Meta Unveils ‘Muse Spark’ AI Model Built in 9 Months, Aims to Power Instagram, WhatsApp and Facebook

Meta says that Muse Spark can compete with models like Anthropic's Cloud Opus 4.6 and OpenAI's GPT 5.4 on some benchmarks. These benchmarks include multimodal reasoning, health applications, and agentic AI.

Alexandr Wang explained that Muse Spark's contemplating mode can manage multiple agents working in parallel to handle complex tasks. He added, "In our tests, we found it capable of competing with other highly advanced reasoning models like Gemini Deep Think and GPT Pro."

Wang explained that Muse Spark can understand the world around you. This AI can solve complex problems in science or math, and even provide insights into your conversations on Meta's apps. He claimed that this AI is "built for the 3 billion people who already use Meta apps every day."

Muse Spark will power an updated version of Meta AI, available on the Meta AI app and website. It is set to expand to Facebook, Instagram, WhatsApp, Messenger, and Meta's smartglasses. It also features a new shopping mode that offers suggestions tailored to creators and brands.

With Llama models, Meta's strategy was to keep them open source. That is, the code for the models was available to the public. However, Muse Spark is closed source. However, the company says it hopes to open-source future versions of the model.

Currently, Muse Spark is available as a private API preview for select partners. Alexandr added that this was just the first step. He explained, "Even larger models are already in the works, and the infrastructure is being expanded accordingly."
