The One-GPU Claim
Wan 2.1 (16,810 stars on the official repo, fetched 2026-08-13) was the first open video model that felt practical. Wan 2.2, released in 2025, is the version that made the claim concrete: the 14B T2V and I2V models can run on a single 24 GB consumer GPU with quantization, and the 5B model family runs on far less. For people without access to rented clusters, this changed the math.
What 2.2 Changed
- Smaller model family: the 5B models are designed for consumer hardware and fast iteration, while the 14B models keep the quality crown.
- Better motion: 2.2 improved temporal consistency - objects stay stable across frames, the failure that made earlier clips feel like morphing.
- Stronger text rendering: video with readable text (titles, signs) was a classic failure; 2.2 handles it much better.
- I2V maturity: image-to-video with a reference image is now the headline workflow for product and creator use.
Running It on One GPU
The practical 2026 path is ComfyUI (127,047 stars) with the WanVideo wrapper nodes:
- Install ComfyUI plus the WanVideo custom nodes.
- Download the GGUF-quantized 14B (for 24 GB) or the 5B (for 8-12 GB) weights.
- Start with 480p, 5 seconds, 24 fps - the settings that fit in VRAM and iterate fast.
- Keep prompts to one clear subject-action pair; video models amplify prompt ambiguity into motion artifacts.
Wan 2.2 vs HunyuanVideo 1.5
| Dimension | Wan 2.2 | HunyuanVideo 1.5 |
|---|---|---|
| Consumer GPU | yes (5B/quantized 14B) | tight (needs heavy quantization) |
| Motion realism | very good | very good |
| Text in video | strong | good |
| Ecosystem tools | ComfyUI wrapper mature | ComfyUI support good |
| Best for | single-GPU creators | quality-first with rented GPUs |
Both are serious tools; the honest summary is that Wan 2.2 is the better default for a single-GPU workflow, while HunyuanVideo remains the pick when you have the hardware to feed it.
The 2026 Workflow
- Draft with the 5B model at 480p - seconds per clip, cheap to iterate.
- Validate prompt and motion on the draft.
- Re-render the keeper with the 14B at 720p.
- Use image-to-video for anything where composition matters - a still you control beats a prompt you gamble on.
