Z-Vision Generator

Local AI image and video generation — hassle-free and fun. No tangled node graphs, no cloud dependencies, just prompts and results. Runs on macOS (Apple Silicon / MLX) and on Windows and Linux with NVIDIA CUDA through diffusers.

Z-Vision Generator gives you a unified CLI for both image and video generation, with batch runs, prompt variables, LoRA support, upscaling, and more — all while abstracting away platform-specific details.

Features

  • Image generation — text-to-image with Z-Image and FLUX.2 Klein (4B/9B) model families
  • Video generation — text-to-video and image-to-video with platform-specific LTX aliases, audio included by default
  • Cross-platform — automatic backend selection: MLX on macOS, diffusers/CUDA on Windows and Linux for images, and the shared diffusers/CUDA LTX backend on Windows and Linux for video
  • Prompt system — YAML prompt files with variables ({red|blue|green}), structured prompts, snippets, and batch runs
  • Model store — central ~/.ziv/ directory with bare-name resolution, aliases, local paths, and supported HuggingFace model references
  • LoRA support — single or stacked, configurable weights, bare-name resolution (image and video)
  • Image upscale — generate small → Lanczos → img2img refine → CAS sharpen
  • Video upscale — macOS MLX uses distilled two-stage 2× spatial upscaling; Windows/Linux diffusers uses latent upscaling when the model supports it and fails explicitly when it does not
  • Reference images — img2img steering from any starting image
  • Model variants — image quantization across supported image backends, plus macOS MLX video Q4/Q8 aliases
  • Post-processing — contrast, saturation, and CAS sharpening (image only)
  • Interactive controls — skip, quit, pause, and repeat during batch runs (image only)
