About

bitGen Studio - a local AI video, image, music and editing studio. Everything runs on your own computer: no sign-ups, no cloud.

Tiger Art

Tiger Art is an independent software studio in Australia. bitGen Studio is what we make: a whole film studio that runs on the computer in front of you, so the work, the files and the choices stay yours.

It is free and open source under the MIT licence. Every line is on GitHub - read it, change it, and send improvements back.

Thank you

bitGen Studio stands on the work of many people. Thank you to everyone below - the projects whose code, models, ideas and tools we use or learned from.

Generation engines

  • ComfyUI by Comfy Org and comfyanonymous - the generation engine - every image, video and music style runs as a ComfyUI graph; its own frontend's graph conversion is mirrored for workflows
  • comfy-kitchen by Comfy Org - the int8 ConvRot weight layout, re-implemented in the native engine (Apache-2.0)
  • llama.cpp by ggml-org - the local LLM (llama-server) behind ✨ Enhance, the prompt chat, screenplays and the vision captioner
  • stable-diffusion.cpp by leejet - the first image and video backend (sd-cli)
  • Hugging Face diffusers by Hugging Face - the MiniMax H3 weight conversion and modular pipeline the native engine follows (Apache-2.0)
  • Hugging Face Hub by Hugging Face - where the model files come from
  • FFmpeg - compiling, exporting, proxies and every audio / video conversion

Video models

  • MiniMax H3 by MiniMax - the main video model - text, references, first / last frame, native audio
