# Answers

> Language models that reason over workspace knowledge

**Answer** models handle natural-language queries over already ingested workspace data. They call workspace tools and reply with reasoning over that layer, not a generic model call on the raw file.

They serve queries on the [Middleware API](/products/middleware) and Explore in [Observatory](/products/observatory). Retrieval uses [embeddings](/products/models-embeddings).

## Configuration

Callers set these on a query. AiQL selects the checkpoint behind each mode.

| Setting     | How it is configured                                                                                              |
| ----------- | ----------------------------------------------------------------------------------------------------------------- |
| Ask         | Default mode. Direct answers over workspace knowledge.                                                            |
| Reason      | Higher-effort reasoning. Used when the question needs a longer chain.                                             |
| Build       | Authoring mode. Used when the query should produce or extend a work product.                                      |
| Visualize   | Optional. Exposes graph visualization tools in the same turn.                                                     |
| Interactive | Optional. Exposes follow-up questions in the same turn.                                                           |
| Tools       | The model may search knowledge, inspect sources, and navigate related records. It does not replace Studio review. |
