I am using the https://api.openai.com/v1/images/generations to generate DALL-E images via API.
The response could be either image URL, or base64 image.
I chose the Image URL, and I was able to download it with: wget -O image.png <API_RESPONSE_URL>
to my local disk.
This is al fine, but I am wondering, if someone knows, how long will be the image URL valid. I mean how long is his lifetime on the OpenAI server.
Reason why I am asking, that I want to store these URLs in my database (instead of keeping the 4+MB base64 images) , so if there is no expiration on these URLs, I can simply store that URL in my database and save a TON of disk space on my server.
If it’s like you telling, then I will save few cents, and generate the 512x512 size images, fetch them as a base64 image, then convert it to webp or even avif format with lower compression directly on my server and it will also save my disk space
I have a dedicated server with approx 800GB free space, which is enough to store ~180k images at 1024x1024 resolution, which will cost me around 3000$ . These images are really fantastic and I want to create a web-gallery of them.
Of course I will not type manually all of 180k crazy ideas, I’ve created a really cool randomizer which is asking AI-like request directly to DALL-E API . So it will be like: “My AI is asking DALL-E API” , they are having a chat, and I am just watching the output haha.
Thanks @PaulBellow for your quick answer! Have a nice day!
I have an app which prompts Dall-E for images @Fanta and had the same problem you encountered with (rapidly) expiring OpenAI links to these images.
So, what I do when I make this API call is to immediately download the image to the filesystem (where it is also available via the web, naturally) as follows:
# saves a url genereated by dalle to a file
File.open(file,"wb") do |file|
I also have a bit of code to take the locally stored image file URL and convert it to a short url, but that’s just a bit of coding window dressing and not really necessary.
