Open **Playground** from the console. Select a model in each panel, enter a system prompt, and send the same request through both panels.

The Playground lets you compare Raw mode with SERV Reasoning and inspect outputs, reasoning, token usage, cost, and latency. It also supports text, image, and file prompts.

Compare a larger model in Raw mode with a smaller model using SERV. Repeat with representative production prompts, edge cases, and incomplete inputs.
