Meta launches Muse Spark 1.1, a low-cost agentic vision-language model with new paid API
Meta launched Muse Spark 1.1, a closed vision-language model optimized for agentic tasks including tool use, computer use, and multi-agent orchestration, alongside the Meta Model API — the company's first paid model access. The model ties GPT-5.6 Luna and GLM-5.2 on Artificial Analysis' Intelligence Index while offering substantially lower output token prices ($4.25/M vs. $25–$50/M for comparable closed models), and tops MCP Atlas and JobBench tool-use leaderboards. Meta's pricing strategy, subsidized by advertising revenue, is framed as a direct attack on competitors' API margins and could compress inference costs industry-wide.

Meta Superintelligence Labs releases Muse Spark 1.1, a multimodal agentic reasoning model with Meta Model API
Meta Superintelligence Labs has released Muse Spark 1.1, a significant upgrade to Muse Spark featuring a 1-million-token context window, strong agentic and computer-use capabilities, and major coding improvements on complex codebases. The model supports multi-agent orchestration, zero-shot generalization to MCP servers and custom tools, and multimodal reasoning including visual-to-code generation and video understanding. Alongside the model release, Meta is launching a public preview of the Meta Model API, giving developers programmatic access for the first time. Safety evaluations were conducted under Meta's Advanced AI Scaling Framework across frontier risk categories.
Meta Introduces Muse Spark: First Closed-Weights Model from Superintelligence Labs
Meta released Muse Spark, its first AI model in roughly a year and the debut product of its Superintelligence Labs, marking a significant departure from its open-weights Llama strategy. The natively multimodal reasoning model supports tool use and multi-agent orchestration, achieves fourth place on the Artificial Analysis Intelligence Index, and claims notable token efficiency—matching Llama 4 Maverick with over 10x less training compute. Meta withheld parameter count, architecture, and training details, positioning Muse Spark as a closed commercial product competing with OpenAI, Google, and Anthropic. The release introduces 'thought compression' via RL and a parallel multi-agent 'contemplating' mode, while showing gaps in coding and agentic benchmarks.
Meta Introduces Muse Spark: First Model from Meta Superintelligence Labs with Multimodal Reasoning and Multi-Agent Orchestration
Meta has launched Muse Spark, the first model from its newly formed Meta Superintelligence Labs, positioned as a natively multimodal reasoning model with tool-use, visual chain-of-thought, and multi-agent orchestration capabilities. The model introduces 'Contemplating mode,' which runs multiple agents in parallel to compete with frontier reasoning modes, achieving 58% on Humanity's Last Exam and 38% on FrontierScience Research. Meta claims a greater than 10x compute efficiency improvement over Llama 4 Maverick through a rebuilt pretraining stack, and describes predictable scaling across pretraining, RL, and test-time reasoning axes. Muse Spark is available at meta.ai with a private API preview, and is framed as the first step on a scaling ladder toward 'personal superintelligence.'
Meta Pivots to Closed Weights with Muse Spark; The Batch Issue 349 Roundup
Meta introduced Muse Spark, its first AI model in roughly a year and the first product from its Superintelligence Labs, marking a pivot away from its open-weights strategy toward a closed model. Muse Spark is a natively multimodal reasoning model supporting tool use and multi-agent orchestration, with three reasoning modes and a novel 'thought compression' post-training technique using RL to penalize excessive reasoning tokens. The model ranks fourth on the Artificial Analysis Intelligence Index and matches Llama 4 Maverick's capabilities with over an order of magnitude less training compute, though it trails in coding and agentic benchmarks. The issue also covers broader industry themes including AI-native software engineering team structures, big pharma AI adoption, and regulatory developments.
Meta Superintelligence Labs launches Muse Image and previews Muse Video with agentic generation capabilities
Meta Superintelligence Labs (MSL) has launched Muse Image, its most advanced image generation model, and previewed Muse Video, both representing the first media generation models from the newly formed lab. Muse Image operates as an agent with tool use (web search, code execution), emergent self-refinement, and test-time compute scaling, achieving a No. 2 Arena Elo ranking for text-to-image and editing tasks at launch. The model integrates with Muse Spark for joint agentic planning and is deploying across Meta AI, Instagram Stories, and WhatsApp. Muse Video, built on the same pretraining base, adds native audio support and is coming soon to creators.
Meta Publishes Advanced AI Scaling Framework and Safety & Preparedness Report for Muse Spark
Meta has released an updated Advanced AI Scaling Framework that expands risk evaluation categories—including chemical/biological threats, cybersecurity, and loss-of-control risks—and introduces formal Safety & Preparedness Reports tied to specific model deployments. The first such report covers Muse Spark, Meta's advanced reasoning model, detailing pre- and post-safeguard evaluations across severe risk categories and ideological balance. Meta also describes a shift in safety methodology: rather than scenario-specific refusal training, Muse Spark is trained on the reasoning behind safety principles, enabling more generalizable behavior in novel situations. The framework applies across open, API, and closed deployments.
Data Points: Apple sues OpenAI; Meta Muse Spark 1.1; ChatGPT Work; IBM CodeAlchemy; OpenAI Atlas shutdown
A multi-item digest covers five significant AI developments: Apple sued OpenAI alleging trade secret theft via former employees including hardware chief Tang Tan; Meta released Muse Spark 1.1, a multimodal agentic model with 1M-token context and strong tool-use capabilities; OpenAI launched ChatGPT Work, a cloud-based workplace agent competing with Anthropic's Claude Cowork; IBM released CodeAlchemy, a 500B+ token synthetic code dataset with execution traces showing smaller models trained on it outperform those trained on much larger real-code corpora; and OpenAI shut down its Atlas browser in favor of a Chrome extension and desktop integration. These items collectively reflect intensifying competition across agentic products, synthetic data strategies, and legal disputes between major AI players.
