# Providers and vendors

> How the generated catalog maps public model IDs to provider adapters.

The generated catalog is the source of truth for provider rows. Docs can name the adapter families, but the catalog decides what is available in a build.

Use:

```http theme={null}
GET /v1/models
POST /v1/models/search
```

Each model row includes a provider and public model ID. The engine resolves that row, computes the provider wire model with `upstreamModelId ?? modelId`, and calls the matching adapter.

## Adapter families

The API includes adapters for providers and OpenAI-compatible families such as:

| Provider or family             | Used for                                                                |
| ------------------------------ | ----------------------------------------------------------------------- |
| OpenAI                         | Chat, responses, embeddings, images, audio, video.                      |
| Azure OpenAI                   | Chat, embeddings, images.                                               |
| Gemini and Vertex              | Text, embeddings, images, speech, video, native Google wire formats.    |
| Alibaba                        | Text, embeddings, images, speech, transcription, video.                 |
| Cloudflare                     | Workers AI model rows, including text, image, speech, transcription.    |
| Fireworks                      | OpenAI-compatible text and selected media routes.                       |
| ASI Cloud                      | OpenAI-compatible text rows.                                            |
| Deepgram, ElevenLabs, Cartesia | Speech and transcription.                                               |
| Roboflow                       | Vision and computer-vision outputs such as detections and segmentation. |

Provider support comes from source data and adapter code. If the catalog row exists and the adapter supports that modality, the route can execute it.
