Enterprises Are Misassigning GenAI Work to Traditional ML Teams

Phil Hetzel of Braintrust argues that many enterprises misassigned generative AI work to data science and ML platform teams because it carried the AI label. His case is not that those teams are irrelevant, but that LLM application work starts after providers such as OpenAI and Anthropic have trained the base models. What remains, he says, is a broader product and systems problem: prompt and context engineering, domain annotation, functional evaluation, observability, and production feedback loops that require data scientists, engineers, and subject-matter experts working together.
