Zod 4.5: z.compile() precompilation speeds parse up to 9x, slashes memory
Zod 4.5 introduces z.compile(), an AOT schema compiler that speeds up parsing of objects, arrays, and unions by ~3–9x. Combined with z.validate()—a fast boolean check that skips ZodError construction—invalid inputs are up to 16x cheaper to reject than safeParse. Benchmarks show 47.5M ops/s on the Moltar parseSafe fixture, ahead of typia's 45.3M. A move of bound methods to prototypes cuts per-schema heap retention by up to 9.8x. The release also includes breaking changes: string length now counts Unicode code points, z.iso.datetime() requires seconds, record keys and intersections match TypeScript semantics, and __proto__ is always stripped. Useful for TS teams doing heavy runtime validation in services, forms, and data pipelines.
Zod 4.5 is now available.
At a glance:
z.compile() — the flagship feature of Zod 4.5
z.creditCard() — 12–19 digits plus Luhn checksum
z.properties() — the multi-property counterpart to z.property()
z.deepPartial()/.exactPartial()
z.validate(): boolean — a fast-path to verify input validity without a full parse (up to 16x faster on invalid data)
9x reduction in memory footprint

You can now pre-compile any Zod schema using z.compile(schema). This dramatically speeds up parsing performance.
A compiled schema can be used exactly like an uncompiled one. There are no special rules around compiled schemas. They're just faster.
On objects, arrays, and unions, this speeds up parsing by a factor of ~3–9. More complex schemas stand to benefit more than simpler ones.
Time per parse by schema type, standard parser vs compiled — lower is better (benchmark)
现在可以用 z.compile(schema) 预编译任意 Zod schema，解析性能会大幅提升。
编译后的 schema 用法与未编译的完全相同，没有任何特殊规则——只是更快。
在对象、数组和联合类型上，解析速度约提升 3–9 倍；schema 越复杂，收益越明显。
按 schema 类型比较单次解析耗时，标准解析器对比编译后的版本——越低越好（基准）
Below are the Moltar benchmark results comparing Zod (compiled and uncompiled) against the Moltar ParseSafe bench.
Throughput on the moltar benchmark fixture (parseSafe: returns a new object with unknown keys stripped) — higher is better (benchmark)
And the equivalent results for the Moltar AssertLoose bench. Tested against the new z.validate(schema, input) function (detailed later in the post).
Throughput on the moltar benchmark fixture (assertLoose: returns a boolean, unknown keys allowed) — higher is better (benchmark)
下面是用 Moltar 基准做的对比，Zod（编译版与未编译版）对 Moltar ParseSafe 基准。
Moltar 基准上的吞吐量（parseSafe：返回剔除未知键后的新对象）——越高越好（基准）
下面是 Moltar AssertLoose 基准的对应结果，测试对象是文中稍后详细介绍的新 z.validate(schema, input) 函数。
Moltar 基准上的吞吐量（assertLoose：返回布尔值，允许未知键）——越高越好（基准）
Zod's entire test suite runs twice—once normally and again with auto-compilation enabled globally—to ensure perfect fidelity.
import "zod/compile"
To compile every schema in an application, import zod/compile once at the top of your entry point. Every schema constructed after that import is automatically compiled the first time it's used to parse data.
It also works as a Node.js CLI flag, which guarantees it runs before any module defines a schema:
Or set preload in bunfig.toml or nub.jsonc.
nub.jsonc
Zod 的完整测试套件会跑两遍：一遍常规运行，一遍全局开启自动编译，以确保两者行为完全一致。
import "zod/compile"
如果希望应用里每个 schema 都编译，只需在入口文件顶部引入一次 zod/compile。此后构造的每个 schema 都会在首次用于解析数据时自动编译。
该功能也支持 Node.js CLI 标志，可保证在任何模块定义 schema 之前生效：
或者也可以在 bunfig.toml 或 nub.jsonc 中设置 preload。
nub.jsonc
A new string format: 12–19 digits, optionally separated by single spaces or hyphens, with a valid Luhn checksum. (#5931)
新增字符串格式：12–19 位数字，可选用单个空格或连字符分隔，并要求通过 Luhn 校验和。(#5931)
The multi-property counterpart to z.property(). (#5912)
这是 z.property() 的多属性版本。(#5912)
Back in functional form after being removed as a method in Zod 4. (#5928)
The result is still a ZodObject, so .shape and .extend() keep working.
Like .partial(), but wraps each field in z.exactOptional() instead of z.optional(): keys may be omitted, but an explicit undefined is rejected. This matches TypeScript's Partial<> under exactOptionalPropertyTypes. (#6065)
In Zod Mini it's a top-level function: z.exactPartial(Recipe).
