OpenAI Agents SDK alpha changes three configuration surfaces

Brief

By Dextape Desk · November 8, 2026

OpenAI's Agents SDK version 0.24.0-alpha.7 is a prerelease, according to the official notes and GitHub's release record. The alpha changes defaults and accepted values across three configuration areas. New Environments default to strict write policy, which needs a compatible Linux or macOS executor, while the working directory stays writable and extra paths go through writable_roots. Teams wanting the former remote policy can choose legacy, though saved remote checkpoints must name it on restore; reopening them alone leaves the policy unchanged. Old MCP approval names auto and approve are rejected in favor of native and preapproved, which keep their behavior. For three named models, the bundled catalog moves default reasoning effort from low to medium, and developers can restore low explicitly. The notes do not say existing deployments change automatically or report any output-quality effect.

Why it matters: Changed defaults and accepted configuration names can decide whether existing agent setups keep working, so builders relying on them need to know what is documented.
