Video generation

MiniMax H3

H3 is a next-generation open-weights, general-purpose multimodal video model. Rather than being limited to specialized tasks such as generating, editing, or referencing, H3 understands multimodal contexts that bring together text, images, video, and audio. This enables it to interpret creative intent in a unified way and deliver more natural, coherent generation and expression.

Retries are off, so a dropped connection cannot start a second job. The MP4 stays available for 24 hours after the job completes.
