CUDA on Linux. Metal on macOS. FLUX, SD3.5, SDXL, SD 1.5, Z-Image, Flux.2 Klein, Qwen-Image, Qwen-Image-Edit, LTX Video & more — no cloud, no Python, no fuss.
mold run "a cat" — that's it. Auto-downloads the model, generates an image, saves to disk.
FLUX.1, SDXL, SD 1.5, SD 3.5, Z-Image, Flux.2 Klein, Qwen-Image, Qwen-Image-Edit, Wuerstchen v2, LTX Video, and LTX-2 / LTX-2.3. Images, native joint audio-video, and quantized variants that fit a wide range of GPUs.
Single binary built on candle. NVIDIA GPUs on Linux via CUDA, Apple Silicon on macOS via Metal. No Python, no libtorch, no ONNX.
Run mold serve on a GPU host, generate from anywhere. REST API with SSE streaming for real-time progress.
Built-in Discord bot with /generate, /expand, /models, and /status slash commands. Run standalone or embedded in the server.
Transform existing images, run multimodal Qwen edit workflows, inpaint regions with masks, and guide generation with ControlNet conditioning. LoRA adapters for FLUX.
Docker images for RunPod and any NVIDIA host. Nix flake, systemd service, NixOS module included.
Local LLM expands short prompts into detailed descriptions. Auto-downloads Qwen3-1.7B, dropped before diffusion runs.
Use mold from OpenClaw as a workspace skill while your GPU server runs elsewhere. Point `MOLD_HOST` at the server and generate from agent flows.
