OpenAI GPT Image 1.5
GPT Image 1.5 — OpenAI Quality from 20 Credits
OpenAI’s December 2025 speed play: 4x faster generation, edits that preserve faces and logos, at the lowest OpenAI price here.
GPT Image 1.5 is OpenAI’s image model from December 16, 2025, released as the new engine behind ChatGPT Images. It generates up to four times faster than GPT Image 1 and edits with unusual restraint: it changes what you asked for and preserves faces, logos, lighting, and composition. At 20 credits per 1K image, GPT Image 1.5 is the cheapest way to use an OpenAI image model on this platform.
What is GPT Image 1.5?
OpenAI shipped GPT Image 1.5 during its late-2025 push on image quality, and it reset the ChatGPT Images experience: four times faster than its predecessor, with denser and smaller text rendered correctly and a 20 percent API price cut that our 20-credit price reflects.
The editing behavior is the quiet strength. Ask for one change to an uploaded photo and the model applies exactly that change, keeping people’s faces, brand logos, lighting, and layout consistent through the edit and across follow-up edits. For iterative photo work, that predictability matters more than raw quality.
It sits between the two other OpenAI models here. Versus GPT-4o Image (30 credits, three-to-five-minute waits), it is faster, cheaper, and sharper on text. Versus GPT Image 2 (30 credits, up to 4K, eight ratios), it gives up resolution and format range but costs a third less at 1K.
On Nano Banana AI, the 1K tier runs standard quality at 20 credits; the 2K tier runs the model’s high-quality mode at 110 credits, which reflects OpenAI’s own steep price step for that mode. Three aspect ratios are available: 1:1, 3:2, 2:3.
