AI Builder 0.1.0
AI Builder 0.1.0
The first release: build and edit structures by chatting ("build a small castle", "add a tower on the east side") or from a reference picture, with a model that runs on your own PC, your own local server, or your own Claude or OpenAI key.
Needs BlockDesigner 0.4.17 or later (plugin API 5).
Install: download ai-builder-0.1.0.jar below, then in BlockDesigner open Plugins (puzzle icon) › Manage plugins… › Install… and pick it. The Assistant and Models pages appear in the plugin's tab on the right. Later versions install themselves if Update plugins automatically is on.
New
Assistant
- Chat to build: ask for a build or a change and the reply streams in, a short plan and then the commands it ran, each with a tick or a cross under the answer.
- What it works on: the selection, everything visible, or a new layer of its own for a new build. The line under the controls says which.
- One undo step per answer: Ctrl+Z or Undo this takes it back. Stop ends an answer at once without changing anything.
- Tries before it changes anything: commands run on a copy of the scene first, and failed lines go back to the model to fix, up to three times.
- Styles: medieval, rustic, desert, nordic, fantasy and modern palettes, or let the assistant pick.
- Reference pictures: attach or drop a picture. Models that see pictures get it; every model gets its main colours matched to building blocks.
Models
- Built-in models on your PC: Gemma 4 E4B (recommended, 5.2 GB), Qwen2.5-VL 3B, Qwen3-VL 8B and Gemma 3 12B, with their size, memory needs and licence. Downloads show speed and time left and resume where they stopped. Any GGUF model from Hugging Face can be added too.
- Engine: llama.cpp, downloaded the first time, for your graphics card, CPU only or NVIDIA CUDA, falling back to the CPU build if the graphics card one won't start.
- Background model: Stopped, Starting or Ready, with Start and Stop, start when BlockDesigner starts and stop when unused. It stops when the plugin is turned off or BlockDesigner closes.
- Your own AI instead: a local server (Ollama, LM Studio or any OpenAI-compatible address), or your own Claude or OpenAI API key, stored encrypted for your Windows account.
Builder commands for BlockEdit
/setblockand/fillas in Minecraft, with block mixes such as70%stone_bricks,30%mossy_stone_bricks./tower,/roof,/battlements,/windows,/door,/gatehouseand/floorslay whole parts with stairs and slabs facing the right way. They work in the command bar (T or /) as well as for the assistant.
Good to know
- This is a first release, so expect rough edges; small local models make simpler builds than big ones.
- The built-in model is a one-time 5.2 GB download (plus the engine), offered the first time you open the Assistant page. With it, or with your own local server, nothing leaves your PC.
- Claude and OpenAI need your own API key and are billed to your account. With a key, the scene summary, your messages and any attached picture go to that company.
