| Description | ChatGPT subscription access (Codex + GPT-5.3/5.4 family) via ChatGPT backend API |
| Provider Route on LiteLLM | `chatgpt/` |
| Supported Endpoints | `/responses`, `/chat/completions` (bridged to Responses for supported models) |
| 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-5.4`).

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.
