60 images for a a 60-shot storyboard: GPT Image 2.5 cost by quality

60 images at 1024x1024 cost $1.4850 at quality: low, $3.3375 at medium and $13.3425 at high with ChatGPT Image 2.5 (openai/gpt-image-2.5) on Sume. That is one image per request, priced from Fal's output-token rates with Sume's margin.

Sume's Image API docs (read 2026-10-06) say that if you omit quality the default is high, and that auto reserves the max price. For a a 60-shot storyboard, pass the quality you mean.
