On November 6, 2026, TypeSafe AI stated in a tweet that reliable decisions cannot depend on decision models. It said that hiding semantic logic in string prompts, embedding vectors, or complex machine learning is useless, because data distributions are always smarter than people. TypeSafe AI argued that one should clearly define what needs to be known, confirm that reading the data directly is sufficient, and then combine reliable judgments with code, and stated that Jev can make reliable judgments. On the same day, in response to "why not call Jev a decision model," TypeSafe AI added that when faced with complex data, the model itself cannot guarantee reliable decisions; reliability requires code, and reliable decisions come from combining reliable judgments in code. Currently, this view has been published by TypeSafe AI in a first-party capacity, and there is no follow-up development from other independent sources.

TypeSafe AI: Data Distributions Are More Absurd Than Your Tricks
TypeSafe AI argues that hiding semantic logic inside string prompts, embedding vectors, or complex ML is useless—data distributions are always much smarter than people. The author suggests: clearly define what you need to know, and confirm that reading the data directly is enough to know it, so you can make reliable decisions.

TypeSafe AI: Reliable decisions rely on code, not decision models
TypeSafe AI stated in a tweet that reliable decisions cannot depend on decision models: hiding semantic logic in string prompts, embedding vectors, or complex ML is useless—data distributions are always smarter than people. Its argument is to clearly identify what needs to be known and confirm that reading the data directly is sufficient, then use code to compose reliable judgments, and it claims that Jev can make reliable judgments.

TypeSafe AI: Reliable decisions rely on code, not decision models
TypeSafe AI responds to "why not call Jev a decision model": when faced with complex data, the model itself cannot guarantee reliable decisions; reliability requires code, and reliable decisions come from composing reliable judgments in code. It adds that you can hide semantic logic in string additional conditions, embedding vectors, and various ML, but data distributions are always stranger than you can imagine, so you must be clear about what you need to know and confirm that reading the data directly is sufficient.
