The Playground page (/admin/dashboard/playground) sends requests through the gateway’s public API with your dashboard key, so every call is routed, logged, and metered exactly like a client’s request. Pick an endpoint (/v1/chat/completions, /v1/responses, or /v1/messages), a model from the inventory or any alias, or virtual model by name, and whether to stream; build the conversation from editable, reorderable System, User, and Assistant messages; and send a prompt. The JSON panel on the right shows the request body as it will be sent (updated live as you edit) and the last response with its status, latency, and token usage — streamed responses are assembled into the same shape a non-streaming call returns. Requests are subject to the same budgets, rate limits, guardrails, and audit logging as any other client of the gateway.

User path scoping

Virtual models can be restricted to specific user_paths, and Playground requests authenticated with the master key can scope themselves to one of those paths with the User path field next to the model picker. When you select a model whose policy declares user_paths, the field is prefilled with the first entry; you can edit it before sending. On send, the value is carried on the X-GoModel-User-Path request header, exactly as an external client would send it, so the gateway records the path on the request snapshot and grants access to models restricted to that path — a request without the header is denied for those models. Note: the dashboard always sends the default X-GoModel-User-Path header name. If you customize the header through the USER_PATH_HEADER server configuration, the dashboard does not pick that up, and Playground requests stop carrying the scoped path.
