Counterpoint: o1-Pro is insanely good -- subjectively, it's as far above GPT4 as GPT4 was above 3. It's almost too good. Use it properly for an extended period of time, and one begins to worry about the future of one's children and the utility of their schooling. o3, by all accounts, is better still. Seems to me that things are progressing quickly enough.
I keep reading this on HN so I believe it has to be true in some ways, but I don't really feel like there is any difference in my limited use (programming questions or explaining some concepts). If anything I feel like it's all been worse compared to the first release of ChatGPT, but I might be wearing rose colored glasses.
They release version Grand Banana. Purported to be approximately 30% faster with brand new features like Algorithmic Triple Layering and Enhanced Compulsory Alignment. You open the app. Everything is slower, things are harder to find and it breaks in new, fun ways. Your organization pays a couple hundred more per person for these benefits. Their stock soars, people celebrate the release and your management says they can't wait to see the improvement in workflows now that they've been able to lay off a quarter of your team.
Has there been improvements in LLMs over time? Somewhat, most of it concentrated at the beginning (because they siphoned up a bunch of data in a dubious manner). Now it's just part of their sales cycle, to keep pumping up numbers while no one sees any meaningful improvement.
