Because OpenAI needs a steady influx of money, big money. In order to do so, they have to convince the people who are giving them money that they are the best. An objective way to achieve this is by benchmarking. But once you enter this game, you start optimizing for benchmarks.
At the same time, in the real world, Anthropic is following them in huge leaps and for many users Claude 3.5 is already the default tool for daily work.
From a user perspective too, I was a subscriber from the first day of gpt4 until about a month ago. I thought about subscribing for the month to check this out but I am tired of the OpenAI experience.
Where is Sora? Where is the version of chatgpt that responds in real time to your voice? Remember the gpt4 demo that you would draw a website on a napkin?
How about Q* lol. Strawberry/Q*/o1, "it is super dangerous, be very careful!"
Quietly, Anthropic has just kicked their ass without all the hype and I am about to go work in sonnet instead even bothering to check o1 out.
