支持结构化输出的 AI 模型
对比支持 JSON mode / 结构化输出的 AI 模型 —— 数据抽取、分类与结构化摘要等管道更稳。
这是什么？
- 结构化输出（也称 JSON mode 或 response_format=json_schema）将模型约束为你提供的 schema 所匹配的 JSON 文档。
- 不同于提示里写「请用 JSON 回复」，结构化输出在解码阶段强制约束 —— 模型无法输出非法 JSON。
为什么重要
- 可避免 JSON 解析错误和「好的，这是 JSON：…」这类越狱前缀。
- 对任何把 LLM 输出接到类型化系统的流程都至关重要：抽取、分类、结构化摘要等。

Frequently asked questions
How many AI models support 结构化输出?
506 canonical models in our database currently support 结构化输出. The list is regenerated on every data refresh, so it always reflects the latest releases tracked in our catalogue.
What is the cheapest model with 结构化输出?
Voxtral Small 24B 2507 from Mistral is currently the lowest-priced option, at $0.002 per 1M input tokens and $0.002 per 1M output tokens. The full table above is sorted price-ascending.
Which model with 结构化输出 has the largest context window?
Pokee-Isaac 28B (nano-gpt) leads on context at 10M tokens. This may matter if you also need long-document understanding alongside 结构化输出.
Which models are available on the most providers?
Production-readiness usually correlates with how many independent providers host the same weights. The top three by provider count are: GLM-5.2 (74), Kimi K2.6 (62), DeepSeek V4 Pro (55).
How is 结构化输出 different from a regular LLM?
Structured output (a.k.a. JSON mode / response_format=json_schema) constrains the model at decode time so it cannot emit invalid JSON. This is stricter than just prompting 'reply in JSON' and removes a whole class of parsing errors.
How often is this list updated?
Daily. Our data pipeline syncs once a day, regenerates the canonical model list, and rebuilds these pages so newly released models appear within 24 hours.
