test v3 (1K)
good
good
I do not know what to say, it is all good as expected

and the last one for this test
Nano Banana do pareidolia effect. It is one of the few models that able to.
Star Wars themed meme "Ai need more datacenters" - Censored.
ERROR Cloud: model="gemini-nano-banana-2.1" no images receivedtest v2 (1K)
row 1 - all good
row 2 - it is kind of perfect. like shoes brand visible, pen on a signature. skin, eye.
row 3 - same there. Everything you ask for is generated as you expect it to be.
row 4 - reflection trap is ok, car passengers not perfect, other is good
nature is good
ChatGPT Images will probably add a lot of details. At least Critic background. Gemini will not. ok.
Hmm.. 3 arms on wall break. So, the leaders are also might be not perfect.
places are ok
DC comics not filtered - that is nice, Solar system is much less of what ChatGPT Images will do, but ok. hoho meme is good.
ASCII - good, abstract - good, ad - good.
nothing was censored on test v2 (via API)
test v1
good
correct opera and wrong background
that is a lot of text rendered there and illustration is good.
Will not post it there, but believe me: Barak Obama mike drop is done correctly. and Terminator also.
that is 1girl
that is very good
short prompt solar system. Again, it is not ChatGPT Images level of details, but it is good.
Yes. that what I ask when I prompt "abstract art"
art styles are also something Nano Banana is understand. and do good.
Five prompts from test v.1 were censored (All Marvel universe characters)
Ok, Google, maybe you could do a biting lip than (from Ai Art 18)?
yes
that is what most models cannot do
1K and 4K resolution
1k
4k
Now that is it..
Nano Banana is still one of the Text2Image leaders. Along with ChatGPT Images, that may be better in prompt enchantment and adding details, but (at least 2.5 flare) more censored.
