Ep 97: Jev Creator on Decision Models, Benchmark Fatigue & Why the Labs Missed It
Show notes
Jev creator and TypeSafe AI co-founder, Diogo Almeida, joins Jacob Effron to talk about why AI still isn't automating the easy work it's been smart enough to do for years, and why he built a new class of model around reliability.
Diogo coauthored OpenAI's InstructGPT paper and spent two years in stealth building Jev, a "system one" model that returns structured decisions instead of text, which launched in September.
Diogo and Jacob discuss what the viral launch was really like, why he thought Jev would take a week and it took years, why almost every LLM call should be meant for a machine, and why developers should push model providers harder on jaggedness. They also cover the tyranny of the KV cache in coding agents, why new model shapes are cheap and reliability is the hard part, his estimate that coding agents deliver a 20 to 40% speedup, why he sees financial engineering as the labs' underrated strength, and why he thinks we're two gigantic breakthroughs from true AI agency.
