which Ai Model do you suggest for stock photos

Right. And they need fixing in Photoshop or follow-up edits using AI. If that's not possible, assign the assets to the trash. I've been doing text to image AI for over 3 years. I've probably generated somewhere in the area of 200,000 assets, of which I've kept only around 15,000, many of which were (or will eventually be) edited to be suitable for stock. 

Are you editing the results? Even Nano Banana assets require anywhere from some to extensive editing. In the past three years, I estimate I've generated over 200,000 text to image AI assets using various models. I've only kept about 10 to 15 thousand of those deemed good enough to spend time post-processing. The top image was a Nano Banana result. The bottom image was the result of editing sections at a time (also using Nano Banana and Photoshop) to achieve an asset worth submitting. This is an extreme example, but I've yet to get a result that didn't require a few minutes or a few hours post-processing.
