Muse Spark

Meta has added voice conversation capabilities and live camera analysis to its Meta AI app, both powered by the company's Muse Spark model. The features previously available only on Meta's AI glasses are now rolling out to the standalone app, which ranks fourth on the U.S. iPhone App Store.

Meta released Muse Spark in early April, its first closed-source AI model that will eventually offer paid developer access. According to Arena.AI rankings, Muse Spark trails Anthropic's Claude and Google's Gemini in text capabilities but beats OpenAI's GPT in vision tasks.

Meta has released Muse Spark, a proprietary AI model with restricted access via API and portal invite only—a striking reversal from CEO Mark Zuckerberg's 2024 manifesto championing open-source AI. The model claims performance matching top competitors from OpenAI, Anthropic, and Google, trained with an order of magnitude less compute than Llama 4.

Meta has released Muse Spark, the first model from Meta Superintelligence Labs, a unit assembled under chief AI officer Alexandr Wang following Meta's $14.3 billion investment in Scale AI. The natively multimodal model features a "Contemplating" reasoning mode with parallel sub-agents and marks Meta's break from its open-source Llama heritage by operating as closed source.
