Meta just dropped the first AI model from its Superintelligence Labs

Meta $META launched Muse Spark this week, the first large language model from Meta Superintelligence Labs, the AI division led by Chief AI Officer Alexandr Wang. The model now powers the Meta AI chatbot across the Meta AI app and meta.ai.

Executives describe Muse Spark as optimized for speed rather than scale, and it heads up what the company envisions as a broader "Muse" model family. Muse Spark marks a departure for Meta, which had previously built its AI identity around open-source Llama releases; the new model will be kept proprietary, with its architecture and code withheld from public access, Bloomberg reported. Meta said it is considering making the model available via API to select partners and hopes to open-source future versions.

During its nine-month development period, the project carried the internal codename Avocado, Bloomberg reported. According to Bloomberg, an unnamed Meta executive conceded capability gaps relative to rival products from OpenAI, Anthropic, and Google $GOOGL, framing the release with the quote: "an early data point on our trajectory." Coding was singled out as a relative weakness, while science, health, and math were cited as areas where the model performs well.

Training data for the model drew on a range of externally developed open-source systems, among them Alibaba's Qwen and offerings from OpenAI and Google. "Like others across the industry, Meta uses techniques like distillation with strict safeguards in place to learn from openly available AI models and improve our own," a Meta spokesperson said in a statement.

The model supports three reasoning levels: Instant, Thinking, and Contemplating modes. Meta AI can now launch multiple subagents in parallel to work on different parts of a query simultaneously. The company also built multimodal perception into the model, allowing Meta AI to process images alongside text — a capability Meta said will extend to its AI glasses.

Meta said the upgraded Meta AI experience is rolling out in the U.S. first, with expansion to more countries and to Instagram, Facebook, Messenger, WhatsApp, and its AI glasses in the coming weeks. Bloomberg reported that while no charges are currently attached to the Meta AI chatbot, paid subscription tiers are under consideration.

According to Bloomberg, an executive who declined to be named said the organization Wang leads has roughly 100 people reporting directly to him. Wang's arrival at Meta followed the company's $14 billion Scale AI deal, a move driven in part by Zuckerberg's dissatisfaction with how far Meta had fallen behind in the AI race. Meta has since committed between $115 billion and $135 billion in capital expenditures for 2026, with infrastructure costs as the primary driver.

Meta stock rose 6% following the announcement.
