Pros & cons

Pros

Aggressive KV pruning for long context with retention of high-importance tokens.

Cons

Research-stage; pruning quality bounded by importance heuristic.

Claims & capabilities

Training-free KV cache compression that preserves all token information using head-specialized strategies — full caches for retrieval heads, discarding remote tokens in non-retrieval heads, with compensation tokens; over 70% reduction in KV cache size; 3X reduction under general cases; no noticeable performance impact; FlashAttention-compatible
