Fable 5.1 made a Minecraft mod for $20

Anthropic just dropped Fable 5.1, so I decided to build a Minecraft mod with it. I wanted a gun that does Kirin from Naruto (Sasuke's lightning dragon), so I gave it two YouTube links, the anime scene and a short of a railgun mod, and asked it to combine both. It went through both videos frame by frame, wrote the mod for Fabric 1.21.1, modeled the dragon in Blender through the Blender MCP bridge, made the gun model and textures, and then launched the game for me to try it out. The first attempt looked great. I recorded myself using it and sent the video back to Fable for a few small fixes: it fixed the dragon flying upside down, made it 2x bigger, added debris, a proper crater and fire. That was pretty much it. Finished in under an hour, and barely any input was needed from me apart from the initial prompt and that one round of fixes. Output tokens ~383.6k API cost $20.54 Time ~1 hour The mod is free and I uploaded it to github Setup: Fable 5.1 through an Anthropic API key, run inside atomic.chat in agent mode
