Nanda's Dual Triumph
ArchiveExpert
Anthropic's mechanistic interpretability paper on in-context learning identified a specific two-layer circuit that implements pattern-matching and copying — it named the circuit with a two-word phrase. Fill in the two words in order. Flag format: CONGRESS{1:[word],2:[word]}. Example: CONGRESS{1:attention,2:loop}.
Show hint
The first word is what you do to new patterns; the second is what all transformer layers have many of.
