LTX-Video ComfyUI VRAM & Realtime GPU Cost Calculator
Realtime AI video generation VRAM calculator for Lightricks LTX-Video (2B). Compare RunPod, Vast.ai, and local GPU performance.
Hardware Benchmark & Architecture Analysis
LTX-Video is an ultra-fast 2B parameter diffusion model optimized for near real-time video generation. Base weights take only 9.5GB in uncompressed FP16 and drop to ~6.2GB in FP8. Any 12GB or 16GB GPU runs LTX-Video at high frame rates, with hourly cloud costs as low as $0.12–$0.29/hr on Vast.ai and RunPod.
ComfyUI Pipeline Parameters
Full uncompressed precision. Requires high-end 24GB+ or workstation VRAM.
12GB VRAM Tier
Target: RTX 3060 / 4070
