Pricing - OpenAI API - if you noticed, gpt-image-1 falls under text token and image and with difference pricing. And then there is the similar sounding GPT Image 1 that is under image generation. Rather confusing
Yes, all the costs should be collected together in documentation for the image models. Per-model, even.
- prompt text you send
- reference images you send (edits endpoint)
- price increase for higher input quality
- image outputs you receive, by size and output quality
- with exact token consumption at the pricing instead of rounded off pricing
I attempt to collect prices you will pay step-by-step in this post.
That forum topic has not been updated for the reduced output price of the newer gpt-image-1-mini model (just like API documentation itself hasn’t been updated for the model by OpenAI). Any attempt at producing helpful developer info here is futile in the forum format - it quickly scrolls from being found due to all the bugs.
really not sure how to follow you. your post is talking about how it can add up, whereas I’m asking if i want to send an image when is it : treated as text and when image? given that the same api is at 2 places. in fact why would even gpt-image-1 even fall under text?
gpt-image-1 has a cost for text tokens because you send text to an AI model to tell it what to generate.
That computation based on the input tokens has the same consideration as text input sent to the original version of the AI model (based on gpt-4o).
The model also has a cost for “vision” input very similar to the cost if you sent images for understanding to a chat AI model (they are just sized a bit smaller). What is placed is an equivalent to the images’ embeddings, and images also have a convolution step in order to make them understood.
Why does images as tokens cost different than text as tokens, when on normal chat models there is a single token pricing for input (except for audio)? Perhaps because there is also moderation AI independently looking at the images to see if they meet safety requirements? Because there is profit to be had? Anyway, that’s the price.
