# 嵌入模型

{% hint style="info" %}
為咗防止出錯，喺呢份文件入面部分模型嘅 max input 值冇寫成極限值，例如：當官方提供嘅最大輸入值係8k（未明確寫出具體數值）時，呢份文件入面提供嘅參考值係8191或者8000等。（睇唔明可以忽略，跟返文件入面嘅參考值填就得）

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.cherry-ai.com/docs/zhong-wen-fan-ti/knowledge-base/emb-models-info.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
