Codex¶

Codex speaks the Responses API, which the server answers at /v1/responses.

npm install -g @openai/codex                       # install
superfluid launch codex --model unsloth/Qwen3.8-27B-GGUF:UD-Q4_K_M
superfluid launch codex -- exec "fix the failing test"

Aliases: codex-cli.

What launch gives it¶

given	what for
`-c` overrides	a `superfluid` provider: `base_url` the server's `/v1`, `wire_api = "responses"`, the key read from `SUPERFLUID_LAUNCH_KEY`; `web_search = "disabled"`, since the server runs function tools only
`-m <model>`	the served model
`$SUPERFLUID_HOME/launch/codex-models.json`	a one-model catalog (`model_catalog_json`) carrying the server's context window

Codex sends its sub-agent and MCP tools as namespace tools, which the Responses route flattens to namespace.member functions; see Responses API. The catalog names no freeform apply_patch tool, so Codex sends it as a function.
