eliebakouch: verifying LLM training science is a compute function — and RSI is hard to doubt

LLM researcher eliebakouch argues that verifying the science of LLM training is a function of compute: as compute scales, you can almost infinitely parallelize and compress time. Math is even easier (inference-only, highly parallelizable, proofs rarely interact negatively); model training needs 2x compute but the dynamics are the same. Labs already measure pre-training gains via a scaling ladder — how much a proposal saves at fixed budget (FLOPs, time, KV cache, data efficiency) to hit the same metric. Post-training is similar modulo reward hacking; alignment is less certain, since measuring behavior without eval awareness is hard. Put together, "hard to not believe in RSI."
