Pricing checked against provider documentation on . How we verify
The short answer
Ideogram 4.0 Turbo is the cheaper option — roughly 1.4x less on a blended workload, and it suits legible text inside images. GPT Image 1.5 justifies its premium when you need complex multi-subject composition.
Ideogram • Ideogram 4
$0.03 / $
/ image (input / output)
Ideogram's differentiator is typography: text rendered into an image that stays readable and correctly spelled, which most diffusion models still handle badly. If your output needs a logo, a sign, a poster headline, or packaging copy, this is the specialist worth testing first.
OpenAI • GPT Image
$0.04 / $
/ image (input / output)
The strongest current model for scenes with many interacting elements — independent testing puts it ahead of the FLUX line on photorealism and well ahead on compositions involving eight or more subjects. Latency is around five seconds, so it is a considered choice rather than an interactive one.
Input price
GPT Image 1.5 is 40% more expensive than Ideogram 4.0 Turbo on input tokens.
