When to choose each
Gemini 3 Pro Image
Best for
- Professional image generation and editing
Watch out for
- Pricing differs by standard, batch, flex, and priority consumption
GPT Image 2.5 Flare
Best for
- Fast, high-volume everyday image generation
Watch out for
- OpenAI publishes no per-image price, and its GPT Image 2 calculator does not estimate 2.5 token use, so cost per image has to be measured
- No independent image-quality benchmark is recorded here
