Modal launches Sticky Sessions for stateful serverless applications

Modal has introduced a new feature called Sticky Sessions, designed to enhance its serverless compute capabilities for stateful applications. This feature ensures that all requests within a single user session are routed to the same container, a crucial requirement for applications like speech-to-text models, conversational agents, and multiplayer games. Sticky Sessions build upon Modal's existing low-latency Modal Servers infrastructure, which includes an in-house stateless proxy for efficient routing and load balancing. The new functionality addresses the need for fixed routing, session lifecycle management, and session-based autoscaling, moving beyond the previous request-level routing that offered only best-effort affinity.

IMPACT Enhances serverless capabilities for stateful AI applications like real-time inference and conversational agents.
