Run AI locally: GPU guides

Plain answers to "what GPU do I need to run this AI tool on my own PC, for free?" Each guide quotes the tool's official VRAM requirements with a link to the source, then shows the lowest recorded Amazon US price for a card in each tier.

• Hunyuan3D 2.1: Hunyuan3D 2.1 needs 10GB of VRAM for shape and 29GB for shape plus texture, per its README. See which GPUs fit and their recorded Amazon US prices.
• Wan 2.2: Wan 2.2 video generation: 8GB in ComfyUI for the 5B model, 24GB for the official 720P script. Compare GPUs and recorded Amazon US prices by tier.
