Llama is no more; Muse Spark is here. Meta has relaunched its artificial intelligence efforts with a new model named Muse Spark.

Unlike the announcement of Anthropic’s Claude Mythos Preview, Muse Spark is available to the public today.

Meta is preparing to compete with high-end Gemini and ChatGPT models with its new Thinking mode, which it states will be rolled out gradually.

Muse Spark replaces Llama models

Last year, Meta restructured its AI efforts by forming a new team called Meta Super Intelligence Labs, led by Alexandr Wang. Today, as it introduces Muse Spark, Meta refers to this model as "the first step on our scaling ladder."

“Muse Spark offers competitive performance in multimodal perception, reasoning, health, and agency tasks,” says Meta. “We continue to invest in areas with existing performance gaps, such as long-term agency systems and coding workflows.”

As part of the announcement, Meta demonstrates how Muse Spark Thinking provides advantages compared to Anthropic’s Claude Opus 4.6 Max, Google’s Gemini 3.1 Pro High, OpenAI’s GPT-5.4 Xhigh, and xAI’s Grok 4.2 Reasoning models.

Muse Spark is now available in Meta AI applications as of today.

Thinking mode is coming

Muse Spark Thinking is just a mode. Muse Spark Thinking mode will compete with Gemini 3.1 Deep Think and GPT-5.4 Pro.

We also offer a Thinking mode that orchestrates multiple agents reasoning in parallel. This allows Muse Spark to compete with advanced models like Gemini Deep Think and GPT Pro in their extreme reasoning modes. The Thinking mode provides significant capability improvements in challenging tasks, achieving 58% success in Humanity's Final Exam and 38% in Border Science Research.

Meta also notes that it has opened a special API preview for select partners.

Health is a specialty area for Spark

What is Muse Spark best suited for? Meta highlights its multimodal expertise in “visual STEM questions, entity recognition, and localization.”

Meanwhile, health is another strong area for Muse Spark, according to Meta:

One of the greatest applications of personal super intelligence is to help people learn about and improve their health. To enhance Muse Spark’s health reasoning capabilities, we have collaborated with over 1,000 doctors to prepare training data that provides more realistic and comprehensive responses. Muse Spark can create interactive visuals that reveal and explain health information, such as the nutritional content of various foods or the muscles activated during exercise.

In the meantime, we will see the results of Apple’s new agreement with Google in less than two months at WWDC 2026. iOS 27, featuring Gemini-powered Siri and Apple Intelligence capabilities, will be introduced on June 8.
