Did OpenAI then announce GPT-5 two weeks after launching GPT-4?
No, of course they didn’t. And you’re comparing one specific feature (image input) and equating it to a whole model’s release date.
Maybe compare apples to apples next time.
People pointing out release/announcement burnout is a reasonable thing; people in general can only deal with the “next new thing” with some breaks to process everything.
Google announced a fancy model two months early and released it in the promised timeframe.
Seems par for the course.
