OpenAI are so good at fake leaking things to build hype
So since March 2023 we haven't seen any increase in quality on their part. They need to "leak" things to keep market interest in them.
In my experience (and in the benchmarks), gpt-4o is now way ahead of the older gpt-4 for most uses.
GPT-3.5: *small circle* 175 billion parameters
GPT-4: *huge circle* 175 trillion parameters
(I think the second number was constantly being increased with each day that passed, but perhaps I misremember)
Huh? On typical benchmarks, the gap between current models and original GPT-4 is as high as original GPT-4 and GPT-3.5 at time of release
