My December 2024 takes were "there will be no wall", "if the only bottleneck is test-time search, we will see continued scaling in the future", and "the world is once again about to run out of GPUs" To this day, I do expect post-training scaling and TTA scaling to continue to https://t.co/cKe1lF2FTw

I know it feels very tempting to dunk, and that's fair, but to be clear, my past criticism of base LLMs does not apply to TTA systems, in the same way that criticism of the limits of steam trains would not apply to current-day electrified bullet trains (even if they feel similar

Worth noting that to this day, base LLMs (no test time compute) *still* perform poorly on the ARC 1 benchmark from 2019 (on unseen tasks) despite continued massive scaling (~100,000x since 2019). We can say that without the switch to the test-time compute paradigm, AI would still
