When to choose each
FLUX1.1 [pro]
Best for
- Hosted FLUX text-to-image generation
Watch out for
- No exact compatible public benchmark snapshot is recorded
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
