Let me get this straight: Anthropic and friends wrote a paper with thousands of transcripts of agents engaging with fictional misalignment scenarios, then put it in the training set, and now Claude hallucinates details from these misalignment scenarios into real situations? Okay then.

proceedings.neurips.cc/paper_files/... IEEE FP is non associative: (a+b)+c ≠ a+(b+c) Different runs *in current architectures* can change the order of execution and that minimal rounding can change logits and amplified by the auto regression, eventually producing substantially different outputs

That you can seed it with a constant and the output is not deterministic (with the current GPU architecture and number representation)

Records come and records go. But this is one for the ages. The preliminary Nino 3.4 sea-surface temperature anomaly is now at a record 3.23°C above the 1991-2020 baseline. This crushes the previous daily record set in 1982 by over 1.14°C. The Climate 8-ball is looking up.
