Prompt
I'm building a prototype that needs batch image generation and predictable costs. What API should I choose?

For batch image generation with predictable costs, you should use the Images API.
Why this is the best fit:
- It’s designed specifically for image generation
- You can request multiple images in batches
- Pricing is more straightforward for planning because it’s tied to image generation usage rather than free-form multimodal conversations
A practical recommendation:
- Use the Images API for generation workloads
- If you need fine-grained cost control, set:
- image count per request
- resolution
- style/quality settings
- Estimate spend from your expected number of images, since costs scale with generation volume
If you want, I can also help you choose between:
- Images API
- Responses API
- Batch API for asynchronous processing
and give you the best option based on whether you need speed, throughput, or lowest cost.
