Muse Spark 1.2 · orcarouter

Muse Spark 1.2 is Meta's reasoning model for complex agentic tasks, and the current checkpoint of the Muse Spark family. Meta describes it as an updated checkpoint over Muse Spark 1.1 with slightly higher performance, served on the same Standard tier at identical pricing — a drop-in upgrade rather than a new tier. It accepts an unusually broad input surface — text, images, video, audio, and PDF documents — and returns text, reasoning natively across modalities within a 1M-token context window. It supports configurable reasoning effort, native tool calling, and structured outputs, making it well suited for multimodal agents, deep research over mixed media, and long-context analysis. Muse Spark 1.2 targets workloads that combine documents, screenshots, recordings, and video with text — from analyzing long reports and media libraries to driving multi-step agentic pipelines that must reason over more than just text. Meta also ships muse-spark-1.2-contributor, the same checkpoint on its Contributor tier.
