Stanford CS336 Language Modeling from Scratch Lecture 12 Evaluation Overview

Evaluating language models may seem as simple as measuring a specific model's performance, but it is actually fraught with challenges. The industry currently evaluates models through various metrics, such as benchmark scores like MMLU, cost-effectiveness indicators combining model accuracy and per-token cost, OpenRouter platform data based on user traffic routing, and Chatbot Arena which relies on human pairwise preference comparisons. However, an evaluation crisis currently exists, as some benchmarks may have reached saturation or been gamed, making it difficult to determine the most accurate evaluation method amidst a plethora of models and benchmark data.

Key Takeaways:

The fundamental purpose of evaluation depends on specific needs, and there is no single true evaluat...
