GPT Image 1.5
GPT Image 1.5 costs $0.024/image on FairStack — a text to image model for Marketing images with text, Precise prompt adherence, Quality-sensitive workflows. That's 76% less than Midjourney. No subscription required. Pay per generation with full REST API access. FairStack applies a transparent 20% margin on infrastructure cost so you always see the real price.
What is GPT Image 1.5?
GPT Image 1.5 is OpenAI's flagship image generation model, currently ranked #1 globally by Elo score across major benchmarks. It excels at precise prompt adherence, following complex multi-part instructions more faithfully than any competing model. Its text rendering capabilities are best-in-class, generating clean, readable text directly within images — a historically difficult challenge for AI image models. The model offers three quality tiers: low ($0.009/image), medium ($0.02/image), and high ($0.11/image), allowing users to optimize for speed or detail depending on their workflow. High-quality outputs support up to 2048x2048 resolution, and a seed parameter enables reproducible outputs across generations. Compared to alternatives like Midjourney or DALL-E, GPT Image 1.5 stands out for its instruction-following precision and text rendering accuracy. Where other models approximate text or struggle with multi-element compositions, this model delivers consistent results on the first attempt. GPT Image 1.5 is the recommended choice for marketing images containing text, product mockups requiring exact specifications, and any workflow where prompt accuracy is the primary concern. On FairStack, it is available at infrastructure cost plus a 20% platform fee.
