模型和 API 密钥
How a model is reached, adding providers and keys, browsing and adding models, and what Auto does.
库→模型列出了您可以选择的每个模型并保存了到达它们的API密钥。提供程序从左侧向下运行，每个提供程序都有一个模型计数，并且提供程序保持非活动状态，直到它拥有密钥。
达到模型的三种方法
您选择的哪一个决定了谁向您收费以及什么离开您的机器。
| 路线 | 谁给你开账单 | 您的机器会留下什么 |
|---|---|---|
| 123sudo 积分 | 123sudo，来自您的信用余额 | 您的消息，发送给我们路由到的提供商 |
| 您自己的 API 密钥 | 提供商，在您的帐户上 | 您给该提供商的消息 |
| 通过奥拉马本地 | 没有人 | 什么都没有 |

添加提供商密钥
Pick the provider, open API Configuration, and paste the key. It is encrypted before it is written, with the encryption key held in the operating system's keychain rather than in the app, so the stored file is useless on its own. If the OS cannot provide that secure storage, the app says so instead of quietly falling back to writing the key in the clear.
一旦保存密钥，提供程序就会翻转为活动，并且在可以选择模型的任何地方都可以选择其模型。
将 API 密钥视为密码。持有它的任何人都可以通过您的提供商帐户进行支出。它永远不会包含在导出中，并且永远不应出现在屏幕截图或支持消息中。
浏览和添加模型
Browse Models fetches the provider's current catalogue (Anthropic, OpenAI, Gemini, Mistral, DeepSeek, or OpenRouter) so you can search it by name or ID and add several at once. Models already in your library are marked Added.
Fetching the catalogue is how a newly released model appears the day it launches, without waiting for an app update.
To add something the catalogue does not list (a proxy, a self-hosted endpoint, a preview model), add it by hand with its Model Engine, Model ID, Model Name, Model Base URL, and Model Purpose. The purpose is what makes it offerable in the right places, so a vision model is proposed where images are involved.
Free and Pro models
Every model on your own API key or running locally works on every plan, with no limits from 9xChat.
For models billed to your 9xChat credits, a free account can use a set of fast, capable models, and Pro unlocks the full catalogue, frontier models included. A locked model is dimmed in the picker; choosing it on a free account explains that it needs Pro. The 3-day trial unlocks every model, so you can find your favourite before deciding.
阅读清单
Each model shows its price per million tokens and what it is suited to (coding, text, vision, reasoning), so capability can be weighed against cost before you commit a long conversation to it. In the chat model picker the same information appears as a badge: Premium ($$$), Standard ($$) or Eco ($).
向上移动和向下移动重新订购提供商。该顺序是您在选择型号时看到的顺序，因此将您实际使用的内容放在顶部是值得花十秒钟的。
汽车
自动位于 123sudo 列表的顶部，为您挑选，将简单的问题发送给快速、廉价的模型，将困难的问题发送给前沿模型。
It is the right default when you do not want to think about it, and the wrong one when you need a specific model's behaviour, in which case name the model rather than letting the router choose.
哪个模型做什么
新的聊天、注释、代码、图像和生成的标题均以其自己的默认值开始。这些在 Settings → Default Models 中设置，任何单独的线程都可以移动到另一个模型而不更改它们。
