Dated 2026-10-22: Gemini 3.1 Flash Image $0.067 per 1K image (token-based, $60/M image tokens, 1,120 tokens); OpenAI gpt-image-2 per-image table $0.006/$0.053/$0.211 (low/medium/high, 1024x1024) with a token rate of $30/M output tokens; Runway gpt_image_2 1/5/20 credits per 1K image; Stability Stable Image Ultra 8 credits ($0.08); Replicate flux-1.1-pro $0.04 per output image; Luma Uni-1.1 about $0.04 per 2K image (two price columns, second is Max). Image prices are quoted per image, per megapixel, per credit or per token, and OpenAI states equal token rates do not mean equal cost per image.
