Questions, answered.

Can I use this model now?

No. This is an early-access contract preview. Join the waitlist to request access; no generation or payment is available now.

What does this preset generate?

Hailuo H3 is configured for 5-second output at 768p, with native audio. Only text prompts and 16:9 or 9:16 aspect ratios are accepted initially.

How much will this model cost?

Coming soon. A price is published only after the preset cost and a lower-than-kie.ai quote are both verified. Early-bird rates apply after access opens.

Can I send arbitrary provider parameters?

No. The initial contract accepts only model, prompt and aspect_ratio. Other fields are rejected rather than silently forwarded.
