It doesn't matter where we draw the line, or what someone else said at some point. I merely pointed out your argument wasn't a sound rebuttal. Criticizing subjective experiences to assess the situation is, but that cuts both ways.

> HN commenters have been saying that LLMs plateaued ever since the first ChatGPT release.

Your earliest example was 2 years after release, when LLMs were already widely used and there is literally a source to support the claim. Now, you need to show research efforts, time and resource investments, ... are producing proportional results, disproving diminishing returns. If there are diminishing returns, LLMs are plateauing.

Also, manual capability extensions, or use/edge case adaptations, which may improve subjective usability are not exactly advances in AI as technology. LLMs still hallucinate. LLms still fundamentally struggle with certain classes of problems (e.g. counting), but you increasingly need to come up with different problem dress-ups because of targeted interventions to manufacture hype and a limited supply of test cases. Can you make the case AI got actually more intelligent, fundamentally? That is, not an increase in case specific usability, but a decrease in fundamental limitations. And is this proportional to improvement efforts?
