That doesn’t make any sense.
You are talking about compression, not resolution.
Bing images are JPG compressed with the default (non-progressive) honeycomb algorithm, but almost with JPG factor 80 which is extreme high.
I recommend a simple command line tool like ExifTool
to fetch those meta-data - ExifTool by Phil Harvey.
Dall-E spits out lossless compressed (not lossy, like JPG) PNG files; but in the end the are (almost) the same.
It’s like an 320kbps mp3 file, compared to FLAC.
I work as an audio-engineer and can’t even hear the difference.
For both Bing and Dall-E you can use free / open source (just check Git and some repos) upscalers.
I managed to upscale images to 300DPI at 5 square feat (1.5 meters) in size, created by both Bing and Dall-E.
BTW. both Bing and OpenAI explicit state that you are allowed to use the images for any commercial purpose.
It’s your prompt, your image, they only provided the software. It’s just a tool, like Photoshop.
Q: Can I use Bing Image Creator for commercial projects? Yes, Bing Image Creator allows commercial use of AI-generated images. However, it is essential to check the licensing terms for each image to ensure compliance.
At least in Europe and the USA an AI can’t have any rights on “it’s” work, it’s not an entity that has intellectual PO (private ownership).
But there are “issues” when the source of the image is copyrighted (like cartoon characters).
