Wan 3.0 vs HappyHorse 1.1

Pick Wan 3.0 when…

• The clip is a final deliverable and 8 extra credits per render is not the constraint
• You have settled on the shot and are rendering the version that ships
• The brief leans on cinematic

Trade-off: You pay 8 more credits on every generation; You wait 15s longer per clip.

Pick HappyHorse 1.1 when…

• You are generating in volume and the 8-credit difference per clip adds up fast
• You are still exploring and need a tight generate-judge-regenerate loop (~55s / 5s clip versus ~70s / 5s clip)
• The brief leans on dynamic motion

Trade-off: Output characteristics differ, but neither model gives up a hard capability to the other.

Vendor angle

Both models come from Alibaba, so you are choosing inside one vendor's interpretation of video generation rather than across two philosophies. That usually means the motion signature is similar and the difference is mostly cost, latency and clip length — which makes the cheaper or faster one the sensible default for volume work.

What it costs to decide

Running one clip on each costs 72 credits in total (40 + 32). A new account starts with 40 free credits, which covers HappyHorse 1.1 plus part of the other — enough to run a real comparison rather than reading about one. Paid plans start at 600 credits per month, and there is no per-model subscription: one balance, 22 models.
