Providers serving this model

Sorted by lowest combined prompt and completion price. Use "provider": {"sort": "throughput"} in the request body (or append :nitro to the model id) to route to the fastest provider instead.

Trust boundary: TR router attestation verifies the TrustedRouter gateway only. Provider policy separately describes the upstream model host's retention, confidential compute, and E2EE posture. Company country is separate from inference location. Weight formats are source-backed declarations, not per-request proofs.

Speed is the median (p50) from TR's recent measured requests for this exact model and provider, refreshed from the cached leaderboard. At least two timing samples are required; workload and network conditions affect results. Performance details

Questions

What model ID should I use for Muse Spark Open?

Use meta-models/muse-spark-open as the model field with the TrustedRouter OpenAI-compatible API. Credits routing and provider fallback happen behind that model ID.

Which providers serve Muse Spark Open?

TrustedRouter currently lists Nebius Token Factory, and Baseten for Muse Spark Open. Provider availability and routing eligibility can change as catalog and health data update.

How much does Muse Spark Open cost through TrustedRouter?

The current lowest Credits input price is $1.31875/1M and the lowest Credits output price is $4.48375/1M. Prices are per one million tokens and come from the current route catalog.

How do I require zero data retention for Muse Spark Open?

Set provider.min_privacy to zdr on the request. TrustedRouter considers only routes with a recorded zero-data-retention posture and fails closed if no eligible route remains.
