Latency Optimization for AI Apps
Latency shapes how intelligent a product feels. Even strong answers can feel weak if they arrive too slowly, especially in chat, search, and copilots where users expect immediate feedback.
Major Sources of Delay
- Slow model inference
- Large prompts and long outputs
- Retrieval pipelines with multiple network hops
- Tool calls that wait on external systems
Ways to Reduce Latency
- Stream responses as tokens arrive
- Cache repeated work
- Route simple tasks to faster models
- Run retrieval and preprocessing in parallel where possible
- Trim unnecessary context before generation
Product Perspective
Latency is not just a systems metric. It changes user behavior. Faster feedback encourages exploration, while slow answers make even good AI features feel unreliable.
