Finish line on Wednesday announced its first major model since CEO Mark Zuckerberg relaunched the company’s artificial intelligence efforts last year under a recent division called Meta Intelligence Labs. The model, called Muse Spark, is a step toward Zuckerberg’s vision of “personal superintelligence,” the company says, and will remain closed source for now.
– Zuckerberg announced on social media post that Meta’s goal is to create AI products that “not only answer your questions, but act as agents that do everything for you.” The billionaire added that he is “optimistic that this will support a wave of creativity, entrepreneurship, growth and health.”
Muse Spark certainly appears to be a major improvement over the last major Meta release, Llama 4, which was released in April 2025 and was seen as a disappointment in the tech industry due to its mediocre performance.
Meta makes Muse Spark available through meta.ai and the Meta AI app. Unlike Lamy, Muse Spark is not available for third-party downloads, although the company says it hopes to open-source future versions. Meta was previously seen as a leader in open-source artificial intelligence and has made its llama models available for researchers, startups and hobbyists to download and customize.
“As we look to the future, we plan to release increasingly advanced models that push the boundaries of intelligence and capability, including new open source models,” Zuckerberg wrote.
Meta’s reported benchmark results for Muse Spark suggest that the model performs better on some tasks than the latest OpenAI, Anthropic, Google and xAI models. “Muse Spark is the first step on our scaling ladder,” said Meta in: blog postreferring to the goal of building artificial intelligence that significantly exceeds human capabilities.
Artificial Analysis, an artificial intelligence benchmarking company that gained early access to Muse Spark, he said on social media that the recent model is one of the best he has tested. “Muse Spark scores 52 on the Artificial Intelligence Index, putting it in the top five models we tested,” the company said in its post, citing its own scoring model rubric that combines various third-party benchmarks.
Meta claims that the recent model is natively multimodal, meaning it is trained to handle images, audio and video, as well as text. Muse Spark also offers advanced inference capabilities, a key feature of the best AI models available today, and was built from the ground up to provide powerful coding capabilities. Meta has identified these features as the basis for building increasingly proficient models using current machine learning methods.
Meta says it designed Muse Spark to be especially good at providing medical advice. “To enhance Muse Spark’s health reasoning capabilities, we have worked with over 1,000 physicians to develop training data that enables more evidence-based and comprehensive responses,” the company said in its blog post.
Zuckerberg has spent a compact fortune modernizing Meta’s AI efforts since the launch of Llama 4. The tech giant has been stealing top AI engineers from rival companies with compensation packages worth hundreds of millions. It has also spent billions acquiring or making significant investments in a number of artificial intelligence startups. After investing $14.3 billion in the company, Meta hired Alexander Wang, CEO of Scale, an artificial intelligence training company, to lead its artificial intelligence efforts.
Meta also published a document outlining its vision for safely scaling AI models to superhuman levels of performance. Business Advanced AI scaling framework outlines the security checks the company will perform as its models become more advanced.
