Codex shipped two hotfixes in 26 hours purely to carry GPT-6 Astra into the 0.153 line
rust-v0.153.1 (2026-09-03 21:02 UTC) backports the GPT-6-Astra model catalog so the model can be configured through the API without changing the default or appearing in the model picker, and rust-v0.153.2 (2026-09-03 23:53 UTC) is a single-line correction of the Astra Fast tier description from "1.5x" to "2x speed, increased usage," text only. Both are one-PR releases against a 0.153.0 that shipped the same day. The catalog-without-picker shape is how OpenAI is now landing model support ahead of general availability.
