Wan 2.2 TI2V 5B VRAM Requirements
Wan 2.2 TI2V 5B needs about 8.0 GB of VRAM with FP8 weights at 1280×704 and 121 frames, loading one model at a time. In FP16 it needs 12.6 GB (25.6 GB with everything loaded), and GGUF Q4 brings it to 6.5 GB. The smallest consumer GPU that runs it is the RTX 3050 8GB with Q4 weights, or the RTX 3050 8GB in FP8.
8.0 GB peak VRAM
Wan 2.2 TI2V 5B at 1280×704, 121 frames with FP8 weights, loading one model at a time (ComfyUI default on smaller cards). Keeping everything loaded needs 15.7 GB.

About Wan 2.2 TI2V 5B
A compact text-and-image-to-video model with a high-compression VAE, built to make 720p video at 24 fps on consumer GPUs. Its text encoder is larger than the diffusion model itself.
| Component | Size |
|---|---|
| Diffusion model | 5B parameters (Diffusion transformer) |
| Text encoders | umT5-XXL encoder (5.7B) |
| VAE | 0.7B parameters |
| Classifier-free guidance | Yes (2 passes per step) |

Wan 2.2 TI2V 5B VRAM: common questions
Can Wan 2.2 5B run on a 12GB GPU?
Yes at 720p with FP8 weights, the text encoder swapped out after encoding, and tiled VAE decoding.
How much VRAM does Wan 2.2 TI2V 5B need?
At its default 1280×704 and 121 frames: about 12.6 GB in FP16 with model swapping (25.6 GB with everything loaded), 8.0 GB in FP8 and 6.5 GB with GGUF Q4 weights.
