# Corvic Models

> Jackdaw, Rook, and Raven: three tiers tuned for data analysis, plus Auto, which picks the tier for each message.

Corvic models are tiers, not single models. Each tier runs a list of strong underlying models at one flat price, so you pick the quality and cost you want rather than a vendor. If a model in the tier fails to start or refuses a request, Corvic moves on to the next one in the same tier.

| Model | Best for | API ID |
| - | - | - |
| **Jackdaw** | Cost-optimized for everyday data analysis | `corvic/jackdaw` |
| **Rook** | Balanced quality, speed, and cost for data analysis. The default for agents. | `corvic/rook` |
| **Raven** | Highest quality for complex data analysis, at a higher price | `corvic/raven` |
| **Web Augment** | Answers each row from the live web, billed per answer | `corvic/web-augment` |

Responses name only the Corvic model. The underlying vendor model isn't disclosed.

## Auto

**Auto** (shown as *Adaptive*, for example **Rook · Adaptive**) starts on the agent's chosen tier and adjusts as the conversation goes:

* It **moves down** to Jackdaw for quick replies.
* It **moves up** when a conversation struggles: after you push back, after tools fail, or for a harder request.
* It picks the tier for tasks the agent delegates.

When Auto changes tier, the reply says so, for example *Auto moved up to Raven after your feedback*.

> [!NOTE]
>
> Auto needs the conversation's history, so it's available in Corvic chats and agents but not through the API. Over the API, call a tier directly.

## Choose a model

Pick the model in an agent's settings or in the chat's model picker. To use a Corvic model from your own code, see the [API Playground](https://docs.corvic.ai/models/api-playground.md).
