Modal cuts serverless function latency with new distributed I/O plane

Modal has upgraded its serverless functions' I/O plane to reduce network latency. The new system routes function inputs and outputs through geographically distributed regions, rather than a single central server. This change has resulted in an approximate 80ms reduction in p50 latency for function calls, benefiting applications like retrieval-augmented generation that require low latency. AI

IMPACT Reduces latency for AI applications like RAG, potentially improving user experience and operational efficiency.
