How Agents Decide: Goodfire's Eric Bigelow on Critical Tokens, Phase Shifts, & In-Context Learning

What was said

"I usually I I tend towards like the scale of 7 to8 billion or more being a sweet spot where like you can start to do good interpretability research."

Eric Bigelow argues he often chooses models around 7–8 billion parameters for interpretability experiments. He says they are large enough to show interesting zero-shot behaviours while still being tractable to study.
