FAQ

About Wan 2.6 Flash API

Wan 2.6 Flash mirrors Wan 2.6 parameters (modes, resolutions, duration ranges, multi-shot, audio, negatives) but is tuned for faster generation and lower price.

Same surface area in the playground. Expect different latency and pricing. Pick Flash when throughput matters most and standard Wan 2.6 when you default to that tier for policy or billing reasons.

720p and 1080p, matching non-Flash Wan 2.6.

The Generate Audio toggle defaults to true in the playground so clips include model audio unless you disable it.
