Cheapest image generation API prices
Image APIs use three incompatible billing units. The tables keep flat per-image, per-megapixel, and image-token prices separate so unlike rates are never ranked against each other.
Lowest listed flat per-image prices
| Provider | Model | Variant | Unit | Price per image |
|---|---|---|---|---|
| xai | xAI: Grok Imagine Image 2.0 | low_1k | image | $0.040 |
| xai | SpaceXAI: Grok Imagine Image Quality | 1k | image | $0.050 |
Pricing refreshed 2026-08-31. A listed rate may cover only one size, quality, or endpoint variant; confirm the selected variant before buying.
Cheapest video generation API prices
Each model appears once at its lowest listed positive per-second rate. Resolution and audio describe that selected variant; another variant of the same model can cost more.
