Amazon SageMaker Inference introduces prefix-aware routing for improved LLM performance.

“In our benchmarks on Llama 3.1 70B, this reduced P50 TTFT by up to 77 percent.”

Amazon SageMaker Inference has launched a new feature called prefix-aware routing, which optimizes request handling for large language models. This new routing strategy significantly reduces time-to-first-token and improves cache hit rates, enhancing overall performance in LLM applications.
