After months of rumors and anticipation, Meta officially unveiled its new AI model called Muse Spark<\/strong> \u2014 and the market reacted instantly: the company’s shares jumped more than 9% on the day of the announcement, April 8, 2026.<\/p>\n

This isn’t just another update. Muse Spark is a signal that Zuckerberg is serious about competing with OpenAI, Google, and Anthropic. And it looks like he has something to surprise us with. <\/p>\n

What Is Muse Spark and Who Created It<\/h2>\n

Muse Spark is the first product from the new Meta Superintelligence Labs (MSL)<\/strong>, led by Alexander Wang. The former founder and CEO of Scale AI joined Meta in June 2025 as part of a $14.3 billion deal. <\/p>\n

Development took exactly nine months. During this time, the team completely rewrote Meta’s entire AI stack from scratch \u2014 new architecture, new infrastructure, new data pipelines. Muse Spark is what came out of it. <\/p>\n

The model is the first in a new Muse<\/strong> series, where each generation will build on the previous one before larger versions are released.<\/p>\n

What Muse Spark Can Do \u2014 Three Operating Modes<\/h2>\n

\"Three<\/p>\n

The new model supports text, image, and voice queries simultaneously. Responses are text-only for now. <\/p>\n

Three Interaction Modes<\/h3>\n

Instant<\/strong> \u2014 for everyday queries. Fast and straightforward. <\/p>\n

Thinking<\/strong> \u2014 for more complex tasks requiring step-by-step reasoning.<\/p>\n

Contemplating<\/strong> \u2014 the most powerful mode. Multiple AI agents process the task in parallel and compete for the best answer. It’s in this mode that Muse Spark outperformed GPT-5.4 and Gemini 3.1 Pro on some tests. <\/p>\n

Where Muse Spark Is Strongest \u2014 Medicine<\/h2>\n

The most surprising result is in medical benchmarks. On the HealthBench Hard<\/strong> test, Muse Spark scored 42.8 points<\/strong>, leaving competitors far behind: <\/p>\n

\n\n\n\n\n\n\n\n\n
Model<\/th>\nHealthBench Hard<\/th>\n<\/tr>\n<\/thead>\n
Muse Spark<\/strong><\/td>\n42.8<\/strong><\/td>\n<\/tr>\n
GPT-5.4<\/td>\n40.1<\/td>\n<\/tr>\n
Grok 4.2<\/td>\n20.3<\/td>\n<\/tr>\n
Gemini 3.1 Pro<\/td>\n20.6<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Meta enlisted over 1,000 doctors<\/strong> to prepare medical training data. This isn’t a random result \u2014 it’s a strategic decision. <\/p>\n

Where It’s Available and How to Access It<\/h2>\n

Muse Spark is already live on meta.ai<\/strong> and in the Meta AI app. In the coming weeks, the model will appear in: <\/p>\n

    \n
  • Facebook<\/li>\n
  • Instagram<\/li>\n
  • WhatsApp<\/li>\n
  • Messenger<\/li>\n
  • Ray-Ban Meta smart glasses<\/li>\n<\/ul>\n

    For over 3 billion active users<\/strong> of Meta \u2014 it’s just an automatic app update. No separate registration required. <\/p>\n

    The End of Meta’s Open-Source Era<\/h2>\n

    This is probably the most important change that most news outlets are overlooking.<\/p>\n

    Meta’s previous Llama<\/strong> series models were fully open \u2014 they were downloaded over 1.2 billion times. Thousands of developers built products and startups on them. <\/p>\n

    Muse Spark is a closed commercial model.<\/strong> No open weights. No download option. No community forks. API access is currently limited to select partners only. <\/p>\n

    Meta promises to “possibly open-source in the future” \u2014 but without specific dates or commitments. The developer community is already reacting sharply: the r\/LocalLLaMA forum is filled with discontent. <\/p>\n

    Where Muse Spark Falls Short<\/h2>\n

    Being honest about weaknesses. According to the overall Artificial Analysis Intelligence Index<\/strong> ranking, the picture looks like this: <\/p>\n

    \n\n\n\n\n\n\n\n\n
    Model<\/th>\nOverall Rating<\/th>\n<\/tr>\n<\/thead>\n
    Gemini 3.1 Pro<\/td>\n57<\/td>\n<\/tr>\n
    GPT-5.4<\/td>\n57<\/td>\n<\/tr>\n
    Claude Opus 4.6<\/td>\n53<\/td>\n<\/tr>\n
    Muse Spark<\/strong><\/td>\n52<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

    In programming, Muse Spark lags significantly: on Terminal-Bench 2.0 it scored 59 points versus 75.1 for GPT-5.4. On the ARC-AGI-2 test, which checks unconventional thinking \u2014 only 42.5 versus 76+ for the leaders. <\/p>\n

    Meta itself doesn’t hide this \u2014 and surprisingly, it adds credibility to the announcement.<\/p>\n

    What This Means for You<\/h2>\n

    If you use WhatsApp, Instagram, or Facebook \u2014 in the coming weeks, the AI in these apps will become significantly smarter automatically. No action required on your part. <\/p>\n

    If you’re a developer \u2014 API access is currently limited, and an open version is uncertain.<\/p>\n

    If you follow the AI market \u2014 Meta is back in the game. And this means the competition between ChatGPT, Claude, Gemini, and now Muse Spark will only get fiercer. Which means models will get better and prices will drop. <\/p>\n
