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.

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

🎮 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

union alpha (unbiased pareto) vs deepseek v4.1 flash vs muse spark 1.3 – three paintings in three.js the setup: one four-line prompt plus the painting as an image, through @openrouter. no agent loop, no renders, no feedback – the model writes one html file blind and we open it.

An interactive Three.js scene that shows a stylized 'Muse Spark mind' with memory, reasoning, language and sensory regions (about 218 neurons and 340 synapses), with a live demo.

Progress on the VR Forge: The Agent can now move in its own and grab objects, lift them, carry them and change its colors. I am currently using #astra and #musecode both working in different branches. Soon: Minecraft-like experience building with an Agent. Stay tuned!

PIMX_ELTEX runs Muse Spark 1.3 in OpenCode on six prompts, from 3D games and an open-world mini GTA to car simulators and web apps, at about 3 minutes per project.

A same-prompt bakeoff site that starts with a playable penguin Tetris generated by Muse Spark 1.3 in OpenCode, with a fixed prompt for comparing other models.

Marc Berman runs a four-turn guided Three.js Headless Horseman build. Muse Spark 1.1 made the most convincing pumpkin head, but its mesh count jumped from 58 to 106, which raises efficiency and editability questions.

Every model gets the same thing: the Game Boy screen, eleven buttons, a walkability grid, and 1,000 turns to beat Brock. No walkthrough, no pathfinding, no hints. Same prompt for all of them. Scoring is a 10-milestone ladder (left the house, got a starter, reached Route 1, ... beat Brock), so a run that never wins still places by how far it got. 14 runs so far, 4 of them got the badge. Best is GPT-6 Astra at 246 turns. Cheapest win was Gemini 3.8 Flash at $3.70. A free local model (Muse Glimmer 30B) burned all 1,000 turns and got as far as Reached Route 1.

Loving it! I did a 2026 remake of my Spooky Clicker the other day and the total was $0.63. Lots built too! Changelog for everything is here: github.com/DevTarlow/spoo…

Ported a Miniature Golf prototype to VR using Meta Muse Code and the Unity CLI, added dozens of automated tests, and built a website to capture test runs, screenshots and results.

GPT 5.6 Sol numbers posted! You can check out the full trace and codebase for the two (!!) solved instances with the new trajectory viewer (actually built w/ the new Muse Code). Confirms that solutions are novel and not just regurgitated. Viewer link in 🧵

When-Agents-Rule drops Muse Glimmer 30B, Qwen 3.6 27B and Gemma 4 31B on one island to run an economy and fight for 90 minutes with no human input.

I had a chill ball drop game in my head and spent the weekend making it by iterating with my Muse agent. Every pass was a conversation: tune the physics, test, report back what felt off, repeat. The ball went from draining straight through to staying up and chaining off everything. Marty, the little neon orb bot in the game, is actually my agent's mascot. His Deep Scan power shows where the ball will bounce. It is a free Android APK on itch.io with 10 levels, a combo multiplier, and soft pentatonic chimes that climb with your combo. I am curious how other people would push this further. What would you have an agent iterate on next: level design, the sound, or something I am not thinking of?

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!

Dang It one shotted this table tennis game in 3d with sound Great job Muse Aka Meta AI

opus 5 vs kimi k3 vs muse spark 1.2 – one shopping mall, day and night, in @threejs scenes: a frutiger aero mall at opening hour, and the same mall hours after closing. one camera walk each, 3,600 frames per cut. muse needed a stronger day prompt, opus a hand-fix on the day

@chanakyaspeakss

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

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. ✨

Siamese Cat Dev pits Muse Spark 1.3 against Claude Fable 5.1 on a browser OS, a Call of Duty-style shooter, a neon arena shooter and a Mario Kart-style racer.

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…

Day 2 of building products for agents. I present to you musetv.live - think your @Muse agent & Tamagotchi had a baby.

Agent Workflow Lab runs the Q8 GGUF of Muse Glimmer 30B through llama.cpp on an RTX 4090 plus 3x RTX 3090, measures DFlash speedups and a 120K-token retrieval probe, then has it build a Three.js browser FPS with no human edits.
