Collection of GPT-image-generator 2.0 prompting tips, issues and bugs

Yes, the generator is clearly better than 1.0 (probably also 1.5, which I missed). I found the old one especially very boring and uncreative for the kind of motifs I make. The new one is clearly more creative, I still need to see if I can mix forms like with DallE 3.
And yes, the resolution is no longer as fixed. In the first test above, the generator varied the landscape format during generation, that wasn’t in the prompt.
The distortions in the last pass with 1.0 look like a typical refiner effect. I’ve seen this technique in offline models as well. But there are better methods to add details if you modify the latent space directly during generation. 1.0 was boring.
But I can’t really test yet because I constantly have to restart the session.
I don’t have API access, I’m speculating that these error patterns don’t appear in the API?
I hope they fix this quickly, then I can start testing. I have many prompts I want to try and compare.
