ChatGPT-subscription allowlist hides gpt-6.1-terra #1623
Description
OAUTH_ALLOWED_MODELS in packages/opencode/src/plugin/codex.ts hides gpt-6.1-terra from ChatGPT Plus/Pro (OAuth) users.
Evidence (fetched 2026-10-29):
| id | Codex catalog (openai/codex codex-rs/models-manager/models.json on main) |
models.dev openai |
in allowlist |
|---|---|---|---|
gpt-6.1-terra |
added in openai/codex@126a0ee92e (2026-10-26, "Add GPT-6.1 Terra to model catalogs"); visibility: "list", priority 7, upgrade: null, minimal_client_version 0.153.0, plus/pro in available_in_plans |
present, release_date 2026-10-26 | no |
This id was added to the catalog after #1564 / #1565 were filed, so #1565 (which adds gpt-6-astra, gpt-6-luna, gpt-6-sol, gpt-6.1-sol) does not cover it.
Nothing allowlisted is retiring: every allowlisted id that appears in the catalog is visibility: "list" with retirement_at: null. gpt-5.3-codex-spark is not in the shipped catalog, but it never has been, and it was probed against the backend.
Not verified: gpt-6.1-terra has not been probed against POST https://chatgpt.com/backend-api/codex/responses.
