Frequently asked questions
Which is cheaper, GPT Image 2.5 Flare or GPT Image 2.5 Sunburst?
GPT Image 2.5 Flare and GPT Image 2.5 Sunburst start at the same price, $0.01 per generation, so the choice comes down to capabilities rather than cost.
What do GPT Image 2.5 Flare and GPT Image 2.5 Sunburst cost for 1,000 generations?
1,000 generations cost $10.00 on either model.
What can GPT Image 2.5 Flare do that GPT Image 2.5 Sunburst cannot?
Their published capabilities match, so the practical differences between GPT Image 2.5 Flare and GPT Image 2.5 Sunburst are price and the parameters each accepts.
Do GPT Image 2.5 Flare and GPT Image 2.5 Sunburst take the same parameters?
Yes — both accept the same 4 parameters, so a request body written for one works on the other with only the model id changed.
Can I switch between GPT Image 2.5 Flare and GPT Image 2.5 Sunburst?
Yes. Both run behind the same API Stock endpoint, so switching means changing the model field in the request body. The same API key and the same prepaid balance cover both, and there is nothing else to migrate.
