Frequently asked
Quick answers to common questions
How much VRAM does HunyuanVideo 1.5 need?
HunyuanVideo 1.5 with 13B parameters needs significant VRAM depending on quantization. Use our VRAM calculator for an exact estimate.
Is HunyuanVideo 1.5 better than other Hunyuan models?
HunyuanVideo 1.5 has 13B parameters with 8,192 context - a strong choice for text-to-video.
What license is HunyuanVideo 1.5 under?
HunyuanVideo 1.5 is released under the Apache 2.0 license, making it suitable for most commercial and personal projects.
What hardware runs HunyuanVideo 1.5 well?
With 13B parameters, HunyuanVideo 1.5 requires adequate VRAM. High-end GPUs like the RTX 4090 (24GB), RTX 5090 (32GB), or Mac Studio with unified memory are good options. Check our hardware directory for specific recommendations.
What is the best quantization for HunyuanVideo 1.5?
Q4_K_M is the recommended sweet spot - ~98% of FP16 quality at ~27% of the size. Step up to Q5_K_M or Q8_0 only if you have spare VRAM. Use our VRAM calculator to compare.
