Tick above each rail is this model, below it the other 65. Dashed rule is the field median, solid is its best. Better is left; the axis stops at the 90th percentile, so a few models sit past its right edge.

FAQ

Common questions about this model.

What is the context window of Muse Spark 1.2?

Muse Spark 1.2 has a 1M-token context window — roughly 1542 pages of text in a single request.

How much does the Muse Spark 1.2 API cost?

$1.688 per 1M input tokens and $5.738 per 1M output tokens. No subscription; you pay only for what you use.

Does Muse Spark 1.2 support function calling?

Yes — Muse Spark 1.2 supports tool/function calling and structured outputs (JSON mode), so it works with agent frameworks out of the box.

Are the weights for Muse Spark 1.2 publicly available?

No. Meta does not publish Muse Spark 1.2's weights — it is reachable through an API rather than as a file you can download and run (https://about.fb.com/news/2026/04/introducing-muse-spark-meta-superintelligence-labs/, read 2026-08-31). That is Meta's decision about their own product, not a limitation of Kyma.

Is Muse Spark 1.2 ever served below the precision its creator released it at?

Kyma cannot say, and for this model nobody can. Meta does not publish Muse Spark 1.2's weights, so there is no released checkpoint whose precision a route could be measured against. We publish "not established" rather than reading a low format as a downgrade: on several models in this catalogue a low format is exactly how the creator ships it.

How do I use Muse Spark 1.2?

Kyma is OpenAI-compatible: point your SDK's base URL at https://kymaapi.com/v1, use your Kyma API key, and set the model to muse-spark-1.2. Signing up is free and includes $0.50 of credit — no card required.
