Dead on Wednesday It announced its first major model since CEO Mark Zuckerberg rebooted the company’s AI efforts last year under a new division called Meta-intelligence laboratories. The model, called Muse Spark, is a step toward Zuckerberg’s vision of “personal superintelligence,” the company says, and for now, it will remain closed source.
Zuckerberg said in a social media post mail Meta’s goal is to build AI products that “don’t just answer your questions, but act as agents that do things for you.” The billionaire added that he is “optimistic that this will support a wave of creativity, entrepreneurship, growth and health.”
The Muse Spark certainly looks like a big upgrade over the last big Meta release, Llama 4, which released in April 2025 and was seen in the tech industry as a disappointment due to mediocre performance.
Meta makes Muse Spark available via meta.ai and through the Meta AI app. Unlike Llama, Muse Spark isn’t released for others to download, though the company says it hopes to unlock future releases. Meta was previously seen as a leader in open source AI, and has made its Llama models available for researchers, startups, and hobbyists to download and customize.
“Looking to the future, we plan to launch increasingly advanced models that push the boundaries of intelligence and capabilities, including new open source models,” Zuckerberg wrote.
Meta’s self-reported benchmark scores for Muse Spark indicate that the model is better at some tasks than state-of-the-art models from OpenAI, Anthropic, Google, and xAI. “The Muse Spark is the first step on our upward ladder,” Mita said in a statement Blog postIn reference to its goal of building artificial intelligence that far exceeds human capabilities.
Artificial Analysis, an AI measurement company that has received early access to Muse Spark, He said On social media, the new model is one of the best models tested. “The Muse Spark scored 52 on the AI Analysis Index, which places it in the top 5 models we measured,” the company said in its post, citing its own evaluation model for scoring models that combine different third-party benchmarks.
Meta says the new model is multimodal in nature, meaning it has been trained to handle images, audio and video in addition to text. Muse Spark also features advanced reasoning capabilities, a key feature of the best AI models available today, and was designed from the ground up with powerful coding capabilities. Meta described these features as the foundation for building more capable models using modern machine learning methods.
Meta says it built Muse Spark to be particularly good at providing medical advice. “To improve Muse Spark’s health reasoning capabilities, we collaborated with more than 1,000 doctors to curate training data that enables more realistic and comprehensive responses,” the company said in its blog.
Zuckerberg has spent a small fortune to overhaul Meta’s AI efforts since Llama 4 came out. The tech giant has poached top AI engineers from rival companies with compensation packages worth its salt Hundreds of millions. It has also spent billions to acquire or make major investments in a number of startups in the field of artificial intelligence. Meta has hired Alexandr Wang, CEO of Scale, an AI training company, to lead its AI efforts after investing $14.3 billion in the company.
Meta also published a document outlining its vision for safely scaling AI models to superhuman performance levels. Company An advanced AI measurement framework It outlines the safety checks the company will perform as its models become increasingly advanced.
