Mistral AI Integration

Connect Helicone with Mistral AI, a platform that provides state-of-the-art language models including Mistral-Large and Mistral-Medium for various AI applications.

You can follow their documentation here: https://docs.mistral.ai/

Gateway Integration

1. Create a Helicone account

   Log into helicone or create an account. Once you have an account, you can generate an API key.

2. Create a Mistral AI account

   Log into console.mistral.ai or create an account. Once you have an account, you can generate an API key from your dashboard.

3. Set HELICONE_API_KEY and MISTRAL_API_KEY as environment variable

   HELICONE_API_KEY=<your API key>
   MISTRAL_API_KEY=<your API key>
   

4. Modify the base URL and add Auth headers

   Replace the following Mistral AI URL with the Helicone Gateway URL:

   https://api.mistral.ai/v1/chat/completions -> https://mistral.helicone.ai/v1/chat/completions

   and then add the following authentication headers:

   Authorization: Bearer <your API key>
   

Now you can access all the models on Mistral AI with a simple fetch call:

Example

curl \
  --header 'Authorization: Bearer <MISTRAL_API_KEY>' \
  --header 'Content-Type: application/json' \
  --data '{
    "model": "mistral-large-latest",
    "messages": [{"role": "user", "content": "Say this is a test"}]
}' \
  --url https://mistral.helicone.ai/chat/completions

TypeScript Example

const httpClient = new HTTPClient();
httpClient.addHook("beforeRequest", async (req) => {
  req.headers.set("Helicone-Auth", `Bearer ${process.env.HELICONE_API_KEY}`);
});

const mistral = new Mistral({
  apiKey: process.env.MISTRAL_API_KEY,
  serverURL: "https://mistral.helicone.ai",
  httpClient,
});

async function run() {
  const result = await mistral.chat.complete({
    model: "mistral-small-latest",
    stream: false,
    messages: [
      {
        content:
          "Who is the best French painter? Answer in one short sentence.",
        role: "user",
      },
    ],
  });

  // Handle the result
  console.log(result);
}

run();
