Dan Klein, co-founder & CTO of Scaled Cognition and ACM Grace Murray Hopper Award winner, breaks down why LLMs are fundamentally plausibility engines and how his team built APT1 for under 11 million dollars. He explains why multi-model checking fails, why benchmarks measure the wrong thing, and what it takes to ship AI that enterprises can actually trust.
