Frequently asked questions
+How much does GPT Image 2 cost compared to FLUX.2 [dev]?
GPT Image 2 costs $0.24 per image while FLUX.2 [dev] costs $0.04, so GPT Image 2 is six times more expensive. Generating 100 images costs $24 versus $4 on FLUX.2 [dev].
+Can I test both models on the same account?
Yes. Both are available through /tools/flux-2 and /tools/gpt-image on one ManifoldGen key and credit balance, so comparing them on your own prompts costs only the per-image credits.
+Which model is better at following detailed instructions?
GPT Image 2 has the strongest instruction following on ManifoldGen, which is what the $0.24 premium buys. FLUX.2 [dev] adherence is strong for typical creative prompts but loosens on long multi-constraint briefs.
