Meta Just Launched Muse Spark — Its First Closed AI Model And A Huge Break From Llama

TamilTech AI summary

Meta just launched Muse Spark, its first major closed-source AI model and a clear break from years of open Llama releases you could download and fine-tune yourself. The model comes from the new Meta Superintelligence Labs led by Alexandr Wang (ex-Scale AI), and you can use it on meta.ai and the Meta AI app—but not run the weights on your own machines. It stands out for native multimodal reasoning, multi-agent task orchestration, visual chain-of-thought sketches, and health features tuned with over 1,000 physicians, plus Instant and Thinking modes (with a deeper Contemplating mode planned). The bigger story for many users is distribution: Meta plans to roll it into Facebook, Instagram, and especially WhatsApp, which could put frontier AI in front of hundreds of millions of people with almost no setup. Meta is going closed for competitive, safety/liability, and monetization reasons, so watch for the WhatsApp rollout even if full benchmark comparisons are still light.
