Connect a personal ChatGPT plan as a model provider

ChatGPT now appears in the provider grid. Open Models > Providers > Connect provider > ChatGPT > Sign in with ChatGPT, approve plan use in ChatGPT, and return to Everruns. The connection belongs to you, not the organization: its models are available only to you, and the detail page shows account status, quota guidance, and reconnect and disconnect controls.
Self-hosted deployments use OpenAI’s Sign in with ChatGPT for open-source
applications. The ChatGPT plan transport is now part of everruns-drivers.
