## What the list means

This is the engine catalogue in this documentation edition. Availability in a workspace depends on the service configuration and plan. A catalogue entry is not a claim that every customer has every engine enabled.

## Search and model memory

Some engines use web search; others answer from model memory. The catalogue distinguishes model configurations. Google AI Overviews, AI Mode and Shopping are separate answer surfaces. Copilot is the Copilot assistant at copilot.microsoft.com, which answers from the Bing index.
