Official examples from the model vendor: Alibaba.

Wan 3.0 is Alibaba's August 2026 video model. It generates 2 to 30 second clips in a single pass at 480P, 720P, 1080P, 2K or 4K, with an audio track by default. Inputs go beyond images: text, first and last frames, up to 10 reference images, and up to 5 reference videos and 5 reference audio clips (each 1-15 s, 15 s in total). Alibaba also accepts a document or a public web page as input, but Jantaris does not expose that option yet. Prompts can be up to 20,000 characters.

Best for

  • Product videos built from several reference photos
  • Music videos with a character and voice from your references
  • 30-second 4K ads in one pass
  • Scenes that combine several characters, clips and voice references

Prompting tips

  • Refer to assets by name in the prompt: "Image 1 walks into the room from Video 1 while Audio 1 plays".
  • duration: -1 lets the model pick the length but bills 30 seconds, so set a number when budget matters.
  • Reference videos are billable; keep them short and within the 15-second total.
  • The default resolution is 1080P; switch to 480P for drafts.
