V7 Go moved chats onto Go Agent V2, which carries a model picker and a reasoning setting so a lookup and a long analysis need not run the same way. GPT-6 Astra, Gemini 3.7 Flash and Gemini 3.8 Flash are selectable and Gemini 2.5 Pro is retired, and the settings tooltip now names the concrete model rather than a generic label. The same release keeps every turn of a run with each tool call stored beside the result it returned, attributes answers by the text they quote, and records an MCP tool invocation as user activity with the sign in route behind it.

Knowing exactly which model produced an extraction is where any validation record starts, and a platform that swaps models behind a generic label makes that impossible. Attributing a tool call back to a person is the other control a second line will ask for.
