Connect providers
Built-in default/* and fast/* models need no configuration. Use this page only when you want to bring your own upstream account or endpoint. In Connect → Upstream Providers, add a provider for each one you want your workspace to reach.
Provide:
- a stable provider code, used in targets such as
openai/gpt-5; - the provider base URL;
- its protocol style, such as Chat Completions or Responses;
- an upstream credential.
The platform supplies this credential when the deployed runtime calls the provider. Do not put provider secrets in model source, tool source, screenshots, or client applications.
Update a provider before deployment when a credential or endpoint changes. If you delete a provider, models that target its code stop working.
