Tencent 13.0 Billion Parameters (DIFFUSION DIT)

Tencent HunyuanVideo 13B (Cinema DiT) VRAM Requirements Guide

Cinema-grade 13B video synthesis Diffusion Transformer with 3D VAE. Ideal for 24GB RTX 3090/4090 (quantized) or 48GB+ rigs.

4-Bit (Q4_K_M) - Recommended
16.41 GB

>98.2% retention. 10.7 GB weights, leaving +7.6 GB headroom on Dual NVIDIA RTX 3060 Rig (24GB VRAM).

8-Bit (Q8_0) - Near Lossless
25.21 GB

Near-lossless 8-bit precision requiring 25.2 GB VRAM for benchmark evaluations.

16-Bit (FP16 / BF16) - Full
41.72 GB

Uncompressed FP16 weights taking 41.7 GB. Demands multi-GPU or datacenter accelerators.

Architectural Memory Breakdown & Attention Scaling

Tencent's Hunyuan Video 13B is a 13.0B parameter open-weights video diffusion transformer engineered for high-fidelity 720p generative video. Pairing dual text encoders (multilingual Hunyuan-CLIP and MLLM) with a 3D causal VAE, native weights and temporal latent buffers consume 21.5 GB in 4-bit precision, serving as the benchmark video workload for 24GB GPUs.

Tier 1 Free Software Optimization ($0)

In ComfyUI or the native Hunyuan pipeline, pass `--fp8_e4m3fn` for text encoders and enable temporal VAE tiling. This prevents out-of-memory spikes during the final 3D latent decompression pass on 24GB graphics cards.

Recommended Hardware Sweet Spot
Dual NVIDIA RTX 3060 Rig (24GB VRAM)

Dual NVIDIA RTX 3060 Rig (24GB VRAM) provides 24.0 GB physical VRAM (+7.6 GB operational margin at 8k context).

Frequently Asked Questions

What GPU is required to run Hunyuan Video 13B locally?

An RTX 3090 (24GB) or RTX 4090 (24GB) is the minimum practical GPU for local generation. GPUs with 16GB VRAM will trigger allocation crashes.

Does Hunyuan Video support image-to-video conditioning?

Yes! Hunyuan Video supports both text-to-video and image-to-video generation, encoding starting frames directly into 3D latent video volumes.
