Story

Multi-turn serving hurts because the KV cache grows linearly with conversation length, choking GPU memory and bandwidth. Tangram spends memory unevenly across the cache instead of treating all tokens equally, cutting the footprint of long sessions. Source: arXiv Directly useful if you self-host a model behind a chat or agent loop and your sessions run long.
