The models' case: The default for most teams — uncontrolled inputs give strong performance with minimal re-renders, the resolver layer plugs into Zod, Valibot, Yup, ArkType and others so. The models' main caveat: Its own type inference is weaker than fully type-driven rivals — nested/dynamic field paths and generics get awkward, and correctness leans on the. The strongest alternative is TanStack Form — Built from the ground up specifically as TypeScript-first with flawless compile-time type inference for deeply nested paths, zero type drift. Not unanimous: Gemini picks TanStack Form.
