Reading the response

​

Multiple images per request

• seedream-4.5 and seedream-5.0-lite support grouped generation. Set sequential_image_generation: "auto" and max_images (up to 4 on seedream-4.5, up to 14 on seedream-5.0-lite). The model returns a group of related images up to max_images and decides the exact count — it may return fewer (a plain prompt often yields one; a prompt that explicitly asks for a set yields several). Use max_images for this, not num_images.
• seedream-5.0-pro does not support grouped generation — it has no sequential_image_generation parameter. Use num_images (1–4) for multiple takes; each is generated and billed independently. It prices by output size (1K = 55, 2K = 110 credits per image) and bills reference_images beyond the first at 5 credits each — see pricing & credits.
• seedream-5.0-flash has no grouped generation either: use num_images (1–4). It costs a flat 25 credits per image at 1K or 2K, and its reference_images (up to 10) are free.

Video generation modes

​

SeeDance 2.5 (flagship)

• Text-to-video — prompt only (aspect_ratio applies here; other modes are adaptive).
• Image-to-video — a start frame (image), optionally with an end frame (end_image).
• Reference-to-video — any mix of up to 15 reference_images (free), up to 5 reference_videos (each 2–15s, 30s combined), and up to 5 reference_audios (30s combined, free; audio-only input works). Editing or extending an existing clip = passing it as a reference_videos entry. Reference media can’t be combined with start/end frames.

​

SeeDance 2.0

• Text-to-video — prompt only.
• Image-to-video — a start frame (image), optionally with an end frame (end_image) to interpolate between the two.
• Reference-images-to-video — up to 9 reference_images to guide the result.
• Video-to-video — supply a video to edit an existing clip. Video inputs are passed by URL (a public URL or one from POST /v1/uploads), not inlined as base64. You can also pass reference_images (up to 6) and/or an audio track alongside the video to guide the edit.

​

MiniMax H3

• Text-to-video — prompt only (aspect_ratio applies here; other modes are adaptive).
• Image-to-video — a start frame (image), optionally with an end frame (end_image).
• Reference-to-video — mix up to 5 reference_images, up to 3 reference_videos clips, and up to 3 reference_audios clips in one request. Clips are passed by URL (public or from POST /v1/uploads); each clip must be 2–15s, with at most 15s combined per media type.

​

MiniMax H3 Max

• Text-to-video — prompt only; aspect_ratio defaults to 16:9. An optional audio URL pins a soundtrack (it replaces the generated audio, trimmed to the video length).
• Image-to-video — image (first frame) and/or end_image (last frame). An end frame on its own is allowed. The output follows the frame image, so aspect_ratio is ignored. audio works here too.
• Reference-to-video — up to 5 reference_images, 3 reference_videos (2–15s each, 15s combined) and 3 reference_audios (2–15s each, 15s combined). Address them in the prompt by order: “Image 1”, “Video 1”, “Audio 1”. aspect_ratio defaults to adaptive (the model picks); an explicit ratio is honored.
• Extend — pass a video (1.6–60s, ≤50MB, aspect ratio between 2:5 and 5:2) and describe what happens next. length_seconds is the new footage appended; the output is the source followed by the continuation. aspect_ratio defaults to auto (keep the source framing); any other ratio crops.

​

Wan 3.0

• Text-to-video — prompt only. aspect_ratio is honored in every mode — an explicit ratio reframes the output even with a first frame or reference media, and the default adaptive lets the model pick a suitable ratio from the inputs and prompt.
• Image-to-video — a first frame (image), optionally with a last frame (end_image) to interpolate between the two.
• Reference-to-video — any mix of up to 10 reference_images (free), up to 5 reference_videos (each 2–15s, 15s combined), and up to 5 reference_audios (15s combined, free). Editing, replicating the style or camera move of, or extending an existing clip = passing it as a reference_videos entry. In the prompt you can address assets by their order in each type: “Image 1 hands Video 1 the guitar…”. Reference media can’t be combined with first/last frames.

​

Wan 2.7

• Text-to-video — prompt only.
• Image-to-video — a start frame (image), optionally with an end frame (end_image) to interpolate between the two.
• Video editing — supply a video and the model applies your prompt to that clip (restyle it, change the scene, alter a subject’s action or the camera move). The video is passed by URL (public or from POST /v1/uploads), not inlined as base64. Up to 4 reference_images may accompany it to guide the edit — for example, supplying the person or style to apply to the clip.

​

P-Video

• Text-to-video — prompt only.
• Image-to-video — a start frame (image), optionally with an end frame (end_image) to interpolate between the two.
• Audio-driven — supply an audio track (MP3/WAV/FLAC) by URL and the model generates video to match it.
