Anthropic Research Confirms Larger Models Become More Incoherent on Complex Tasks

New research from Anthropic validates the "hot mess" theory: scaling up model size doesn't uniformly improve reasoning — on sufficiently complex tasks, bigger models can actually become less coherent.

Research highlighted by @MLStreetTalk shows that Anthropic has found larger models exhibit increased incoherence on complex tasks. The finding is counterintuitive to the prevailing "scale is all you need" narrative and validates what some researchers have been calling the "hot mess" theory — the idea that larger parameter counts can produce more confident but less logically consistent outputs when task complexity exceeds certain thresholds.
