Muse Spark 1.3 is here🙌 — and 3D game dev is getting seriously fun. I’ve been having so much fun building alongside Muse Code — turning ideas into playable 3D worlds and iterating together along the way. A glimpse of what’s possible ↓ research.meta.ai/artifacts/intr…

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

Excited to share Muse Spark! It's a strong natively multimodal model with many surprising properties that emerged. Here, the model is able to use Python tools to make a playable Sudoku game on the web from an image input of the board. ✨

Decided to stress test Muse Spark 1.3 xhigh on 3D game logic in Three.js. Built out an entire browser driving demo with different daytimes, and vehicle physics. TBH the result is so much better for the time I spent on it. @threejs @alexandr_wang Try: gg-shifro.vercel.app

Bijan Bowen runs Muse Spark 1.3 through a browser OS, C++ skate game, subway FPS, 3D CAD Hot Wheels, a Blender/Godot wrestling game and more, then tallies the total cost.

Muse Glimmer one-shot 5 games! @AIatMeta dropped Muse Glimmer. So we ran it against Muse Spark 1.2, on five one-file game demos, each one written to play itself: Tetris, a top-down pixel street race, a rooftop web-slinger, a blue hedgehog platformer, and Flappy Bird. the setup:

Muse Spark 1.3 Max is out and I already love how good it is at 3D stuff. We’re so back.

Fun visually-grounded 3d visualization with Muse Spark - by asking the model to generate a 3d visualization of how much each component cost on a xbox 360 motherboard (and put the bar on the component).

muse spark 1.3 is really good with 3D and three.js it recreated Lies of P's mechanical heart from multiple screenshot references it generated an exploded view too. so cool!

Hello everyone! 👋🕶️ I put Meta Muse Code + the Unity CLI to the test with a real Unity project to see how far I could push this agentic workflow. Instead of just generating code, I wanted to see how it could actually interact with Unity, run tests, validate changes, port the h

I wanted to try something quick with Muse Spark 1.3, so I had it build this pirate platformer. It was incredibly fast and worked flawlessly at one-shot! Now I’m enhancing the artwork, sprites and adding new levels 😊This is such a fun coding model, it just works, fast and cheap!

🎮 This entire Avo Lawn game was built with Muse Spark 1.2 + Muse Code. 🥑 Now it’s your turn—use Muse Spark 1.2 to build your own game and see what you can create. To play: research.meta.ai/artifacts/intr… Check out our blog post: research.meta.ai/blog/introduci… h

No place like localhost has Muse Glimmer implement a 7-stage development plan for a classic arcade game clone, the same challenge earlier run against three Qwen models.

Muse Spark 1.3 released today, so I immediately tried it in Muse Code with the Miniature Golf game I previously converted to VR using version 1.2! 💻 The prompt “Add Hands support & allow for hands or controllers. Use MetaVR CLI for additional ISDK context” The entire process

Ok, here’s the VR port of my Miniature Golf prototype! ⛳🥽 This project is now running on standalone (macOS/Linux/Windows), Three.js, and as of today, VR. Crazy how fast we can move today. The VR version was fully ported using Meta Muse Code and the Unity CLI. I also now have

I had one shotted this with explicit instructions to create this game with all the Asset specifications on @opencode and it generated in 30-40 Seconds. Couple more iterations and inputs will give us a production ready game. Great Job Team Meta #ReverseSonic

Meta for Developers

@MetaforDevs

Muse Spark 1.3 with max reasoning is now available on Muse Code and Meta Model API. Developers can build with frontier performance without the frontier prices. We thought showing would be better than telling, and encouraged our friends in Meta Superintelligence Labs to come up

Try planning with Muse Spark 1.3 Max and then executing with Muse Spark 1.3 xHigh Contributor agents, It cuts costs by more than 90% while still giving you frontier model quality. Honestly, Muse Spark 1.3 Max is one of the best models on the market right now. Everything you see

Backgammon is one of the oldest known board games, combining strategy and luck. It is a two-player game where each player has 15 pieces, often called checkers or stones, that move along 24 triangular spaces called points according to the roll of two dice.

Dilmer Valecillos uses Muse Code with Muse Spark 1.2 and the Unity CLI to run tests, validate changes, port a Mini Golf game to other platforms and convert it to VR.

Bijan Bowen puts Muse Glimmer through a battery of builds including a browser OS, C++ skate game, subway FPS, 3D CAD model, drum-kit sim and multimodal coding.

Meta's open-sourced Muse Glimmer 30B vs Muse Spark 1.2 Glimmer delivered 5 runnable games at roughly one-fifth Muse Spark's cost. Very Interesting experiment by @aimlapi . the setup: • Muse Glimmer 30B — via aimlapi[.]com. cost: $0.02 • Muse Spark 1.2 — via aimlapi[.]com.

I tested DeepSeek V4 Flash, Kimi K3, and Muse Spark 1.3 on the same Flappy Bird prompt. @Meta Muse Spark 1.3 was my favorite. It built the most complete game with a polished UI, animated bird, layered parallax, pipes, scoring, persistent best score, and a proper game-over
