VibeWorlder Models

VibeWorlder is the open model family trained for vibe worlding: Embedding-4B, 8B and the 30B-A3B mixture-of-experts agent.

VibeWorlder is not a consumer app. It is a set of open weights that act inside VibeWorlding-Gym. The 16 August 2026 release lists VibeWorlder-Embedding-4B, VibeWorlder-8B and VibeWorlder-30B-A3B.

Early public notes claimed the 30B mixture-of-experts agent can beat closed general models on this specific 3D construction bench. That is a benchmark result, not a claim that the model replaces a game engine. Read the paper tables before you quote a ranking.

For product work, treat VibeWorlder as a research agent you can fine tune or evaluate. For a playable browser world this week, write a blueprint and send it to OpenGame.
