It's hard to find the model used for images that are uploaded from Twitter/Pixiv unless the artist has specified it in their page/it's a self upload, or if the metadata is included.
The metadata here does exist but I can't find anything about a model called "Chiruchiru7" so it might as well just be a private model. But anyway, keep in mind that the uploader who uploaded a Pixiv/Twitter image most likely won't have an idea of the model used unless they already added it.
I have seen a few AI images from Dall-E 3, it seems it can generate text more consistent and readable. Still has some problems but some images are impressive.
It does look really nice, the only issue would be the fingers on one hand with the little finger being too big. The image size perhaps could be bigger but I don't think that's decisive.
Same btw, I'm also in "pending" for a lot of uploads
