# Mistral AI Provider

The [Mistral AI](https://mistral.ai/) provider contains language model support for the Mistral chat API.

## Setup

The Mistral provider is available in the `@ai-sdk/mistral` module. You can install it with

<Tabs items={['pnpm', 'npm', 'yarn', 'bun']}>
  <Tab>
    <Snippet text="pnpm add @ai-sdk/mistral" dark />
  </Tab>
  <Tab>
    <Snippet text="npm install @ai-sdk/mistral" dark />
  </Tab>
  <Tab>
    <Snippet text="yarn add @ai-sdk/mistral" dark />
  </Tab>

  <Tab>
    <Snippet text="bun add @ai-sdk/mistral" dark />
  </Tab>
</Tabs>

## Provider Instance

You can import the default provider instance `mistral` from `@ai-sdk/mistral`:

```ts
import { mistral } from '@ai-sdk/mistral';
```

If you need a customized setup, you can import `createMistral` from `@ai-sdk/mistral`
and create a provider instance with your settings:

```ts
import { createMistral } from '@ai-sdk/mistral';

const mistral = createMistral({
  // custom settings
});
```

You can use the following optional settings to customize the Mistral provider instance:

- **baseURL** _string_

  Use a different URL prefix for API calls, e.g. to use proxy servers.
  The default prefix is `https://api.mistral.ai/v1`.

- **apiKey** _string_

  API key that is being sent using the `Authorization` header.
  It defaults to the `MISTRAL_API_KEY` environment variable.

- **headers** _Record&lt;string,string&gt;_

  Custom headers to include in the requests.

- **fetch** _(input: RequestInfo, init?: RequestInit) => Promise&lt;Response&gt;_

  Custom [fetch](https://developer.mozilla.org/en-US/docs/Web/API/fetch) implementation.
  Defaults to the global `fetch` function.
  You can use it as a middleware to intercept requests,
  or to provide a custom fetch implementation for e.g. testing.

## Language Models

You can create models that call the [Mistral chat API](https://docs.mistral.ai/api/#operation/createChatCompletion) using a provider instance.
The first argument is the model id, e.g. `mistral-large-latest`.
Some Mistral chat models support tool calls.

```ts
const model = mistral('mistral-large-latest');
```

Mistral chat models also support additional model settings that are not part of the [standard call settings](/docs/ai-sdk-core/settings).
You can pass them as an options argument and utilize `MistralLanguageModelOptions` for typing:

```ts
import { mistral, type MistralLanguageModelOptions } from '@ai-sdk/mistral';
const model = mistral('mistral-large-latest');

await generateText({
  model,
  providerOptions: {
    mistral: {
      safePrompt: true, // optional safety prompt injection
      parallelToolCalls: false, // disable parallel tool calls (one tool per response)
    } satisfies MistralLanguageModelOptions,
  },
});
```

The following optional provider options are available for Mistral models:

- **safePrompt** _boolean_

  Whether to inject a safety prompt before all conversations.

  Defaults to `false`.

- **documentImageLimit** _number_

  Maximum number of images to process in a document.

- **documentPageLimit** _number_

  Maximum number of pages to process in a document.

- **strictJsonSchema** _boolean_

  Whether to use strict JSON schema validation for structured outputs. Only applies when a schema is provided and only sets the [`strict` flag](https://docs.mistral.ai/api/#tag/chat/operation/chat_completion_v1_chat_completions_post) in addition to using [Custom Structured Outputs](https://docs.mistral.ai/capabilities/structured-output/custom_structured_output/), which is used by default if a schema is provided.

  Defaults to `false`.

- **structuredOutputs** _boolean_

  Whether to use [structured outputs](#structured-outputs). When enabled, tool calls and object generation will be strict and follow the provided schema.

  Defaults to `true`.

- **parallelToolCalls** _boolean_

  Whether to enable parallel function calling during tool use. When set to false, the model will use at most one tool per response.

  Defaults to `true`.

