Meta Launches Muse Spark 1.1 With 1 Million-Token Context and Public API Preview

Summary
Muse Spark 1.1 is now live in the Meta AI app, on meta.ai, and through a new public-preview Meta Model API for developers.
The upgraded multimodal model targets agentic work, with Meta highlighting stronger tool and computer use, coding, and multimodal reasoning than the original Muse Spark.
A 1 million-token context window underpins those gains, letting the model manage long workflows, delegate tasks across subagents, and retain earlier steps in extended sessions.
Meta said internal and safety evaluations showed improved coding performance, lower hallucination and sycophancy rates, and safe margins across chemical, cyber, and loss-of-control risk categories.
The release, alongside this week's Muse Image launch, advances Meta's push toward personal superintelligence and a stronger position in AI coding against OpenAI and Anthropic.
