Evaluation is the single biggest bottleneck holding back enterprise AI adoption
“So, so I do think that evaluation is the biggest bottleneck for AI adoptions, because unless, like, if we can, like, if we can, like, develop a more reliable way to evaluate the application, that application is not going to get adopted. Like, or maybe, maybe i…”

Chip Huyen warns million-token context capacity does not imply efficient processing
“Just because a model, I think the second reason may be actually more important at least for now is that just because a model can fit in a million con token context doesn't mean that it can process that million token efficiently.”

Chip Huyen argues human-generated plans are poor training data for AI agents
“When we ask humans to generate like what they consider the best plan for an actions, for a task, it's actually like not quite the best plan for AI, because what is what is easy or efficient for humans is not the same as easy and efficient for AI, right?”
