HunyuanVideo

HunyuanVideo is Tencent's large open-source text-to-video model, built as a full-attention transformer rather than the more compute-efficient architectures some competitors use. That architectural choice buys quality — 1280x720 output with strong visual fidelity for around 5-second clips — at the cost of hardware demands: you need 60GB or more of VRAM to run it, which in practice means a multi-GPU rented setup, not a single consumer card. It's free to download and use (no per-clip fee), and like Wan 2.2 it's typically run through ComfyUI. For a student, HunyuanVideo is worth knowing about as the 'high-end open' option — useful if you're already renting serious GPU capacity for other work (training a model, running a large LLM locally) and want to add video generation to the same rig, but Wan 2.2 or LTX-Video are more practical starting points given the lower hardware bar.
