Defined in: packages/ai/src/types.ts:128

Union type for schema input - can be any Standard Schema compliant validator, any Standard JSON Schema compliant schema, or a plain JSONSchema object.

Standard JSON Schema compliant libraries (carry the JSON-schema converter):

• Zod v4.2+ (natively supports StandardJSONSchemaV1)
• ArkType v2.1.28+ (natively supports StandardJSONSchemaV1)
• Valibot v1.2+ (via toStandardJsonSchema() from @valibot/to-json-schema)

StandardSchemaV1 covers libraries whose published types only expose the validator surface — Zod's core $ZodType['~standard'] is currently typed as StandardSchemaV1.Props even though the runtime attaches the jsonSchema converter, so this branch is what makes InferSchemaType recover the inferred type for callers using z.ZodType<T>.
