Meta's first closed-source AI model with planned paid developer access, marking a strategic shift from the open-source Llama series. Released from Meta Superintelligence Labs under new AI leadership.
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's AI app surged from No. 57 to No. 5 on the U.S. App Store within 24 hours of launching Muse Spark, Meta's new multimodal AI model. The model accepts voice, text, and image inputs and features reasoning capabilities for science and math tasks, visual coding, and multi-agent functionality.
Meta released Muse Spark this week, its first major new AI model in over a year, marking a strategic shift from open-source Llama models to proprietary technology. The release comes nearly 10 months after Meta spent over $14 billion to hire Scale AI co-founder Alexandr Wang and establish Meta Superintelligence Labs. The critical question remains how Meta will monetize the model and compete with established rivals OpenAI, Anthropic, and Google.
Meta announced Muse Spark today, its first model release since Llama 4 a year ago. The hosted model is available in private API preview and on meta.ai with Instant and Thinking modes, benchmarking competitively against Anthropic's Opus 4.6 and Google's Gemini 3.1 Pro, though behind on Terminal-Bench 2.0.
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.
Meta Superintelligence Labs has launched Muse Spark, a native multimodal reasoning model that scores 52 on the Artificial Analysis Intelligence Index, placing it in the top 5 frontier models. This marks Meta's first frontier-class model and its first AI system without open weights, representing a strategic shift from its open-source Llama strategy. The model achieves comparable efficiency to Gemini 3.1 Pro while matching Llama 4 Maverick capabilities with over an order of magnitude less compute.
Meta has discontinued its Llama model line and launched Muse Spark as the foundation of its new AI strategy under Meta Superintelligence Labs. The model features a Contemplating mode for complex reasoning tasks and specializes in multimodal perception, health applications, and agentic tasks. Muse Spark is available today in Meta AI apps, with a private API preview for select partners.
