> How do you know we aren't already through the exponential part of the S-curve

From a recent METR report, benchmarks point towards an acceleration, LLMs are getting better at a faster rate. There's no sign that we are about to reach the top of the S curve.

> increasingly high costs of training frontier models

Somewhat surprisingly the gains do not seems to come from more compute, we have on the METR report:

> We are confident that the acceleration was not due to an acceleration in the scaling of training compute.
