On Qwen3-8B, approximately 90% of attention heads exhibit R 0.95, meaning their pre-RoPE Q/K vectors are nearly perfectly concentrated around their respective centers. Critically, these centers are stable across different token positions and across different input sequences — they are an intrinsic property of the model’s learned weights, not a property of any particular input. The research team further confirm that Q/K concentration is domain-agnostic: measuring Mean Resultant Length across Math, Coding, and Chat domains on Qwen3-8B yields nearly identical values of 0.977–0.980.
