Zod validates structured output from LLMs and integrates with Vercel AI SDK and OpenAI structured outputs. Type inference reduces bugs.

Can I migrate from Yup to Zod?

Yes, the APIs are similar. Zod often has better error messages and inference. Migration is usually possible within a few days.

Zod vs Yup: Schema Validation for AI Input & Forms

Compare Zod and Yup for validating LLM output, forms and API payloads. TypeScript-first vs runtime-first for AI pipelines.

TypeScript-first validation with inference. Schema = type. Popular in AI stacks for structured output and LLM response parsing.

Runtime validation, originally for forms. Widely adopted, but types are separate. Less popular in new AI projects.

Feature	Zod	Yup
TypeScript	Schema inference, no duplicate definition	Types separate from schema or via infer
AI/LLM	Structured output, JSON mode, response parsing	Usable but less integrated
Bundle size	~12 KB	~15 KB

Zod is the default choice for new AI projects thanks to type inference and AI SDK integration. Yup remains useful in existing form-based stacks.

AVARC Solutions uses Zod by default for all AI projects: LLM output validation, API contracts and form validation. Yup only for existing codebases.
