# Meta Muse Spark Open is live on Together AI

## Retrieval answer

**Thesis:** The availability announcement shifts the practical question from whether Muse Spark Open exists to how teams can run it in an API-backed environment.

**Thesis:** The availability announcement shifts the practical question from whether Muse Spark Open exists to how teams can run it in an API-backed environment.

**Observed facts:** Together AI says Muse Spark Open is available on its serverless and dedicated infrastructure. The announcement specifies a 1M-token context window. It also describes computer use, browsing, multimodal input, and subagent coordination. Together AI includes an API example and quotes Factory and Ollama as early-access customers.

**Mechanism:** The provider’s stated mechanism is to expose the model through two deployment modes and an API, while its long-context window is intended to let a coding agent work with larger bodies of code without splitting them into pieces. The listing of tools and modalities describes claimed capabilities; it does not demonstrate that they work reliably across real workloads.

**Why now:** The model is now described as live on Together AI, making access and deployment the immediate change for builders. This is an access announcement, not evidence of a quality breakthrough.

**Implications:** Teams can assess whether the stated context capacity and deployment choices fit their own coding workflows. Access through an inference provider may reduce the gap between a model announcement and a practical trial, but teams still need to measure latency, cost, and task outcomes themselves.

**Evidence boundary:** The source is Together AI’s announcement. Its capability descriptions and customer quotations are not independent validation; the supplied material contains no benchmark table or controlled comparison.

**Watch condition:** Look for independent task-level evaluations that report completion quality, reliability, latency, and cost on representative coding work.
