LLM Latency Benchmark Guide for Production Model Selection (2026)
Production LLM selection balances latency and accuracy. This guide explains latency benchmarks, throughput limits, and selection criteria for real-time applications.
Implementation Steps
- Benchmark latency by model: measure time-to-first-token and total response time.
- Compare throughput limits: requests per second, concurrent request handling.
- Evaluate latency-accuracy tradeoff: faster models may sacrifice quality.
- Match model to use case: real-time chat vs batch processing requirements.
- Monitor production latency: track latency degradation and alert thresholds.
