Compare models

Three models answer the same prompt with the same MCP tools, side by side

Compare (top bar) sends every prompt to 2–4 lanes at once. Each lane uses a different model but the same workspace: same MCP servers, skills and system prompt β€” so the comparison is fair.

Per lane you get:

  • ⏱ total time and time-to-first-token
  • πŸͺ™ tokens used
  • πŸ”¨ number of tool calls
  • the full conversation, including tool calls and generative UI

Lanes keep their own history, so follow-up questions work. Change a lane’s model to reset it; Clear resets all lanes. Every run also appears in the inspector.

Typical uses: choosing a model for a use case, checking a cheaper model still calls tools correctly, or demoing the difference between a local and a frontier model.
