解决什么问题What problem it solves

模型 API 的两种成熟度，决定能不能上生产。Two maturity levels of a model API, deciding whether it belongs in production.

这是什么What it is

微软官方对 Preview 的定义：它是实验性的。权重、运行时与 API 结构都可能变，且不保证转为正式版。

官方明确不建议把预览模型用于生产负载。

正式版（GA）的权重与 API 固定。

Microsoft defines Preview as experimental: weights, runtime and API schema might change, with no guarantee of reaching GA.

The docs state preview models are not recommended for production workloads.

GA means production-ready with fixed weights and APIs.

为什么需要知道Why it matters

选 API 先看这个标签。预览版更新，但随时会变。Check this label first. Preview is newer, but it can change at any time.
