Meta drops Muse Spark multimodal model

Muse Spark represents a pivotal change in Meta's AI strategy, prioritizing reasoning and native multimodality over the open-weights legacy of the Llama series.

• –First model in the "Muse" series, designed for high-level reasoning and native multimodal perception across text, vision, and audio.
• –Introduces "Thinking" and "Contemplating" modes, directly challenging high-reasoning models like Gemini Deep Think and GPT Pro.
• –Proprietary weights signal a shift away from the open-source ethos that defined Meta's Llama era, potentially to protect competitive reasoning moats.
• –Deep integration into Meta's consumer apps with specialized "Shopping" and "Health" optimizations points to a product-first rollout.
• –While Meta claims parity with "Llama 4 Maverick" at lower compute, early community sentiment remains skeptical about its true state-of-the-art standing.
