ai-media - AI Media Generation

Full-stack AI media generation powered by GPU server (RTX 3090/3080/2070S).

Capabilities

1. Image Generation — Photorealistic images via ComfyUI (z-image, Juggernaut XL)
2. Video Generation — Video synthesis via ComfyUI (AnimateDiff, LTX-2)
3. Talking Heads — Animated talking faces via SadTalker
4. Voice Synthesis — Natural TTS via Voxtral (whisper.cpp)
