Everyone is tired of reading AI slop. Anthropic says Opus 5.5 writes more naturally and actually follows instructions, so we ran an eval. We tested it against the new versions of OpenAI's GPT-6 Luna…

At Anthropic, Claude now writes 80% of our code. Engineers ship 8x more code per quarter. Side effect: Tests grew 10x. CI jobs up 25x in 6 months. Here's what helped us scale: https://t.co/WOL2r60…

We Must Pace the Frontier: I’ve written a new essay on why the AI industry should slow down, with a three-part plan for doing so. Anthropic is unilaterally committing to the first of these steps. We…

I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improvin…
