Kling 2.1kling/v2-1-standard, kling/v2-1-pro, kling/v2-1-master-text-to-videoStandard and Pro are image-to-video only; Master is text-to-video only.
Sora 2sora-2-text-to-video, sora-2-pro-text-to-video, sora-2-image-to-videoDuration- and resolution-dependent pricing.
Hailuo 02hailuo/02-text-to-video-standard, hailuo/02-text-to-video-pro, hailuo/02-image-to-video-standard, hailuo/02-image-to-video-proStandard/Pro pricing differs mainly by duration tier.
Veo 3.1veo3_fast, veo3, veo3_liteFlat-rate 8-second clips. Supports both text-to-video and image-to-video.
Wan 2.6wan/2-6-text-to-video, wan/2-6-image-to-videoDuration and resolution both affect credits.
Seedancebytedance/seedance-1.5-proSupports both text and image input modes; duration and resolution affect credits.

Input mode rules

  • Models ending in -text-to-video require inputMode: text_to_video.
  • Models ending in -image-to-video require inputMode: image_to_video and at least one inputImageUrls entry.
  • Veo 3.1 (veo3_fast, veo3, veo3_lite) supports both modes.

Field notes

  • duration is model-specific. Common allowed values are 5, 10, 15, or 20; Veo is fixed at 8.
  • inputImageUrls currently feeds the first image into the video provider path. Keep the array focused on the exact frame you want animated.
  • aspectRatio and provider-specific controls vary by model family.
  • For exact per-model credit numbers, see Pricing.

Video tasks typically complete in 30–120 seconds depending on model and duration. The same polling loop used for images applies.
