Developer predicts Jev-style decision models will outgrow LLMs

A developer who has spent three years putting LLMs into production says Jev lets ordinary programmers plug in fast, cheap intelligence and predicts decision models may eventually be bigger than LLMs.

Mark my words: @typesafeai JEV is not only the new hottness, it's a genuine phenomenon as a whole new wave of normie programmers learn how to plug fast, cheap intelligence into their otherwise normal codebases. Feels like Xmas 2025 all over again. I predict that all the major frontier labs will have JEV-style offerings within the next few months. I will not be surprised one bit if decision models end up being bigger than LLMs in the long run. If you think I'm being hyperbolic, consider that hacking LLMs into production codebases has literally been my focus for over 3 years now and I wrote the definitive book on the subject: Patterns of Application Development Using AI We are definitely in a singularity, because nobody I know saw this coming.
