# Model API Versions

> Azure AI Model Inference API versions, deployment endpoint differences, and embedding endpoints.

### Azure AI Model Inference API

Azure AI uses the **Azure AI Model Inference API** exclusively. Legacy Azure OpenAI deployment endpoints (`/openai/deployments/{name}?api-version=XXX`) are no longer supported.

| API Version      | Endpoint Format                            | Usage                                                  |
| ---------------- | ------------------------------------------ | ------------------------------------------------------ |
| **v1** (default) | `{endpoint}/openai/v1`                     | Stable — model specified in the request body           |
| **preview**      | `{endpoint}/openai/v1?api-version=preview` | Preview features — model specified in the request body |

Key differences from the legacy Azure OpenAI format:

* **Model in body** — The model/deployment name is sent in the request body (`model` field), not in the URL path
* **No deployment URLs** — No `/openai/deployments/{name}` paths
* **No dated versions** — No `2024-10-21` or `2025-04-01-preview` style version strings
* **Authentication** — Uses `api-key` header (API key) or `Authorization: Bearer` (Managed Identity), same as before

### Embeddings

Text embedding models use `AzureOpenAIEmbeddings` from `@langchain/openai`, which still requires a dated API version (e.g., `2024-06-01`) for the Azure OpenAI Embeddings API. This is configured per embedding endpoint in **Admin → AI Search Endpoints** (\[`#/admin/search`]).
