Ed Grefenstette, Head of Machine Learning at Cohere, recently spoke to AIM about his shift from big tech to startup. Cohere’s Command Beta model gained the top spot in the Stanford HELM (Holistic Evaluation of Language Models) earlier this month, beating out 36 other LLM models. Grefenstette remained modest about the achievement, noting that leaderboards should be taken with a grain of salt. He is more excited about the week-on-week progress of their models than the leading position. Grefenstette’s interest in AI began during his undergraduate studies in philosophy of mind and reading science fiction and cyberpunk novels. He then pursued computer science due to lack of job opportunities in philosophy.
