Projects to explore
- impeccable Stop your AI coding agent from making every site look the same
Impeccable is a design skill for AI coding agents that pushes back against the handful of visual habits (the same font, the same gradient, cards nested in cards) that show up on nearly every AI-generated interface.
- Superpowers Make your coding agent agree a plan before it writes code
Describe what you want to build and have your AI coding agent ask questions, agree a written design with you, and only then write code from a step-by-step plan with tests.
- build-your-own-x Rebuild Git, Docker or a database from scratch, step by step
A curated index of step-by-step guides for recreating the technologies you use every day.
- project-nomad Run offline Wikipedia, books, and AI chat with no internet
Project NOMAD turns a small computer into a self-contained library and AI assistant that works with no internet connection: offline Wikipedia and reference books, Khan Academy-style courses with progress tracking, downloadable regional maps, and a local AI chatbot you can hand your own documents to.
- Multica Put AI coding agents on the same kanban board as your team
Multica is a project-management workspace where AI coding agents get assigned issues the same way a human teammate would: they pick up the work, comment on progress, raise blockers, and hand it back for review, all visible on the same board as your human team.
- json-render Let an AI model design app screens, safely, from a fixed parts list
json-render is a programming toolkit (framework) for "generative UI": instead of letting a model write arbitrary code for a screen, you give it a fixed catalog of components it is allowed to use, and it returns structured JSON describing which ones to show and how, which the framework then renders.
- Qwen3.8-27B Run a 27B model that reads images and video yourself
Run a 27-billion-parameter model that reads text, images and video and writes text back, on hardware you control.
- starnet Watch your AI agents work inside a living pixel-art space station

- jev-ultrafast Watch an AI agent search Google Flights in about 7 seconds
Jev Ultrafast is a browser-automation agent that completes a task like searching flights by reading the page, then asking Jev which button, field, or link to act on next — a decision that takes milliseconds instead of the seconds a normal chatbot needs to 'think' about it.
- NanoJev Watch a tiny open model out-play Jev at Doom, maze, and Snake
NanoJev is a small (0.6-billion-parameter) open reproduction of Jev: a model that reads a game or task state and a set of possible actions and returns a full probability distribution over them in one pass, with no text generation.
- minecraft-agent Watch AI agents beat Minecraft's Ender Dragon in under 9 minutes
This project pairs two AI systems to play Minecraft: a planning model (the creator's own 'Astra') decides the overall strategy, while Jev picks the moment-to-moment actions — movement, camera angle, item use — needed to carry it out, sent through the normal player controls rather than by editing the game's code.
- TRELLIS.2 Turn a single photo into a downloadable 3D model
TRELLIS.2 is Microsoft's image-to-3D model: give it one picture of an object and it generates a full 3D asset — a mesh with physically based rendering materials, including transparent or translucent parts — using a 4-billion-parameter model and a new “O-Voxel” representation designed to handle shapes that older methods struggle with, such as open surfaces and thin structures.
- yue2-hum-to-song Hum a tune for 30 seconds and get back a finished song
Hum to Song takes a hummed melody (10 to 30 seconds), plus a style line and lyrics you provide, and turns it into a produced song that keeps your original tune and builds a full structure around it.

Control already-trained reinforcement-learning policies for Pollen Robotics' Microduck robot entirely client-side: physics run through MuJoCo compiled to WebAssembly and the policy network runs via onnxruntime-web, with no server involved.
- nemotron-diarization See who's speaking and when, live from your microphone
Live Speaker Diarization is Nvidia's browser demo for figuring out “who spoke when” in audio: start your microphone or upload a short recording, and it labels overlapping speaker turns in near-real time, showing speaker-activity lanes alongside a live transcript.
- open-jev Watch a Jev-style model answer instantly next to a normal chatbot
This Space runs System One, an independent reproduction of TypeSafe's Jev idea: Qwen3.5-4B-Base fine-tuned with a small scoring head so it answers a typed question with a calibrated probability across exactly the options you supply, instead of writing a free-text answer.
- gods-eye-view Watch live planes, ships and satellites on a 3D globe
gods-eye-view opens a photorealistic 3D globe in your browser and plots public live feeds on it: aircraft transponders, ship beacons, satellite orbits, earthquakes, and public traffic and security cameras.
- VoiceStudio Clone your voice and dub a video, all on your own computer
VoiceStudio is a desktop app for generating speech in a chosen voice without sending anything to a company: give it a clean reference recording, type your text, and it generates the audio, with separate workspaces for dubbing video and for designing a brand-new voice from a written description instead of a sample.
- supervision Add boxes, tracking and zone counts on top of any vision model
Supervision is a Python library of the parts that sit around a computer vision model rather than inside it: loading datasets, drawing boxes and masks, tracking an object across frames, counting what crosses a zone, and measuring how well a model did.
- YuE Generate a song, then edit its melody and chords before rendering
YuE2 is a music generation system that writes a song in two visible steps: given lyrics and a style description, it first produces a melody-and-chord plan in ordinary notation, then turns that plan into finished audio with vocals and backing.
- open-source-games Find open-source games and open remakes of classics to play
