## Usage

Worker - Streaming

```ts
export interface Env {
  AI: Ai;
}


export default {
  async fetch(request, env): Promise<Response> {


    const messages = [
      { role: "system", content: "You are a friendly assistant" },
      {
        role: "user",
        content: "What is the origin of the phrase Hello, World",
      },
    ];


    const stream = await env.AI.run("@cf/mistral/mistral-7b-instruct-v0.2-lora", {
      messages,
      stream: true,
    });


    return new Response(stream, {
      headers: { "content-type": "text/event-stream" },
    });
  },

## Parameters

\* indicates a required field

### Input

* `0` object

  * `prompt` string required min 1

    The input text prompt for the model to generate a response.

  * `lora` string

    Name of the LoRA (Low-Rank Adaptation) model to fine-tune the base model.

  * `response_format` object

    * `type` string

    * `json_schema`

  * `raw` boolean

    If true, a chat template is not applied and you must adhere to the specific model's expected formatting.

  * `stream` boolean

    If true, the response will be streamed back incrementally using SSE, Server Sent Events.

  * `max_tokens` integer default 256

    The maximum number of tokens to generate in the response.

  * `temperature` number default 0.6 min 0 max 5

    Controls the randomness of the output; higher values produce more random results.

  * `top_p` number min 0.001 max 1
