KV-Latent: Dimensional-level KV Cache Reduction with Frequency-aware Rotary Positional Embedding
By downsampling key and value head dimensions and retraining with distillation, KV-Latent cuts KV cache memory by about 50% on 7-8B LLMs while keeping average benchmark scores within about 1 point of the base model.