在 Zod 4 中作为方法被移除后，如今以函数形式回归。(#5928)
结果仍是 ZodObject，所以 .shape 和 .extend() 继续可用。
与 .partial() 类似，但每个字段用 z.exactOptional() 而不是 z.optional() 包裹：键可以省略，但显式传入 undefined 会被拒绝。这与开启 exactOptionalPropertyTypes 时 TypeScript 的 Partial<> 行为一致。(#6065)
在 Zod Mini 中它是顶层函数：z.exactPartial(Recipe)。
Standalone boolean validation, in Zod, Zod Mini, and Zod Core. It answers "is this input valid?" without constructing a ZodError, which makes rejection cheap: on invalid input it is up to 16x faster than .safeParse().success. The return type is a guard on the schema's input type, and z.validateAsync() covers schemas with async refinements. (#6471)
独立布尔校验，在 Zod、Zod Mini 与 Zod Core 中均可用。它回答“这个输入是否合法”，不会构造 ZodError，因此拒绝成本很低：对无效输入，比 .safeParse().success 快最多 16 倍。返回类型是该 schema 输入类型的类型守卫；z.validateAsync() 则覆盖带异步 refine 的 schema。(#6471)
Project a schema onto its input or output side. Useful for validating the two halves of a codec independently. (#5928)
This is a no-op on schemas not containing codecs/pipes.
将 schema 投影到输入侧或输出侧，适合独立校验编解码器两端的值。(#5928)
对于不包含 codec/pipe 的 schema，这是一个空操作。
A utility to define a Zod schema that agrees exactly with a static type, often one that is handwritten or externally defined. (#5913)
这个工具用来定义与某个静态类型完全一致的 Zod schema，常用于手写或外部定义的类型。(#5913)
Extract a discriminated union member by discriminator value. (#5947)
按判别值从可判别联合中提取对应成员。(#5947)
Zod recursive schemas now support cyclical data. For bundle size reasons, Zod Mini requires you to register a memoizer explicitly. (#6387, #6482)
Zod 的递归 schema 现在支持环形数据。出于包体积考虑，Zod Mini 需要你显式注册一个 memoizer。(#6387, #6482)
In Zod 4.4 a bare z.string() retained 7.5kb of heap. In Zod 4.5 it retains 784 bytes.
Retained heap per schema instance, Zod 4.4.3 vs 4.5 (benchmark)
In Zod 4.4 and earlier, all schema methods were automatically bound to the instance itself. This allowed users to pluck methods from schemas without causing issues due to this-binding.
A consequence of this is that each bound method allocates space on the heap; method implementations are not shared across all instances via prototype, as you'd expect. Zod 4.5 implements a method memoization pattern that avoids allocating bound methods until they are actually accessed.
Zod 4.4 中一个裸 z.string() 会保留 7.5kb 堆内存；Zod 4.5 中只保留 784 字节。
各 schema 实例保留的堆内存对比，Zod 4.4.3 vs 4.5（基准）
在 Zod 4.4 及更早版本中，所有 schema 方法都会自动绑定到实例自身。这让用户可以把方法从 schema 上取出来用，而不用担心 this 绑定问题。
代价是每个绑定方法都会在堆上占用空间；方法实现不会像预期的那样通过 prototype 在所有实例间共享。Zod 4.5 采用了方法记忆化（memoization）模式，只在方法真正被访问时才分配绑定方法。
Zod .parse()/.safeParse() instantiates a JavaScript Error, which captures a stack trace. In the case of validation failures, this is often much slower than the parsing logic itself. When using .safeParse(), Zod no longer captures this stack trace, speeding up failure-path parses by a factor of ~7.5x. (#6316, #6450)
Player schema (benchmark)
Zod 的 .parse()/.safeParse() 会实例化一个 JavaScript Error 来捕获堆栈。校验失败时，这通常比解析逻辑本身慢得多。现在使用 .safeParse() 时 Zod 不再捕获这个堆栈，失败路径的解析速度提升约 7.5 倍。(#6316, #6450)
Player schema（基准）
A shape can now declare a symbol key. TypeScript tracks it: a const symbol infers as unique symbol, so z.infer makes the key required and checks its value type. Undeclared symbol keys are still ignored. (#6448)
shape 现在可以声明 symbol 键。TypeScript 会对其跟踪：const symbol 推断为 unique symbol，因此 z.infer 会把这个键设为必填，并检查其值类型。未声明的 symbol 键仍会被忽略。(#6448)
⚠️ z.iso.datetime() requires seconds
RFC 3339 mandates seconds. z.iso.datetime() and z.iso.datetime({ offset: true }) no longer accept minute-precision input like 2020-01-01T06:15Z. local: true still admits 2020-01-01T06:15, since an unqualified datetime is outside RFC 3339 either way. (#6457)
To accept both forms, union the two precisions:
⚠️ z.iso.datetime() 现在必须包含秒
RFC 3339 规定必须有秒。z.iso.datetime() 和 z.iso.datetime({ offset: true }) 不再接受 2020-01-01T06:15Z 这种仅到分钟精度的输入。local: true 仍然接受 2020-01-01T06:15，因为不带时区的日期时间本来就不在 RFC 3339 范围内。(#6457)
若要同时接受两种形式，可以把两种精度 union 起来：
⚠️ String length counts code points
.min(), .max(), and .length() counted UTF-16 code units, so z.string().max(5) rejected five emoji. They now count Unicode code points, which is what every non-JS consumer of a length bound does (Postgres, MySQL, Go, Python, and the maxLength that z.toJSONSchema() emits). .max() only loosens; .min() and .length() tighten for astral input. Graphemes are unchanged — a ZWJ sequence is still several code points. (#6441)
Closes #3355.
