Model selection guidance

  • Use veo31_lite for the lowest Veo 3.1 cost profile (40 credits) in text-to-video and image-to-video flows.
  • Use veo31_fast when speed and predictable 8s output matter most.
  • Use kling_3_0 for flexible durations, quality modes, and frame controls.
  • Use wan_2_6_v2v for source-video remix workflows.
  • Use hailuo_2_3_* only when you can provide a reference image.
  • Use sora_2_pro_storyboard for multi-shot storyboard planning flows.
