Researcher

David Heineman

David Heineman is a language-model researcher whose work spans text-generation evaluation, decoding, and open models. At Georgia Tech, he coauthored LENS and SALSA for text simplification and helped build Thresh for fine-grained text evaluation. His later work included multi-prompt decoding, studies of benchmark reliability, and Ai2's OLMo 3 report. He also worked on language-model pretraining with Meta Superintelligence Labs (FAIR). As of October 2026, he is a first-year PhD student at Stanford, focused on pretraining, data, and language-model evaluation.
