Latency Patterns for Faster AI Apps: Beyond Model Inference
bibryam · x · 2026-08-30
The article argues that model inference is just one part of the latency equation. The true user experience depends on the "critical path"—the time from user action to the first useful result.
AI-Specific Critical Path Components:
- Context retrieval
- Model gateways
- Multiple LLM calls
- Tool usage
- MCP servers
- Agent coordination
- Verification steps
Key Takeaways:
- Users experience the full path, not individual components.
- A fast database query or model call doesn't guarantee a fast app.
- Model-serving optimizations matter but address only a local part.
The article aims to provide general latency patterns applicable to both AI and non-AI applications.
