We’ve developed Claude for Chrome, where Claude works directly in your browser and takes actions on your behalf. We’re releasing it at first as a research preview to 1,000 users, so we can gather real-world insights on how it’s used. https://x.com/AnthropicAI/status/1960417002469908903
“To test models’ performance on Claude Code, we ran GLM-4.5 against Claude Sonnet 4 and other open-source models on 52 practical programming tasks. While GLM-4.5 demonstrated strong performance against top open-source models, it secured a 40.4% win rate against Claude Sonnet 4. https://x.com/Zai_org/status/1962522761630482700

Have been tinkering with GLM 4.5 for about an hour. It is about 3x faster than Claude Code + Opus 4.1 and 5x faster than GPT-5-high, but still feels just as good as closed-source models. I am definitely more productive than with other models due to GLM-4.5’s speed.”” / X https://x.com/Tim_Dettmers/status/1962603940291260533
