⚔️ MiniMax H3 vs Wan 2.2: Open-Weight Video King (2026)
Both are open weights now. One fits a 16GB card today, one generates 2K with native audio if you can feed it. Where each wins, with the VRAM math.

If your GPU has 16GB or less, Wan 2.2 wins this comparison before it starts. H3 became downloadable this week and it's the more capable model — but "downloadable" and "runnable on your card" are different claims, separated by about 26GB.
That's the verdict up front. The interesting part is where the line actually sits, because MiniMax open-sourcing H3 is the biggest thing to happen to open-weight video since Wan 2.2 shipped, and for a slice of readers H3 is now the correct answer.
By the numbers
| MiniMax H3 | Wan 2.2 | |
|---|---|---|
| Architecture | 33B dense, single-stream | MoE: 27B total, 14B active |
| License | Open weights (two hosted-only modules withheld) | Apache 2.0, everything |
| Audio | Native stereo, same pass | None — silent output |
| Max output | 2K, 4–15s | 720p, ~5s per clip |
| Optimized footprint | 42.5GB (from 123.6GB) | GGUF Q4/Q5: ~8–8.5GB |
| Consumer floor | 12GB claimed, heavy offload | 8GB (5B), 16GB (14B GGUF) |
| Render on RTX 4080 | No credible figures yet | 720p in 2–4 min (our rig) |
| Reference inputs | 9 img + 3 vid + 3 audio | Image + LoRA ecosystem |
| Toolchain age | ~1 week | ~1 year |
Hardware: the argument most people should stop at
Wan 2.2's quantized 14B is an 8.5GB download that leaves headroom on a 16GB card, and the full speed stack — SageAttention, TeaCache, Lightning LoRAs — has render times down to minutes per clip. Measured, repeatable, boring. Boring is what production wants.
H3's 42.5GB optimized footprint is a 66% reduction from full precision, achieved by replacing 40% of parameters with a lookup table — genuinely clever engineering, detailed in our local guide. It still doesn't fit consumer VRAM. The ComfyUI team's "runs on an RTX 3060" claim means "swaps through system RAM," and a week in, nobody has published seconds-per-clip on that path. I price it this way: a 48GB cloud card rents for a few dollars a day on the marketplaces, which is cheaper than the 64GB RAM upgrade the offload path wants — and either is cheaper than a 24GB card impulse purchase.
Capability: where H3 is simply ahead
Feed H3 properly and it does things Wan cannot at any settings. Native 2K against 720p. Fifteen-second shots against five. And the one that restructures a pipeline: dialogue, effects and room tone generated in the same pass as the picture. With Wan, sound is a second project bolted onto every clip — voice generation, effects hunting, a mux pass per shot.
The omni-reference system is the underrated half. Nine images, three videos, three audio files to lock a face, a wardrobe, a voice and a camera style in one request. Nothing else open comes close as a single-request consistency scheme.
The asterisks: launch-week testers report character drift on 15-second shots, so the ceiling is part marketing. And the hosted Hailuo app's final 2K polish comes from a regeneration module MiniMax kept server-side — local H3 output won't match the demo reel, a gap our H3 guide covers in detail.
Ecosystem: a year versus a week
Wan 2.2's real moat isn't the base model. It's everything bolted on: GGUF quants at every VRAM tier, Lightning LoRAs cutting steps from 20 to 8, VACE for control, and Wan 2.2 Animate, which transfers a human performance — motion and facial expression — onto any character image.
H3's toolchain is seven days old. Day-0 ComfyUI support with three template workflows is a strong start, and the GGUF conversions are already appearing. But every sharp edge is currently undocumented, and the fine-tune scene — the thing MiniMax explicitly invited by shipping BF16 checkpoints — hasn't produced results yet. Give it a quarter.
Our pick
Wan 2.2 for anyone shipping volume on consumer hardware. It fits your card, renders in minutes, costs nothing per clip, and a year of community tooling has sanded off the edges. It stays our daily driver.
H3 if you have 24GB-plus (owned or rented), your shots need spoken dialogue or synced sound, or you want the strongest open base model to fine-tune. The audio alone justifies the hardware bill for talking-head and dialogue work — that's the workload where Wan's silence costs you 40 minutes of post per minute of output.
How we compared: H3 figures from MiniMax's release documentation and the ComfyUI day-0 announcement; Wan figures from our own RTX 4080 pipeline and the community benchmarks cited in our setup guide. No head-to-head render times appear because honest local H3 numbers don't exist yet — when they do, this page gets updated with them.
Six months ago "best open video model" had one answer and it was 14B and silent. Now a 33B omni model with stereo sound is sitting in a Hugging Face repo, and the fine-tunes built on it will decide whether next year's comparison is even close.
Frequently asked questions
▸Which one runs on a 16GB card?
Wan 2.2, comfortably — the GGUF-quantized 14B fits with room for the text encoder, and the 5B variant runs on 8GB. H3's optimized footprint is 42.5GB; on 16GB it exists only through aggressive system-RAM offloading that nobody has published honest speed numbers for yet. On consumer VRAM this comparison has a default winner.
▸Does Wan 2.2 generate audio?
No. Every Wan output is silent, and sound is a separate pipeline — voice model, effects, and a mux pass. H3 generates dialogue, effects and stereo ambience in the same pass as the picture. That single difference explains most of the reason to endure H3's hardware demands.
▸Is MiniMax H3 actually open like Wan is?
The weights are downloadable and fine-tunable, which is real. Two hosted-only pieces stayed behind: Context-IR for long-context consistency and the 2K regeneration module the Hailuo app uses for final polish. Wan 2.2 ships everything under Apache 2.0. Wan is the cleaner 'open' — H3 is the bigger model.
▸Which is better for consistent characters?
H3's reference system takes up to 9 images, 3 videos and 3 audio files and is the strongest consistency input scheme on any open model. Wan counters with ecosystem: character LoRAs and Wan 2.2 Animate, which transfers an acted performance onto your character. Single-shot likeness: H3. A repeatable character pipeline: Wan, today.
