Large Language Models

Large Language Models (LLMs) power everything from chatbots to code generators, but their true value in production environments hinges on rigorous evaluation using detailed metrics. This guide breaks down key metrics, benchmarks, and best practices for assessing LLM performance, drawing from industry-leading research and tools to help you deploy reliable AI systems.[1][2] Why LLM Evaluation Matters in Production In production, LLMs face real-world challenges like diverse inputs, latency constraints, and ethical risks. Traditional metrics like perplexity fall short; instead, use a multi-faceted approach combining automated scores, human judgments, and domain-specific benchmarks to measure accuracy, reliability, and efficiency.[1][4] ...
