Those simple prompts produce nearly the exact same layout in the 2 different models?

My harness expands the prompt into a json representation that specifies layout much more rigorously, which is why you see such that amount of alignment between the two.

That internal json backing helps significantly when you want to maintain consistent design system components/patterns across multiple pages. The aligned layout is it working as intended.

Totally normal for modern models due to training on the same datasets supplied by third parties, dataset contamination, and mode collapse, especially for simple prompts that don't have enough semantic capacity. -isms are often very similar even without distillation, and tend to come and go in waves along with model generations.

Equally confused with this. They must be using a lot more guidance than just the provided prompt.

Qwen is trained off of gpt’s outputs. This is both a positive and negative

Qwen's latest image models have a ton of distillation from gpt-image, same with Grok Imagine.

Even the artifacts are getting picked up.
