Completes the in-progress OpenAI Codex provider and bumps the workspace to
0.8.55. Builds on the committed Together AI provider + model catalog work.
OpenAI Codex (ChatGPT) provider — experimental:
- Wire the previously-dead OAuth module into credential resolution. The TUI
config now resolves the access token via the Codex CLI login in
~/.codex/auth.json (env overrides OPENAI_CODEX_ACCESS_TOKEN/CODEX_ACCESS_TOKEN),
refreshing expired tokens synchronously via the OpenAI token endpoint —
mirroring the existing Kimi OAuth flow rather than introducing a new pattern.
- Send the ChatGPT backend's required headers from the Responses client
(chatgpt-account-id, OpenAI-Beta: responses=experimental, originator) and
stop duplicating the Authorization header already installed on the client.
- Fix the cli crate's non-exhaustive ProviderKind matches (compile blocker).
Consistency / de-slop pass (so the provider fits the whole app, not one path):
- has_api_key_for / active_provider_has_config_api_key now detect the Codex
OAuth login on disk, the same way they detect Kimi OAuth — a `codex login`
user is no longer reported as unauthenticated.
- Replace the bogus OPENAI_CODEX_API_KEY hint (which exists nowhere else) with
the real OPENAI_CODEX_ACCESS_TOKEN/CODEX_ACCESS_TOKEN in the auth-error and
picker surfaces.
- Drop dead state in the Responses stream parser (unused ToolCallState fields /
imports); tool-call data is streamed live.
- Update docs/PROVIDERS.md, config.example.toml, and the provider-metadata wire
test for the Responses wire format.
Release:
- Bump workspace + crates + npm package to 0.8.55; update CHANGELOG.md and
crates/tui/CHANGELOG.md.
Note: the live Responses round-trip has not been exercised against the
production ChatGPT backend in this environment; the provider ships as preview.
