Call Muse Spark 1.1 in one line

Muse Spark 1.1 speaks through the same OpenAI-compatible endpoint as every other model. Point your existing client at Final Router, set the model id, and you also get automatic fallback, spend caps and usage tracking - none of which the provider gives you directly.

Call Muse Spark 1.1
from openai import OpenAI

client = OpenAI(
    api_key="fr_live_...",                     # your Final Router key
    base_url="https://finalrouter.com/api/v1"  # the only line you change
)

resp = client.chat.completions.create(
    model="meta/muse-spark-1.1",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(resp.choices[0].message.content)

Data & residency

Served from the United States on the endpoint we call.

Training: not used to train the model. Retention: Standard tier is not used for training; their cheaper contributor tier is, and we do not use it.
