  "account": "Nvidia researchers have developed a technique to transfer the Key-Value (KV) cache from a smaller AI model to a larger one without re-running the entire conversation. This eliminates the need for costly deep learning model training and reduces compute costs and latency in multi-LLM workflows. The linear mapping process is 2.7 to 25 times faster than re-computing the conversation while maintaining up to 98% of the target model's accuracy. The technique works by transforming the KV cache of one model into the expected format of another, enabling seamless handoffs between models in agentic AI systems.",
  "summary": "When an agentic AI system hands a task from a small model to a larger one — or back down again — it pays a steep tax: the receiving model has to recompute the entire conversation from scratch, driving up compute costs and latency. This is a major bottleneck for enterprises building long-horizon, multi-LLM workflows. To solve this challenge, researchers at Nvidia have introduced a cross-model KV…",
