OpenAI Responses API adds async tools, steering

OpenAI’s Responses API now lets GPT-6 Astra continue independent work while application-managed tools run asynchronously. Developers can also steer active responses over WebSocket while preserving completed work and task context.

// ANALYSIS

This pushes tool-calling agents toward event-driven runtimes, reducing idle latency while making application orchestration more complex.

–Async tools keep long-running calls from blocking unrelated reasoning or output
–Developers must manage pending work, retries, correlation, and original call IDs
–Mid-turn steering enables corrections without restarting an entire agent task
–Steering requires GPT-6 Astra and Responses API WebSocket transport
–The latency gains are compelling, but Astra’s premium token pricing makes efficient orchestration essential

Claude Formalizes Fermat’s Last Theorem

Anthropic says Claude produced the first end-to-end, computer-checked formalization of Fermat’s Last Theorem in Lean in 11 days, generating 13 million lines of code and 29,500 intermediate theorems. The open-source artifact uses Prove2Me and a multi-agent harness, following a Wiles–Taylor–Wiles exposition.
