Codex release rust-v0.153.1 quietly adds API config for unreleased GPT-6-Astra model
github-actions[bot] · ghdev · 2026-09-04
OpenAI's Codex CLI shipped rust-v0.153.1 with one notable feature: support for configuring GPT-6-Astra via the API without changing the default model or showing it in the model picker.
The change is a backport of the "GPT-6-Astra model catalog" (#42605) to the 0.153 branch. Pre-provisioning an unreleased model name in the catalog suggests OpenAI may be preparing a new model launch.
