| Description | ChatGPT subscription access (Codex + GPT-5.3 family) via ChatGPT backend API |
| Provider Route on LiteLLM | `chatgpt/` |

| API Reference | https://chatgpt.com |
ChatGPT subscription access is native to the Responses API. Chat Completions requests are bridged to Responses for supported models (for example `chatgpt/gpt-5.2`).
ChatGPT subscription access is native to the Responses API. Chat Completions requests are bridged to Responses for supported models (for example `chatgpt/gpt-5.3-chat-latest`).
Notes:
- The ChatGPT subscription backend rejects token limit fields (`max_tokens`, `max_output_tokens`, `max_completion_tokens`) and `metadata`. LiteLLM strips these fields for this provider.
- `/v1/chat/completions` honors `stream`. When `stream` is false (default), LiteLLM aggregates the Responses stream into a single JSON response.
Common GPT-5.3 model IDs:
- `chatgpt/gpt-5.3-codex`
- `chatgpt/gpt-5.3-codex-spark`
- `chatgpt/gpt-5.3-chat-latest`
- `chatgpt/gpt-5.3-instant`
