Oh I very much agree that it's great to see more research and findings and improvements in this field. I'm just a little puzzled by GP's tone (which suggested that it isn't completely expected to find new things about LLMs, a few years in).
Sorry lol, to me it felt like you were (pleasantly) surprised by this research. IMO I'd hardly be surprised to see breakthroughs in LLM understanding years or even decades from now. I guess I misunderstood your tone.
