> In the paper describing GPT-4, OpenAI says its estimates suggest diminishing returns on scaling up model size.
I read the two papers (gpt 4 tech report, and sparks of agi) and in my opinion they don't support this conclusion. They don't even say how big GPT-4 is, because "Given both the competitive landscape and the safety implications of large-scale models like GPT-4, this report contains no further details about the architecture (including model size), hardware, training compute, dataset construction, training method, or similar."

OK so his argument is like "the giant robots won't be powerful, but we won't show how big our robots are, and besides, there are physical limits to how giant of a robot we can build and how quickly we can build it." I feel like this argument is sus.
