5x Faster Time to First Token with NVIDIA TensorRT-LLM KV Cache Early Reuse
In our previous blog post, we demonstrated how reusing the key-value (KV) cache by offloading it to CPU memory can accelerate time to first token (TTFT) by up to 14x on x86-based NVIDIA H100 Tensor Core GPUs and 28x on the NVIDIA GH200 Superchip. In this post, we shed light on KV cache reuse techniques and best practices that can drive even further TTFT speedups. Introduction to KV cache LLM models are rapidly being adopted for many tasks, including question-answering, and code generation. To generate a response, these models begin by converting the user’s prompt into tokens, which are then … Read more
