Researchers investigated the impact of removing a single attention head from a 128-head chess transformer model. They found that ablating just one head caused the model to fail at identifying a specific chess tactic, Paul Morphy's queen sacrifice. This suggests that even a small component within a large transformer model can play a critical role in its performance on complex tasks. AI
