Muse Spark 1.3 is now available in Box AI. What our evaluation of Muse Spark 1.3 found: → 13% accuracy lead over comparably priced models on the Box Complex Work Eval → 42% faster than Muse Spark 1.2 using roughly a third fewer tokens → Strongest gains in Financial Services, Technology, and Energy

Come and build the future of superintelligence at the Meta Global AI Developer Hackathon. Ten days, access to our newest models and $1M in prizes. It’s virtual, worldwide and free to enter. Be the first to know when applications open →

We’re excited to partner with Meta to deliver day-one support for Meta VR Glasses 🤝 Add hands support to your Quest title or build something new. With Unity, it's one codebase that can be used across multiple devices, enabling developers to reach more VR players on more platforms with less friction. Download or upgrade to Unity 6.6 or higher to start creating today. @MetaHorizonDevs

We're helping devs move faster with greater choice over what they build, where they deploy, and how they scale. Excited to bring @AIatMeta frontier agentic and coding intelligence to the community with Muse Spark 1.3 on @Oracle and @googlecloud 🚀

Muse Spark 1.3 from Meta Superintelligence Labs, the latest frontier model, is now on Gemini Enterprise. Learn how to deploy Muse Spark 1.3 from Meta on Google Cloud’s secure infrastructure today →

That's it from the developer state of the union! Everything we shared has a dedicated developer session with more details on where to get started and key considerations you should know. Explore deep dives into our AI models, AI glasses and Horizon 👉

Muse Spark 1.3 is now available through @Oracle, with availability on @GoogleCloud in private preview. We’re excited to give developers more choice in where they build and deploy by expanding access to our frontier coding and agentic model through our preferred cloud platform partners.

We believe the future is for everyone, so we're putting superintelligence in everyone's hands. The Developer State of the Union is live: what's shipping, what's in preview, and what's changing across our SDKs, APIs, and tooling. This is the surface you'll build on. Plus where to start today.🛠️ #MetaConnect# During the livestream, you can experience the virtual content in a number of languages on

Muse Code is now an import away. muse-code-sdk is an asyncio-first Python client for Muse Code sessions: spawn or attach, stream a turn, handle tool approvals, resume later. pip install muse-code-sdk

To help more developers build with Muse Spark 1.3 at our contributor tier pricing, we're rolling out optimizations. In our testing, it has a 1-2% variance on our aggregate benchmarks compared to the standard tier. We've been using it for a while and noticed no differences in capability in our own usage. The reception for Muse Spark 1.3 has been great - keep building and share feedback! We're eager to keep improving performance and capability.

Meta’s Segment Anything Model (SAM) 3.1 is now available on Meta Model API, giving developers a fast and lightweight model for detection, segmentation and tracking in a single call on inference tuned for SAM 3.1's architecture. Use a short phrase to find objects in images and video. One API call returns detections, pixel-precise segmentation masks, and identity-preserving video tracks. Learn more and start building:

One of the biggest requests has been Muse Code for Windows Today, we're excited to share that Muse Code is now native on Windows (no more WSL!) 🎉 Try it: irm | iex

Last night, I built a VR game prototype in a few hours with Muse Code on PC. It was already available on macOS and Linux, and today we’re bringing it to PC! 🔥 I tested it with Unity through the Unity CLI, and here are a few things that worked really well for me: - Having Muse Code on PC alongside Link, which is only supported on Windows, makes testing in the headset so much faster. - I built one feature at a time, just like I do with other agents: a Unity project ready for MR/VR, then the core mechanic, the game loop, and finally the environment. - I added rules to AGENTS md to prioritize Meta VR CLI for context. This worked really well for implementing the hand tracking punch mechanic and power up. - After initially testing in Meta XR Simulator, I found that the shaders needed changes for stereo rendering in VR. Muse Code handled those updates really well. 𝗧𝗼 𝗶𝗻𝘀𝘁𝗮𝗹𝗹 𝗶𝘁, run these commands: irm | iex Give it a try with a VR idea you’ve been wanting to prototype, or a feature in your existing game. Create a branch and give yourself room to experiment! What’s the one VR/MR feature you’d want me to try building next? 👀

Muse Code from Meta is now available natively on Windows - no WSL required. It’s PowerShell-fluent, sandboxed by default, native x64 and ARM64, and supports zero-admin install. Coming soon: intersession messaging. Get started: irm | iex Learn more:
