At our Meta Connect 2026 AI glasses hackathon, developers had 90 minutes to build with Muse Code. By the end, they were demoing new web apps for Meta Ray-Ban Display.

Congrats to @JoyReignVr, who took home the top prize with Pocket Quest, an experience that turns everyday surroundings into bite-sized adventures. 🏆

Open weights, meet your favorite stack.

We're teaming up with @FireworksAI_HQ, @baseten and @modal for the Meta Global AI Developer Hackathon, so you can run Muse Glimmer and Muse Spark Open on the tools you already build with.

Compete for a share of $1M in prizes. Applications close Oct 25.

"It's a human who has to put on the headset and see if your interaction is natural or not."

That's @AshrayPai answering a question about agentic tools from Meta developer advocate @Dilmerv in episode 1 of Unscripted, our new series where a developer and a Meta developer advocate candidly take turns answering questions about building on Meta platforms.

In this episode, Ashray and Dilmer shared how they use agentic tools to accelerate VR development. Scaffolding, SDK and package setup, debugging and test runs all go to Ashray's agents. Comfort and interaction quality stay with him, in the headset. He sums it up as anything that needs testing can go to an agent, and anything that requires judging needs a human.

Watch episode 1 to hear how both of them use agentic tools in their day-to-day workflows and stay tuned for more episodes 👉 https://t.co/DSfIQ445uy

[Meta for Developers @MetaforDevs]

Muse Wonder is now available on @Cline, @Cloudflare, @Cognition, @Cursor_AI, @OpenRouter, @Oracle and @Vercel - with more partners coming soon.

We look forward to seeing what the community builds with Muse Wonder!

Start building 👉 https://t.co/QJT3aIZNd1

[Meta for Developers @MetaforDevs]

Muse Wonder is available today on Meta Model API and in Muse Code, and Muse Wonder Full is launching exclusively for Muse Code subscribers.

The Muse Wonder series combines frontier coding, long-running agents and advanced computer use capabilities to tackle developers’ most demanding work. (1/3)

[SGLang @sgl_project]

Muse Spark Open is built to plan, act, and use computer across agentic tasks for life and work.

You can now build a powerful personal AI agent with an open stack, and SGLang to make it:

- Ultra-responsive with NVFP4 MegaMoE and sequence parallelism
- Faster for agentic and coding tasks with our DFlash2 draft model
- Customizable for specialized use cases via fine-tuning with Miles

We’re incredibly proud to have made this possible with @AIatMeta, @NVIDIAAI, @AIatAMD, @intel, and @radixark!

[Meta for Developers @MetaforDevs]

Today, we’re releasing the weights for Muse Spark Open, giving developers more control over how they run, customize and deploy the model. (1/5)

[Alexandr Wang @alexandr_wang]

muse spark open.

why 2026 won't be like 1984 

[Meta for Developers @MetaforDevs]

We’re excited to get Muse Spark Open into the hands of the developer community and can’t wait to see what you build with it.

Today, we’re releasing the weights for Muse Spark Open, giving developers more control over how they run, customize and deploy the model. (1/5)

[Meta for Developers @MetaforDevs]

It runs on leading inference engines like SGLang, vLLM, TensorRT-LLM, Hugging Face Transformers, Apple MLX, llama.cpp, and Unsloth with optimizations for AMD, Apple, Intel, and NVIDIA silicon. Developers can easily further customize the model using the PyTorch framework. (4/5)

[Mark Zuckerberg @finkd]

Muse Spark Open -- weights releasing today -- runs great on new Mac Studios thanks to work with @johnternus and Apple.

[Meta for Developers @MetaforDevs]

New in Immersive Web SDK 1.0: your coding agent can now run and test your app itself, either in the desktop emulator or on a Meta Quest connected to your computer. It finds the slowdowns your users would hit before they do.

Start building with IWSDK 👉 https://t.co/aHfS0UJeAl

[Meta for Developers @MetaforDevs]

Before you adapt your game for hands, decide whether it's a fit. Speed plus precision, thumbstick-style control, and simultaneous actions all raise the cost of the port.

This lesson and others are now available for developers on Meta VR Academy 👉 https://t.co/neVcOw27rP

[Andrew Brown @andrewbrown]

Meta adding a frontier model paired with filling out their API catalogue tells me the are going to be a first-tier AI provider.

I think people have been sleeping on Meta.

[Andrew Brown @andrewbrown]

Meta's gone full-tilt, and I'm glad to see another competitor with a full AI catalog of services.

I've been running a heavy amount of AI experiments using Meta, and its was already passing my "good enough", and a fraction of the price.

I'll have give Muse Wonder a go with some single shots today.

MUSE WONDER 🍉

muse wonder is the best model in the world for personal agents and professional agents.

we evaluated our model against the best models in the world across agentic and coding tasks, and we think you all will like it.
