Muse Spark 1.1

Meta
Verdict

A versatile model, balanced across most use cases.

Overview

Muse Spark 1.1 is Meta's proprietary model built for agent orchestration and multimodal workflows, offering a one-million-token context window at a competitive price ($1.25/$4.25 per million tokens). No benchmarks accompany this release, making independent performance assessment impossible for now. The model stays closed and API-only, with no on-premise option for European organisations concerned about data residency and sovereignty.

    What the vendor offers and documents for professional use in Europe. An undocumented criterion counts as zero and stays visible: the score rises when the vendor publishes, not when we assume.
