Playground

Open Inference → Playground. Playground supports Chat, Responses, Images, Audio, and other modes, with built-in samples for common LLM, reasoning, tool-call, and DashScope audio requests. It sends a probe for one selected Upstream Target straight to its upstream, so you can verify URLs, credentials, upstream model names, and request shape without using a customer sk-… on the normal billing path.

It does not write request logs, debit user budgets, or run Route Pool strategy, circuits, and failover. Validate the full behavior with real Proxy calls or Simulator. Call Agent Tools directly through /v1/tools/*.

When to use

After editing providers or routes, confirm upstream connectivity here before switching live traffic.

Select one route on the left, then load a Connectivity, Tool stream, or Reasoning sample in the request panel. The response appears below after Send.

How to use it

1. Open Playground.
2. Choose one route from the dropdown (icons indicate enabled vs disabled).
3. Choose Chat, Responses, Images, Audio, or another available mode and edit the request body; start from a connectivity, reasoning, tool-call, or DashScope audio template when helpful. For image generation, pick an OpenAI route with Images configured — see Image generation / edit.
4. Send and inspect status, errors, and body. Streaming requests expose event summaries, terminal state, and available usage; Gemini tool calls also summarize function names and arguments so incomplete streamed arguments are easier to spot.
5. Project-scoped Vertex AI routes use the same service-account parsing and OAuth access-token exchange as Proxy, making Playground suitable for validating the project ID and IAM access.

Validate synchronous DashScope multimodal ASR

For a route using the dashscope protocol and audio.transcriptions.multimodal operation, load the synchronous multimodal ASR template to check native DashScope JSON, the audio URL, upstream model name, and returned duration. The Gateway client endpoint is:

POST /v1/dashscope/services/aigc/multimodal-generation/generation

Playground checks only one Upstream Target. It does not debit user budget or create request logs. Use Simulator or a real client call to verify user auth, routing, and per-second billing.

Versus Simulator

Tool	Typical goal
Playground	Ops/dev: single Target → upstream wiring check
Simulator	Real sk-… from the browser to the Proxy — auth, routing, budget, logs
