Devs debate the JEV wave: structured outputs aren't new, but decision models are faster and cheaper

- @obie hypes @typesafeai's JEV (decision-model) offering as a genuine phenomenon: a new wave of "normie programmers" plugging fast, cheap intelligence into ordinary codebases
- He predicts all major frontier labs will ship JEV-style offerings within months, and decision models may end up bigger than LLMs long term
- He cites 3+ years of his own work integrating LLMs into production codebases and his book Patterns of Application Development Using AI
- Developer @kieranklaassen pushes back: this isn't new — @jxnlco's instructor library and structured outputs have existed for a while; JEV is essentially the same idea, just faster and cheaper
