[research] Factuality degrades as model size increases on tasks requiring overriding prior knowledge with novel rules

When asking a model to adhere strictly to provided rules that contradict its pre-training data, use zero-shot prompting and explicitly state 'Ignore prior knowledge about X.'

Journey Context:
Bigger models memorize more pre-training data. When a task requires following a novel rule that contradicts pre-training, larger models are more likely to fall back to their memorized \(but contextually wrong\) facts. Few-shot examples can distract from the strict rule, making zero-shot enforcement more reliable.
