| # Codex | |
| Codex uses the Responses API under `/v1`. Put this in `$CODEX_HOME/config.toml` (by default `~/.codex/config.toml`). `$LLMAO_KEY` is the personal access token from [My Keys](/keys). The model id comes from the [Models page](/models). This example uses `qwen3.8-27b`. | |
| ```toml | |
| model_provider = "llmao" | |
| model = "qwen3.8-27b" | |
| [model_providers.llmao] | |
| name = "llmao" | |
| base_url = "https://llm.apache.org/v1" | |
| env_key = "LLMAO_KEY" | |
| wire_api = "responses" | |
| ``` | |
| ```sh | |
| export LLMAO_KEY=<your personal access token> | |
| codex | |
| ``` | |
| `codex -m qwen3.8-27b` selects the model for one run. `wire_api` stays `responses`. |
