# Responses

## Overview

Stateless Responses API for text, images, reasoning, function calls, and streaming.

### Available Operations

* [create](#create) - Create Response
* [countInputTokens](#countinputtokens) - Count Input Tokens

## create

Create a response.

Generate a model response from text or image inputs. The response can
include text, reasoning, and function calls. Set stream to true to
receive Server-Sent Events.

For multi-turn conversations, send the full history in input, including
prior output items and function results. Responses are not stored. Only
client-executed function tools are supported.

### Example Usage

<!-- UsageSnippet language="typescript" operationID="create_response_v1_responses_post" method="post" path="/v1/responses" -->
```typescript
import { Mistral } from "@mistralai/mistralai";

const mistral = new Mistral({
  apiKey: process.env["MISTRAL_API_KEY"] ?? "",
});

async function run() {
  const result = await mistral.responses.create({
    model: "V90",
    input: [],
  });

  console.log(result);
}

run();
```

### Standalone function

The standalone function version of this method:

```typescript
import { MistralCore } from "@mistralai/mistralai/core.js";
import { responsesCreate } from "@mistralai/mistralai/funcs/responsesCreate.js";

// Use `MistralCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const mistral = new MistralCore({
  apiKey: process.env["MISTRAL_API_KEY"] ?? "",
});

async function run() {
  const res = await responsesCreate(mistral, {
    model: "V90",
    input: [],
  });
  if (res.ok) {
    const { value: result } = res;
    console.log(result);
  } else {
    console.log("responsesCreate failed:", res.error);
  }
}

run();
```

## countInputTokens

Count response input tokens.

Count the input tokens for a Responses request without generating a
response. The count includes the supplied conversation, instructions,
and tool definitions.

Use the same input, instructions, and tools that you plan to send when
creating a response. For multi-turn conversations, include prior output
items and function results in input.

### Example Usage

<!-- UsageSnippet language="typescript" operationID="count_input_tokens_v1_responses_input_tokens_post" method="post" path="/v1/responses/input_tokens" -->
```typescript
import { Mistral } from "@mistralai/mistralai";

const mistral = new Mistral({
  apiKey: process.env["MISTRAL_API_KEY"] ?? "",
});

async function run() {
  const result = await mistral.responses.countInputTokens({
    model: "Corvette",
    input: "<value>",
  });

  console.log(result);
}

run();
```
