I was going to nitpick the missing apostrophe in movie posters caption ("STARFALLS REVENGE") but its missing from the prompt, too.

The way it totally disregards the many explicit instructions given in the "four panel" comic strip.

> Imagen 4 Ultra: When your creative vision demands the highest level of detail and strict adherence to your prompts, Imagen 4 Ultra delivers highly-aligned results.

It seems that you may need the "Ultra" version if you want strict prompt adherence.

It's an interesting strategy. Personally, I notice that most of the times I actually don't need strict prompt adherence for image generation. If it looks nice, I'll accept it. If it doesn't, I'll click generate again. For creativity task, following the prompt too strictly might not be the outcome the users want.

Same for the poster. Asks for the ship to be going towards the right, and it's clearly doing the opposite

As seen from the AI's perspective.

To the left of the "detailed spaceship" I think I see a distortion pattern reminiscent of a cloaked Klingon bird of prey moving to the right. Or I'm just hallucinating patterns in nebular noise.

Though that was only Imagen 4 Fast, not Imagen 4 or Imagen 4 Ultra.

I guess it's kinda nicely genuine that the "four panel comic strip" has some errors in it (misunderstanding caption + cat high-fiving itself in the bonus fifth panel)

I was just thinking that. It has many, many errors.

1. Not seen browsing ”ai.dev”.

2. The text ”Imagen 4 is now generally available!” is spoken, not a comic caption.

3. Invalid second panel.

4. Hallucinates ”Meet Imagen 4 fast!”

5. Hallucinates ”It offers low..” etc. (this is the second part of a single sentence said by the cat)

6. Hallucinates ”You can export images in 2K!” (this sentence is not asked for)

7. Doesn’t have the cat and the dog in the fourth panel.

Here’s the gpt-image-1 counterpart with the issues I could find:

1. The text ”Imagen 4 is now generally available!” is still spoken, not a caption.

2. ”low latency” -> ”low-laten”

(3. Has that ugly gpt-image-1 trademark yellow filter requiring work in post to avoid.)

I didn’t bring up the ”retro comic look” thing. I certainly think it’s an issue with Imagen 4’s version. It doesn’t look very old school at all. But I can’t judge the OpenAI one either on that, I’m no comic book expert, so I just skipped that one.

Looks so much better than the yellow tinted chatgpt output in my eyes

Clicking on "Read the documentation" leads to a page that documents nothing about the latest Imagen models and only provides examples using Gemini 2.0 Flash.

I am currently building an AI product which relies on Imagen 3 to generate a lot of photorealistic, cinematic or HDR images. I tried Imagen 4 during preview, but results were too "cartoonish". Did anyone else have the same experience?
LeoPanthera · 8m ago
Yes, it seems very reluctant to generate anything that could be mistaken for a photo.

Wasn't Imagen 4 released months ago?
nevir · 47m ago
Yes, but usage was very limited / restricted. Now it's widely available

I hate that they always announce their image models months before they make them available. They should just announce them later. OpenAI does this much better, with a few days delay at most.

The webcomics is awful. It feels off, the characters look very fake, unsettling in the way they communicate. The prompt is shown bellow the image, but for me the result looks closer to a prompt "Create lifeless characters reciting marketing slop. They must fake an over exaggerated excitement but it should be clear they don't believe in what they're saying and have no souls".

Also, the prompt specifically ask "Panel 4 should show the cat and dog high-fiving" but the cat is high-fiving ... the cat. Personally I find this hallucinated plot twist good, it makes the ending a bit better. Although technically this is demonstrating a failure of the tool to follow the instructions from the prompt. Interesting choice of example for an official announcement.
