I follow things pretty closely, and I was genuinely unsure if GPT5-pro was a real thing or just equivalent to setting GPT-5 to high reasoning.
Does the fact it's entering the API confirm that it's a fully separate thing which is not widely benchmarked, and which was not part of the GPT-5 stream?
This particular thing has not been well communicated AFAICT.
GPT-5 Pro is different from GPT-5 just like o3 Pro is different from o3 and o1 Pro is different from o1 :) OpenAI doesn't want to tell the truth, but it might be something similar in the spirit to e.g. Entropix. [0]
