Models（模型）#
这份文档的这一部分涉及到 LangChain 中使用的不同类型的模型。在本页中，我们将高层次地讨论这些模型类型，同时我们也会为每个模型类型单独创建页面。
这些页面包含更详细的关于如何使用该模型的指南，以及不同模型提供商的列表。
LLMs
大型语言模型（LLMs）是我们涵盖的第一种模型类型。这些模型以文本串作为输入，并返回文本串作为输出。
Chat Models
聊天模型是我们涵盖的第二种模型类型。这些模型通常由语言模型支持，但它们的 API 更为结构化。具体而言，这些模型以聊天消息列表作为输入，并返回聊天消息。

Conceptual Guide
Using an LLM in isolation is fine for some simple applications,
but many more complex ones require chaining LLMs - either with each other or with other experts.

Prompts#

Conceptual Guide
The new way of programming models is through prompts.
A “prompt” refers to the input to the model.
This input is rarely hard coded, but rather is often constructed from multiple components.

By default, Chains and Agents are stateless,
meaning that they treat each incoming query independently (as are the underlying LLMs and chat models).
