Simon Willison published a new March 22 entry on simonwillison.net covering the formal Astral-OpenAI integration, tagging it with python, openai, ruff, uv, astral, charlie-marsh, coding-agents, and codex-cli.

Willison remains the highest-signal analyst on open-source tooling concentration from AI company M&A.
