Introducing Muse Spark: MSL’s First Model, Purpose-Built to Prioritize People

Update on May 12, 2026 at 7:00AM PT:

When we launched Muse Spark last month, we said we'd bring it everywhere. Today, we are - with faster voice responses in the Meta AI app, smarter AI glasses, and new ways to shop and get help in your conversations. Thanks to Muse Spark, Meta AI is now more capable, more contextual, and more useful in your everyday life.

Voice Conversations

In the Meta AI app, Muse Spark lets you talk naturally with the assistant - interrupt, switch topics, or swap languages. As you talk, Meta AI can generate images and pull up recommendations from Reels, maps, and more.

We're also bringing live AI to the app (a feature already available on our AI glasses), so you can point your camera at the world and ask about what you're seeing in real time, whether that's a landmark you're passing or something you need help with around the house.

New Shopping Features

You can now ask Meta AI in shopping mode to search Facebook Marketplace listings near you alongside options from across the internet - bringing used and new items together in one place, with a map to see where each one is. From there, refine by price, style, or distance. You can also @ a specific brand or creator to browse their public content directly and scroll through products in a new grid format.

Powering Intelligence Across Our Glasses and Apps

Muse Spark is starting to gradually roll out on Ray-Ban Meta and Oakley Meta glasses in the US and Canada over the next few weeks, and on Meta Ray-Ban Display this summer. Beyond the app and glasses, Muse Spark is starting to bring the same intelligence to Meta AI across WhatsApp, Instagram, Facebook, Messenger, and Threads - in places like search bars, group chats, posts, and more. We're testing a couple new experiences here too: side chats that let you tap the Meta AI icon from any group chat to get a quick, private answer grounded in what your group is discussing, and @meta.ai mentions in Threads posts and replies.

Muse Spark and the new Meta AI are reaching billions of people across our apps - meeting you where you are, faster and more helpful than ever.

Today we are announcing Muse Spark, the first in a new series of large language models built by Meta Superintelligence Labs. We are on our way to personal superintelligence: an assistant that can help anyone, anywhere with the things that matter most to them.

A New Model: Muse Spark

Over the last nine months, Meta Superintelligence Labs rebuilt our AI stack from the ground up, moving faster than any development cycle we have run before. Muse Spark is the first model in our new Muse series - a deliberate and scientific approach to model scaling where each generation validates and builds on the last before we go bigger. This initial model is small and fast by design, yet capable enough to reason through complex questions in science, math, and health. It is a powerful foundation, and the next generation is already in development. Muse Spark now powers the Meta AI assistant in the Meta AI app and meta.ai, built to support complex reasoning and multimodal tasks.

What's Changed With Meta AI

The Meta AI app and meta.ai are getting an upgrade today, along with a new look. Whether you need a quick answer or help with complex problems that need strong reasoning, Meta AI now handles both. You can switch between modes depending on the task, and Meta AI can launch multiple subagents in parallel to tackle your question. Like planning a family trip to Florida where one agent drafts the itinerary, another compares Orlando vs. the Keys, and a third finds kid-friendly activities - all at the same time, giving you a better answer, faster.

Ask Meta AI: It Understands

The real world moves fast, and most of it does not fit into a text box. That is why we built strong multimodal perception into Muse Spark, so Meta AI can see and understand what you are looking at, not just read what you type. Snap a photo of an airport snack shelf and Meta AI can identify and rank the snacks with the most protein - no label-squinting required. Scan a product and ask how it compares to alternatives. It is the difference between an AI that waits for you to explain the world and one that can simply look at the world with you. And when Meta AI powered by Muse Spark comes to our AI glasses, the assistant will be able to better see and understand the world around you.

Multimodal perception is especially valuable for health. With Muse Spark, Meta AI is now able to help you navigate health questions with more detailed responses, including some questions involving images and charts. Health is one of the top reasons people turn to AI, so we worked with a team of physicians to develop the model's ability to provide helpful information on common health questions and concerns.

Muse Spark excels at visual coding, letting you create custom websites and mini-games straight from a prompt. Ask Meta AI to build a dashboard for planning a big surprise party, spin up a retro arcade game to chase a high score, or launch a whimsical flight simulator - and share any of them with friends.

Ask Meta AI: It's Plugged Into What You Care About

Meta AI can now help you discover what to wear, how to style a room, or what to buy for someone you know. Shopping mode draws from the styling inspiration and brand storytelling already happening across our apps, surfacing ideas from the creators and communities people already follow.

And when you are looking up a place to go or a topic that is trending, Meta AI surfaces rich and relevant context right alongside the conversation. Tap into a location and see public posts from locals who know the area. Ask what people are buzzing about and get the full picture, pulled from content and community posts. It is context from your people, right where you need it.

Looking Ahead

The Meta AI app and meta.ai will have the upgraded experience with Instant and Thinking modes everywhere they are available today. The new Meta AI features are starting to roll out in the US on both. In the coming weeks, we will bring these new modes and capabilities to more countries and to the places where people use Meta AI, including Instagram, Facebook, Messenger, WhatsApp, and our AI glasses - where these perception capabilities become even more powerful. We are also opening access to the underlying technology. It will be available in private preview via API to select partners, and we hope to open-source future versions of the model.

This is only the start. As we expand these features, expect richer, more visual results, with Reels, photos, and posts woven directly into your answers, with credit back to the content creators. And as our models improve, we'll continue to build safeguards for things like safety and privacy, starting with the strengthened risk framework and other protections we're sharing today.

The future of Meta AI is rooted in the relationships and context already at the center of your life. We are building toward personal superintelligence - an AI that does not just answer your questions but truly understands your world because it is built on it.
