I've only managed to get a few prompts to go through, if it takes longer than 30 seconds it seems to just time out. Image quality seems to vary wildly; the first image I tried looked really good but then I tried to refresh a few times and it kept getting worse.

Thanks - this worked for me (some errors, some success).

Last week I was making a birthday card for my son with the old model. The new model is dramatically better - I'm asking for an image in comic book style, prompted with some images of him.

With the previous model, the boy was descriptively similar (e.g. hair colour and style) but looked nothing like him. With this model it's recognisably him.

When I do that, I get two (very similar but not identical) responses side-by-side in one image (I guess as if the model is battling itself?). Is that normal for lmarena?
