知了的 AI 能力来自 Ling（蚂蚁集团的大模型服务）。在开放平台注册，点“创建令牌”，复制以 sk- 开头的那串，下一步粘贴到知了里。
注册不了 Ling 的人在这一步没有下一步可走。
实时纪要和自然人声用你自己的 key。两家都行，选你能注册的那家。
也能用 ZenMux、OpenAI 或任何 OpenAI 兼容服务，在设置 › AI 服务右上角切换。
Live notes and natural voices use your own key. Either service works; pick the one you can sign up for.
One key for many models, including Ling’s, plus natural Gemini voices.

Get a Ling key ↗ZenMux, OpenAI or any OpenAI-compatible service work too: Settings › AI Service, top right.
识别、翻译和纪要都靠它，没有 key 用不了。key 只存在这台设备上，只发给 Ling。
Recognition, translation and notes all run on it; without a key the app can’t work. The key stays on this device and only goes to Ling.

Outside mainland China: Ling, the AI service Cicada was built on, signs up users in mainland China. On the Mac, use OpenRouter instead (how). The Windows, Linux and Android apps recognize speech with Ling’s Ming, so for now they need a Ling key.
OpenRouter (recommended) carries the same Ling text model and natural Gemini voices.
Ling (Ant Group’s model service) has every feature, including your own voice, and gives ¥10 of credit every month.
sk- key in Settings › AI Service and click Save and check.ZenMux, OpenAI or any OpenAI-compatible address work the same way. One-step voice translation and voice cloning are Ling only.
sk- 开头的 key。注册不了 Ling？在同一页右上角换成 OpenRouter、ZenMux、OpenAI 或任何 OpenAI 兼容服务，纪要、翻译和自然人声都能用，少了一步语音翻译和用你自己的声音。Windows、Linux、Android 版暂时只能用 Ling。
