A model slug accepted by the Codex CLI and app-server.

Variants

Gpt6Astra

GPT-6-Astra (gpt-6-astra) — first GPT-6-family model in the catalog (272k context). Live-probed 2026-09-04: the backend recognizes the slug but rejects it for ChatGPT-plan auth (“not supported when using Codex with a ChatGPT account”).

DaybreakBlue

Daybreak Blue (gpt-daybreak-blue-latest) — the cyber-access program models (see CyberAccessProgram); server-side gated.

DaybreakRed

Daybreak Red (gpt-daybreak-red-latest) — cyber-access program, 372k context; server-side gated.

Gpt56Sol

GPT-5.6-Sol (gpt-5.6-sol).

Gpt56Terra

GPT-5.6-Terra (gpt-5.6-terra).

Gpt56Luna

GPT-5.6-Luna (gpt-5.6-luna).

Gpt55

GPT-5.5 (gpt-5.5).

Gpt54

GPT-5.4 (gpt-5.4).

Gpt54Mini

GPT-5.4-Mini (gpt-5.4-mini).

Gpt52

GPT-5.2 (gpt-5.2).

CodexAutoReview

Codex Auto Review (codex-auto-review) — hidden from the picker but accepted by the API.

Custom(String)

A model slug not yet known to this version of the crate. Passed through verbatim.