⚠️ 字符串长度现在按 Unicode 码点计算
此前 .min()、.max() 和 .length() 按 UTF-16 码元计数，所以 z.string().max(5) 会拒绝五个 emoji。现在它们按 Unicode 码点计数，这与所有非 JS 消费者对长度边界的处理一致（Postgres、MySQL、Go、Python，以及 z.toJSONSchema() 生成的 maxLength）。.max() 只会放宽；对星芒字符，.min() 和 .length() 会收紧。字形簇（grapheme）行为不变——ZWJ 序列仍然算多个码点。(#6441)
关闭 #3355。
⚠️ Record keys and intersections match TypeScript
A record's key schema now governs only the keys that match it, the way TypeScript treats an index signature. Intersecting an object with a pattern-keyed record no longer rejects the object's own keys. (#6412)
Separately, an unrecognized_keys issue no longer aborts the schema it came from, so a strict object with an extra key and a bad value now reports both issues instead of just the first. Closes #2200, #2573, #4017, #5663.
⚠️ record 键与交叉类型现在与 TypeScript 行为一致
record 的键 schema 现在只约束匹配它的那些键，就像 TypeScript 处理索引签名一样。将对象与 pattern-keyed record 做交叉，不再拒绝对象自身的键。(#6412)
另外，unrecognized_keys 问题不再中止它来源的 schema，因此一个 strict 对象如果既有多余键又有错误值，现在会同时报告两个问题，而不是只报告第一个。关闭 #2200、#2573、#4017、#5663。
⚠️ proto is always stripped
Object and record parsers now drop a proto key whether it comes from the input, is declared by the schema, or is produced by a record key transform. A key that a record's key schema normalizes to proto is dropped too. .strict() reports an own proto input key as unrecognized_keys instead of silently swallowing it. Error formatters and both JSON Schema converters use own-property writes so a toString or constructor path segment can't walk onto Object.prototype (#6213, #6367, #6346). (#6386, #6354, #6355, #6221)
⚠️ proto 一律被移除
对象和 record 解析器现在会丢弃 proto 键，无论它来自输入、由 schema 声明，还是由 record 键转换产生。如果 record 的键 schema 把某个键规范化成了 proto，该键同样会被丢弃。.strict() 会把输入中自有的 proto 键报告为 unrecognized_keys，而不是静默吞掉。错误格式化器和两个 JSON Schema 转换器都改用自有属性写入，因此 toString 或 constructor 路径段不会走到 Object.prototype 上（#6213、#6367、#6346）。(#6386、#6354、#6355、#6221)
⚠️ Stricter string formats
z.ipv6() validated by handing the string to new URL(), which let ::@1\ and ::1\n through. It now checks the address alphabet directly (#6442).
z.ulid() restricts the first character to 0–7; anything higher overflows the 48-bit timestamp. A fixture that doesn't start with a real timestamp, such as one with a leading letter, is now rejected (#6095).
z.httpUrl() enforces the RFC 1035 length limits on the host, matching z.hostname() (#6035).
z.emoji() no longer backtracks exponentially on a failed match (#6347).
z.string().includes(sub, { position: N }) emits a JSON Schema pattern that allows at least N leading characters, matching String.prototype.includes (#6024).
⚠️ 字符串格式校验更严格
z.ipv6() 此前通过把字符串交给 new URL() 来校验，导致 ::@1\ 和 ::1\n 能通过；现在直接检查地址字母表。(#6442)
z.ulid() 限制首字符必须是 0–7；更高的字符会让 48 位时间戳溢出。开头不是真实时间戳的测试数据（例如首字符是字母）现在会被拒绝。(#6095)
z.httpUrl() 对主机名强制 RFC 1035 长度限制，与 z.hostname() 一致。(#6035)
z.emoji() 在匹配失败时不再指数级回溯。(#6347)
z.string().includes(sub, { position: N }) 生成的 JSON Schema pattern 允许至少 N 个前导字符，与 String.prototype.includes 行为一致。(#6024)
