Credits are charged per generation. Video cost scales with duration, image cost with resolution and
image count. Failed generations are never charged.

durations and resolutions, and the credit-cost table below to compare costs.
Video model reference
default resolves to kling-3.0 on paid tiers and ltx-2.5 on the free tier. Free typically
requests 480p; paid plans (Creator, Pro, Business) can request the higher resolutions a model
supports, at that resolution’s credit cost. The deprecated kling-2.5-audio and veo3.1-audio
values are equivalent to passing the base model with audio: true.Video credit costs
Credits per second of output. For text-to-video and image-to-video, multiply byend_seconds to estimate a job.
For endpoints that trim an input, the clip duration is end_seconds - start_seconds.
The video formula is
duration × output fps × resolution multiplier. Because output fps varies by
model, two models at the same resolution can cost different amounts per second.
Legacy model values
The endpoints still acceptltx-2, kling-2.5, kling-1.6, seedance for backwards
compatibility, but these are no longer recommended and are absent from the tables above. New
integrations should use a documented model.
AI video editor has its own roster:
gemini-omni-1.1 and ltx-2.3, defaulting to ltx-2.3 on the free tier and gemini-omni-1.1 on paid
tiers. The deprecated gemini-omni value is equivalent to gemini-omni-1.1.
Image models
Available on AI image generator and AI image editor.
“From” is the cost of a single image at the model’s lowest resolution. Higher resolutions cost more,
and generating multiple images multiplies the cost. Free-plan image models are available at
640px.
Larger resolutions require a paid plan even if the model is available on the free plan.
Reference costs
These endpoints use tool-specific pricing. Some rates vary by resolution or output settings.AI Image Upscaler
Cost depends onstyle.mode and scale_factor.
Duration-based endpoints
These charge by output length rather than per generation.Video jobs return an estimate in
credits_charged on the create response. The final amount is
corrected once the render finishes and the true frame rate is known. Read credits_charged from
the get-details response for the actual charge.Estimating before you build
