– Operator (GUI Agent) – Terminal code editing
to unlock all these capacities together in an agent.
