falcraft
by shikamaru
Falcraft is a Fabric mod that generates 3D structures from short text prompts, such as a majestic medieval castle, through the fal.ai service.
What it does
A player types a simple prompt and the mod sends that text to fal.ai, which builds a 3D model of a castle, character or other structure. Results usually arrive in about 30 seconds, after which a ghost preview appears in the world. Pressing G rotates the preview and right-clicking places it. Only the text prompt is transmitted, and the mod's own README points to fal.ai's privacy policy for how the service handles that data.
Generation needs a fal.ai API key with credits configured in the mod, because each call is billed by the provider. The mod's notes put a single structure at about $0.025 to $0.03, regardless of the Minecraft size chosen, and list 33 to 40 structures per size at the lower price point. The service runs the models on its own high-end GPUs, so the mod itself stays light on the player's machine. Files are published for Fabric only, for Minecraft 1.21.1, and the mod is licensed CC0 1.0 Universal, which places it in the public domain and is not open source.

Quick scenery for creative builds
Builders who need a few large pieces of scenery can generate them from prompts instead of building each one by hand.
