Not sure what model Space Bunny is, but I am impressed.

I had a chance to test it this week.

It's free in OpenCode for the next week, with a 1M token context window and image input.

I focused my tests on visual work, mostly starting from a single image or sketch.

Here are my results.

Overall, its visual understanding is excellent, and its design taste is strong. One behavior that stood out is that it checks its own work. When it has a browser, it opens the page, looks at screenshots, and fixes what it sees before it says it's done. These verification capabilities matter in long-horizon agents.

From a rough wireframe with seven handwritten notes, it built a full landing page and followed every note.

From one photo of a moka pot, it built a 3D model that matches the original down to the eight-sided body, the brass valve, and the camping stove underneath.

It built a 3D anatomy of a mirrorless camera with 67 labeled parts, an 11-element lens, a 9-blade iris, and an exploded view. Very excited about these results.

I asked it for a 60-second animated proof of why a circle's area is πr². It built the whole thing, with slices that rearrange into a rectangle, a live slider, captions, and narration. Not perfect, but still impressive.

I gave it a rough hand-drawn sketch of a game level. It built a playable 3D game in Three.js that follows the sketch and all ten rules I wrote on it. Then it playtested its own jumps in Chrome and tuned the physics until every lava stone was reachable.

Based on this, I would reach for it for image-to-code work, interactive prototypes, and creative coding in 3D.

It’s also quite fast, which makes it great for rapid prototyping.

Space Bunny generated everything in the video in OpenCode. I wrote the prompts and supplied the images.
