If you're evaluating GPT Image 2 for a project and wondering what it will actually cost to run, the short answer is: $0.03 per image at the base resolution. That's cheaper than the previous generation — and cheaper than most people expect from a model that can render near-perfect text, produce photorealistic product shots, and output at up to 4K.
The slightly longer answer is that the cost scales with the resolution you ask for. Let's break it down.
GPT Image 2 is billed by token usage under the hood — the model processes both text instructions and pixel output as tokens. What you see on hiapi's pricing page is the already-computed per-image price, organized by resolution tier.
Here's the full breakdown as of May 2026:
| Resolution | Multiplier | Price per Image |
|---|---|---|
| 1K (e.g. 1024 × 1024) | 1× | $0.03 |
| 2K | 1.33× | ~$0.04 |
| 4K | 2× | $0.06 |
These are the prices charged through the GPT Image 2 model on hiapi. No hidden fees, no minimum spend.
The base price of $0.03 is roughly 40% cheaper than its predecessor GPT Image 1.5 ($0.05 before it was retired from the platform in June 2026), which had been the workhorse for quick prototyping. GPT Image 2 is faster on cost but slower on generation time (about 107 seconds per image in testing, versus 18–36 seconds for the old model) — so the tradeoff is speed vs. output quality.
GPT Image 2 generates more image output tokens as you increase the requested resolution. More tokens = more compute = higher cost. The relationship is roughly:
The question to ask before picking a tier is: where will this image actually be used?
A common mistake is defaulting to 4K on every call because it sounds better. Unless you're delivering files for print or a large-format display, you're paying double for pixels that will be downsampled anyway.
Going from 4K to 2K saves ~33% per image. Going from 4K to 1K saves 50%. For a batch of 100 images, that's the difference between $6.00 and $3.00 — same model, same prompt quality, just a smaller canvas.
For most web and marketing workflows, 2K is the sweet spot: noticeably sharper than 1K, but only 33% more expensive rather than twice the price.
The token-based billing model means that structuring your prompts consistently — fixed system context, variable product description — can trigger caching on the text input side. The image output tokens are always fresh, but reducing redundant text token charges adds up over volume.
If you're generating variations on a theme (e.g., five color variants of a product shot, or a grid of lifestyle images with the same background), run them in close sequence. You reduce orchestration overhead and can evaluate cost vs. quality across the set before committing to a higher-resolution pass.
GPT Image 2 sits in a different category than budget image models. It was built for commercial-grade output: product photography, marketing posters, brand visuals, anything where text rendering accuracy or photorealism actually matters. At $0.03 per image for 1K output, it's one of the more cost-efficient ways to hit that quality bar on the platform.
If you're running a high-volume pipeline where $0.03 still adds up (thousands of images per day), the gpt-image-2-beta variant at $0.02 per image is worth testing — it trades some output fidelity for a lower price point.
Is GPT Image 2 cheaper than the previous generation?
Yes. GPT Image 2 starts at $0.03 per image (1K resolution), compared to the $0.05 per image its now-retired predecessor GPT Image 1.5 charged. That's a 40% reduction at the base tier, with the 4K output still coming in at $0.06 — competitive even at the top end.
Does resolution affect image quality beyond pixel count?
The model itself doesn't change — it's the same generation capability regardless of resolution. Higher resolution means more pixels, which reveals more fine detail in the output. For images with text, detailed textures, or intricate compositions, the benefit is visible; for simple flat illustrations, the difference is minor.
How is image generation billing different from text generation billing?
Text models typically charge per input + output token, and the cost depends heavily on your prompt length and response length. For image generation, the billing is simplified to a per-image fee determined by the resolution tier — you don't need to estimate token counts. The token math happens on the platform side; what you see in pricing is the final per-image number.
Can I get a cost estimate before generating at scale?
Yes — the pricing table above is exact. Multiply the number of images by the tier price: 500 images at 1K = $15.00; 500 images at 4K = $30.00. There are no tiered volume discounts at the model level, but running at scale on hiapi includes standard API access without per-seat fees.
What if I want to compare GPT Image 2 against other models first?
The Playground on the model detail page lets you test a prompt before committing to batch generation. You can also compare GPT Image 2 against Nano Banana 2 side by side — see the GPT Image 2 vs Nano Banana 2 comparison for a full prompt-by-prompt breakdown with real outputs.
GPT Image 2 costs $0.03–$0.06 per image depending on resolution. For most web-first workflows, 1K ($0.03) delivers excellent results. Jump to 2K or 4K only when output will be printed or displayed at sizes where pixel density is visible.
