It's legit, just variations / iterations.

Here's what I got for "A still of Kermit The Frog in Blade Runner 2049 (2017)":

None of them scream Blade Runner 2049 to me.

In this case its the overall "tone" and color palette. Very uniform diffuse lighting, muted color, etc.

? Dale is a legit project from openAI

I think "legit" in this context might mean more of the Twitter post author's representation of their use of DALL-E 2:

- Were the prompts shown the ones fed to DALL-E 2 or were there more complex details described in the prompt?

- Were these the first images generated for the prompt, or did the author generate many images and cherry-pick the best example, and if so from how many?

The second one is how everyone does it, by the way. AI may as well be a cherry orchard. There’s nothing wrong with it.

The first one, I’d have a huge problem with. Lying about prompts is a no no. Thankfully there’s not much incentive to lie.

That doesn't mean the images in this tweet thread are output from Dalle though…

Although if an individual created all of these then that's about the same amount of impressive

It's funny that 10 years ago "a human did it" would be, by far, the most plausible explanation. Today, it's "AI did it." Put another way, if a human made these then it'd be as shocking as seeing DALL-E 2 in 2012.
