GPT Image 2.5 API price per image
Rendergrid’s price per image for GPT Image 2.5, GPT Image 2.5 Sunburst, and GPT Image 2.5 Flare, why OpenAI quotes tokens, and how to plan a budget.
OpenAI models
5 GPT Image models. GPT Image 2 and GPT Image 2.5 generate only at 1K; GPT Image 2 HD, GPT Image 2.5 Sunburst, and GPT Image 2.5 Flare generate at 1K, 2K, and 4K. All accept up to 14 reference images; there is no auto mode.

Model pageAll 5 models: up to 14 reference images (PNG, JPEG, WebP), default resolution 1K; there is no auto mode, so without aspect_ratio the aspect ratio is 1:1. A 2K or 4K request to GPT Image 2 or GPT Image 2.5 gets a 400 response before any charge; GPT Image 2 HD, GPT Image 2.5 Sunburst, and GPT Image 2.5 Flare generate at 1K, 2K, and 4K.

Models side by side
Resolutions, aspect ratios, reference images, price, and average time over 7 days. The name links to the model page.
| Model | Maker | Resolutions | Aspect ratios | Reference images | Price from | Time |

GPT Image 2.5gpt-image-2.5 | OpenAI | 1K | 13 | up to 14 | from $0.025 | 35 s average |
Aspect ratios are counted without auto: it is available on 4 Google models; Nano Banana 2 Lite doesn’t have it. The price depends on the resolution; the full table is on the “Pricing” page.
03FAQ
Questions about models
Which resolutions do OpenAI models have?
GPT Image 2 and GPT Image 2.5 are 1K only: a 2K or 4K request gets a 400 response before any charge. GPT Image 2 HD, GPT Image 2.5 Sunburst, and GPT Image 2.5 Flare generate at 1K, 2K, and 4K. The default resolution for all of them is 1K.
How many aspect ratios does each model have?
GPT Image 2: 10, GPT Image 2 HD: 10, GPT Image 2.5: 13, GPT Image 2.5 Sunburst: 8, GPT Image 2.5 Flare: 8. There is no
auto mode: if no aspect ratio is given, it is 1:1.How much cheaper is this than OpenAI’s official prices?
How do GPT Image 2.5 Sunburst and GPT Image 2.5 Flare differ?
Their resolutions, aspect ratios, and price are the same; GPT Image 2.5 Sunburst is built for precise handling of fine detail. The easiest way to compare them is on your own prompt: every model page has a playground.
Do I need a separate OpenAI account?
No: one Rendergrid key and one balance for all models; you choose the model with the
model field.04Articles
