TypeSafe’s Jev aims to make AI decisions reliable enough for software

Diogo Almeida says Jev returns probabilities that developers can test and use to set their own thresholds, instead of generating a polished answer that may hide a bad decision. He wants developers to combine small, dependable decisions into larger automated workflows. His test for current models: “95% Einstein, 5% Mr. Bean. And if it doesn’t tell you when it’s the Mr. Bean, then how are you gonna automate anything?”

Aaron Levie predicts background agents could drive 100 to 1,000 times more tokens

Levie argues that letting many agents work in parallel on reviews, audits and other information tasks could use 100 to 1,000 times more tokens than today’s back-and-forth chats. He also sees Meta’s Muse open weights model helping enterprises pair frontier models with cheaper, tailored models for repeatable workflows.
