Anthropic released version 0.90.0 of its Python SDK on April 7, 2026, adding support for the claude-mythos-preview model. The update also includes a bug fix for query parameter merging in the client.

OpenAI has acquired Astral, the company behind widely-used Python development tools Ruff, uv, and ty, which see hundreds of millions of downloads monthly. The tools will integrate with OpenAI's Codex platform to enable agentic AI systems that can plan changes, modify codebases, run tools, and verify results. OpenAI commits to keeping the tools open source under permissive licenses post-acquisition.
