GTP 4.5 is not a reasoning model. Reasoning models outperform it clearly. Even OpenAIs o3-mini is smarter while being magnitudes cheaper. Those 2 should be compared in my opinion.
GPT 4.5 feels like a failed experiment to see how far you can push non-thinking models.

ChatGPT is also still hilariously bad at drawing diagrams - universally producing a silly cartoon with misspelled words. The rate of improvement over the past two years is effectively zero.
That's DALL3 which is not an LLM
It's not a failed experiment, it's a very good experiment, because it produced a very useful piece of information for the world (that there's limited return to further size scaling).
