Understand and Improve Agent Latency
Blog post from LiveKit
Improving the latency of voice agents is a complex task with no straightforward answers, as it involves various factors such as network latency, model selection, and geographic location, each contributing differently to overall latency. The key to latency improvement lies in monitoring performance using tools like Agent Observability to identify bottlenecks, hosting agents and models in the same region to reduce network delays, and evaluating faster models while maintaining a balance between latency and capability. Architectural choices, such as opting for a pipeline or realtime model and considering geographical proximity, also play significant roles in latency reduction. Implementing practices like preemptive generation, optimizing model-specific settings, and consolidating external API calls can further enhance performance. While latency improvements often involve trade-offs with features like reasoning or accuracy, focusing on the most impactful sources of latency and continuously re-evaluating model choices can help maintain competitiveness without compromising user experience.
