Cost per FLOP continues to drop on an exponential trend (and what bit flops do we mean?). Leaving aside more effective training methodologies and how that muddies everything by allowing superior to GPT4 perf using less training flops, it also means one of the thresholds soon will not make sense.

With the other threshold, it creates a disincentive for models like llama-405B+, in effect enshrining an even wider gap between open and closed.
