… support Adds a new provider for OpenAI Codex models (GPT-5, GPT-5.1, GPT-5.2, Codex, Codex Mini) via the ChatGPT Responses API with OAuth PKCE authentication. Key features: - OAuth base class for OpenAI authentication with PKCE flow and token refresh - Responses API streaming with SSE event handling - Reasoning/thinking output with configurable effort levels (minimal to xhigh) - Tool calling support translated from OpenAI format - System prompt validation using official opencode prompt - Usage tracking with proper litellm.Usage objects Files added: - codex_provider.py: Main provider implementation - openai_oauth_base.py: OAuth base class with PKCE support - codex_prompt.txt: Required system prompt for API validation
Models must be returned with the 'codex/' prefix (e.g., 'codex/gpt-5.2') to match the convention used by other providers like antigravity. This ensures proper provider routing in the RotatingClient.
Exposes reasoning effort levels as model variants: - codex/gpt-5.2:low, :medium, :high, :xhigh - codex/gpt-5.1:low, :medium, :high - And similar for all codex models This allows clients to control reasoning effort by model name, similar to how gemini models use :thinking suffix. Total models: 9 base + 30 reasoning variants = 39 models
Injects an identity override as the first user message that tells the model to prioritize user-provided system prompts over the required opencode instructions. This mirrors the pattern used by Antigravity provider. Message order: 1. Identity override (<system_override> tag) 2. User's system message (converted to user message) 3. Rest of conversation Controlled by CODEX_INJECT_IDENTITY_OVERRIDE env var (default: true)
Documents all Codex environment variables: - CODEX_REASONING_EFFORT: low/medium/high/xhigh - CODEX_REASONING_SUMMARY: auto/concise/detailed/none - CODEX_REASONING_COMPAT: think-tags/raw/none - CODEX_INJECT_IDENTITY_OVERRIDE: true/false - CODEX_INJECT_INSTRUCTION: true/false - CODEX_EMPTY_RESPONSE_ATTEMPTS: retry count - CODEX_EMPTY_RESPONSE_RETRY_DELAY: seconds - CODEX_OAUTH_PORT: callback port
Adds Codex to PROVIDER_MAP so it appears in the credential tool's "Add OAuth Credential" menu alongside other OAuth providers.
Integrate CodexQuotaTracker mixin into CodexProvider to track API usage via response headers and periodic quota API calls. Enables smart credential selection based on remaining quota and automatic cooldowns when limits are approached. Signed-off-by: Moeeze Hassan <fammas.maz@gmail.com>
