LLM evaluation rankings shift with token budget, study finds

A new research paper from arXiv explores how the evaluation of large language models can be significantly affected by the token generation budget. The study found that in 3-19% of cases, model accuracy decreased as the budget increased, and these effects were specific to each model. Model rankings reversed across different budgets on all tested benchmarks, indicating that standard evaluations may not accurately reflect true performance. The research also highlighted potential complementarity between models, suggesting that a budget-aware routing system could capture a portion of this performance gap. AI

IMPACT Highlights the need for more nuanced LLM evaluation protocols that account for varying computational budgets.
