How to use Muse Spark 1.1 API

Install any OpenAI-compatible SDK, point it at api.aimlapi.com/v1, and set the model to meta/muse-spark-1.1.

from openai import OpenAI

client = OpenAI(
   base_url="https://api.aimlapi.com/v1",
   api_key="<YOUR_AIMLAPI_KEY>",
)

response = client.chat.completions.create(
   model="meta/muse-spark-1.1",
   messages=[
       {"role": "system", "content": "You are a helpful assistant."},
       {"role": "user", "content": "What can Muse Spark 1.1 do?"},
   ],
)

print(response.choices[0].message.content)

import OpenAI from "openai";

const client = new OpenAI({
 baseURL: "https://api.aimlapi.com/v1",
 apiKey: "<YOUR_AIMLAPI_KEY>",
});

const response = await client.chat.completions.create({
 model: "meta/muse-spark-1.1",
 messages: [
   { role: "system", content: "You are a helpful assistant." },
   { role: "user", content: "What can Muse Spark 1.1 do?" },
 ],
});

console.log(response.choices[0].message.content);

curl https://api.aimlapi.com/v1/chat/completions \
 -H "Authorization: Bearer <YOUR_AIMLAPI_KEY>" \
 -H "Content-Type: application/json" \
 -d '{
   "model": "meta/muse-spark-1.1",
   "messages": [
     {"role": "system", "content": "You are a helpful assistant."},
     {"role": "user", "content": "What can Muse Spark 1.1 do?"}
   ]
 }'

OpenAI-compatible — swap the base URL and it works with your existing SDK.
