How to compare GPT Image API prices
Compare GPT Image 2, 2.5, and 2.6 at the same size and quality.
Match the output specification
Fix the aspect ratio, resolution, quality, and number of outputs before getting prices. Record each variant separately because the same quality label can have a different price across versions.
Budget edits separately
Quote the real edit with the intended number of reference images. Divide the total cost by accepted outputs, then check the billed amount after the job.