### Document OCR

Mistral chat models support document OCR for PDF files.
You can optionally set image and page limits using the provider options.

```ts
const result = await generateText({
  model: mistral('mistral-small-latest'),
  messages: [
    {
      role: 'user',
      content: [
        {
          type: 'text',
          text: 'What is an embedding model according to this document?',
        },
        {
          type: 'file',
          data: new URL(
            'https://github.com/vercel/ai/blob/main/examples/ai-core/data/ai.pdf?raw=true',
          ),
          mediaType: 'application/pdf',
        },
      ],
    },
  ],
  // optional settings:
  providerOptions: {
    mistral: {
      documentImageLimit: 8,
      documentPageLimit: 64,
    },
  },
});
```

### Reasoning Models

Mistral offers reasoning models that provide step-by-step thinking capabilities:

- **magistral-small-2506**: Smaller reasoning model for efficient step-by-step thinking
- **magistral-medium-2506**: More powerful reasoning model balancing performance and cost

These models return content that includes `<think>...</think>` tags containing the reasoning process. To properly extract and separate the reasoning from the final answer, use the [extract reasoning middleware](/docs/reference/ai-sdk-core/extract-reasoning-middleware):

```ts
import { mistral } from '@ai-sdk/mistral';
import {
  extractReasoningMiddleware,
  generateText,
  wrapLanguageModel,
} from 'ai';

const result = await generateText({
  model: wrapLanguageModel({
    model: mistral('magistral-small-2506'),
    middleware: extractReasoningMiddleware({
      tagName: 'think',
    }),
  }),
  prompt: 'What is 15 * 24?',
});

console.log('REASONING:', result.reasoningText);
// Output: "Let me calculate this step by step..."

console.log('ANSWER:', result.text);
// Output: "360"
```

The middleware automatically parses the `<think>` tags and provides separate `reasoningText` and `text` properties in the result.

### Example

You can use Mistral language models to generate text with the `generateText` function:

```ts
import { mistral } from '@ai-sdk/mistral';
import { generateText } from 'ai';

const { text } = await generateText({
  model: mistral('mistral-large-latest'),
  prompt: 'Write a vegetarian lasagna recipe for 4 people.',
});
```

Mistral language models can also be used in the `streamText`, `generateObject`, and `streamObject` functions
(see [AI SDK Core](/docs/ai-sdk-core)).

#### Structured Outputs

Mistral chat models support structured outputs using JSON Schema. You can use `generateObject` or `streamObject`
with Zod, Valibot, or raw JSON Schema. The SDK sends your schema via Mistral's `response_format: { type: 'json_schema' }`.

```ts
import { mistral } from '@ai-sdk/mistral';
import { generateObject } from 'ai';
import { z } from 'zod';

const result = await generateObject({
  model: mistral('mistral-large-latest'),
  schema: z.object({
    recipe: z.object({
      name: z.string(),
      ingredients: z.array(z.string()),
      instructions: z.array(z.string()),
    }),
  }),
  prompt: 'Generate a simple pasta recipe.',
});

console.log(JSON.stringify(result.object, null, 2));
```

You can enable strict JSON Schema validation using a provider option:

```ts highlight="7-11"
import { mistral } from '@ai-sdk/mistral';
import { generateObject } from 'ai';
import { z } from 'zod';

const result = await generateObject({
  model: mistral('mistral-large-latest'),
  providerOptions: {
    mistral: {
      strictJsonSchema: true, // reject outputs that don't strictly match the schema
    },
  },
  schema: z.object({
    title: z.string(),
    items: z.array(z.object({ id: z.string(), qty: z.number().int().min(1) })),
  }),
  prompt: 'Generate a small shopping list.',
});
```

<Note>
  When using structured outputs, the SDK no longer injects an extra "answer with
  JSON" instruction. It relies on Mistral's native `json_schema`/`json_object`
  response formats instead. You can customize the schema name/description via
  the standard structured-output APIs.

<Note>
  The table above lists popular models. Please see the [Mistral
  docs](https://docs.mistral.ai/getting-started/models/models_overview/) for a
  full list of available models. The table above lists popular models. You can
  also pass any available provider model ID as a string if needed.
</Note>

## Embedding Models

You can create models that call the [Mistral embeddings API](https://docs.mistral.ai/api/#operation/createEmbedding)
using the `.textEmbedding()` factory method.

```ts
const model = mistral.textEmbedding('mistral-embed');
```

You can use Mistral embedding models to generate embeddings with the `embed` function:

```ts
import { mistral } from '@ai-sdk/mistral';
import { embed } from 'ai';

const { embedding } = await embed({
  model: mistral.textEmbedding('mistral-embed'),
  value: 'sunny day at the beach',
});
```
