codex) is OpenAI’s agentic coding CLI. It authenticates with an
OpenAI API key.
Set it up
1
Open Admin → Agent LLM
Scroll to the per-agent keys section.
2
Add the OpenAI key (Codex)
Paste your OpenAI API key. It’s write-only and encrypted at rest, and only needed if you
enable the Codex agent.
3
(Optional) allow specific models
Set a Codex model allowlist (e.g.
gpt-5, gpt-5-mini). With two or more, the New Task form
shows a Model dropdown for Codex tasks.Using it in a task
Pick Codex CLI as the agent in the New Task form. If a Codex model allowlist is set, choose the model per task.An org’s Agent allowlist controls which CLIs users may launch. If Codex isn’t in the
allowlist, it won’t appear in the New Task dropdown.
Through the internal gateway
If your org routes everything through the internal gateway, Codex traffic goes through it too. Codex uses the OpenAI SDK, so the gateway path for Codex is the origin plus/v1 — this is derived automatically from your
single gateway endpoint; you don’t configure it separately. A per-agent key is
only needed if your gateway issues a different key per model family.
