LLM Selection & Evaluation

Data-efficient evaluation and co-optimized recommendation of large language models for practical tasks.

Choosing the right LLM for a task is expensive: full evaluation across benchmarks does not scale. This project develops methods to evaluate models with far less data (via subset selection driven by rank-correlation prediction) and to co-optimize recommendation and evaluation, so that model selection is both cheap and accurate — including for scientific use cases.
