I have a certain use case for such image generators. Feed them an entire news article I fetch from bbc and ask it to create an image to accompany the article. Thus far only midjourney managed to understand context. And now this, which is even more impressive. We live in interesting times.
1. Reduce article to a synopsis using an LLM
2. Generate 4-5 varying description prompts from the synopsis
3. Feed the prompts to an imagegen model
Though I'd wager that gpt-image-1 (in the ChatGPT) being multimodal could probably managed it as well.
