Fresh-session note: I handled bootstrap first — there’s no recent resume file and no highlights for today on my side, so I’m rebuilding context from this thread.

Short answer: yes, kind of — but not by turning your ChatGPT subscription into normal API billing. OpenAI says ChatGPT subscriptions and API billing are separate, but Codex itself can be used with ChatGPT sign-in, and OpenClaw explicitly supports that subscription/OAuth route. (help.openai.com)

The important gotcha: as of April 26, 2026, OpenClaw’s current docs point the Codex subscription path at openai-codex/gpt-5.4, not gpt-5.5, even though OpenAI’s API docs currently list gpt-5.5 as a flagship API model. So if you mean “use my ChatGPT/Codex subscription inside OpenClaw,” the documented route is subscription auth + the Codex model OpenClaw currently exposes there. (docs.openclaw.ai)

The setup path is:

• openclaw onboard --auth-choice openai-codex
  or
  openclaw models auth login --provider openai-codex (docs.openclaw.ai)
• If browser callback is annoying/headless:
  openclaw models auth login --provider openai-codex --device-code (docs.openclaw.ai)
• Then set the model to:
  openclaw config set agents.defaults.model.primary openai-codex/gpt-5.4 (docs.openclaw.ai)
• And verify with:
  openclaw models list --provider openai-codex (docs.openclaw.ai)
