geebr.world brings dumb NPCs to life with Gemma 4 E2B
Autonomous characters that walk, talk, and set fires—all on a 6-year-old laptop.
Developer runvnc built geebr.world, a browser experiment where tiny AI models power intentionally dumb NPCs on a six- or seven-year-old HP Omen with an RTX 2060. The small model makes characters "dumb," so the project leans into silly behavior like walking, talking, pushing barrels, and casting fireballs on an ASCII map. Users can save an animated PNG via the Record feature that preserves the initial state and agent instructions when dragged back into World Setup. Check out the live demo at geebr.world or the MIT-licensed code on GitHub: https://github.com/runvnc/geebr.world.
- Uses Google's Gemma 4 E2B model running entirely in the browser on a 6-year-old HP Omen with RTX 2060.
- NPCs can walk, talk, push barrels, and cast fireballs that modify the ASCII environment.
- Record feature saves state as an animated PNG that can be shared and re-loaded by others.
Why It Matters
Proves small local AI models can power playful, interactive NPCs, unlocking creative low-spec browser games.
