Meta is developing AI agents for personal and business use that will run continuously to help users achieve goals, CEO Mark Zuckerberg said during the company's Q1 2026 earnings call. The agents will build on Meta's newly-released Muse Spark model from Meta Superintelligence Labs.

Meta launched Muse Spark on April 8, 2026, a natively multimodal reasoning model with tool-use and visual chain-of-thought capabilities. Unlike Llama, it is entirely proprietary with no open weights. The model scores 52 on AI Index v4.0 and excels on health benchmarks but represents Meta's departure from its open-source identity.

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 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.

Meta Superintelligence Labs has launched Muse Spark, its first model since Mark Zuckerberg restructured the company's AI division. The multimodal model now powers Meta AI's app and website in the US, with rollout planned for WhatsApp, Instagram, Facebook, Messenger, and Meta's smart glasses in coming weeks.

Meta announced Muse Spark, its first major large language model since hiring Scale AI's Alexandr Wang nine months ago for a $14.3 billion deal. The proprietary model emphasizes efficiency and multimodal reasoning over top-tier performance, marking a strategic shift from Meta's previous open-source Llama approach. Muse Spark will power Meta's AI assistant across Facebook, Instagram, WhatsApp, Messenger, and Ray-Ban glasses starting in coming weeks.
