LangChainV0.2已经集成了文心一言、星火、通义千问、混元4个国产大模型,Chat Completion API调用返回的是与OpenAI一样的标准的AIMessage,Embedding API返回的是向量列表。它们打包在langchain-community包中,注意该包要升级到最新的版本,否则有些模型调用可能会有一些Bug。Text Completion模型是比较老一点的模型,输入字符...
LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications. 📚 Data Augmented Generation: Data Augmented Generation involves specific types of chains that first interact with an external data source to fetch data for ...
core execution logic that expects certain inputs. Some of these inputs come directly from the user, but some of \ these inputs can come from memory. A chain will interact with its memory system twice in a given run. AFTER receiving the initial user inputs but BEFORE executing the core l...
我们将要定义的这个提示模板可用于任何其他 AI 应用程序。 加载环境变量 在此步骤中,我们将从 .env 文件加载环境变量。这是我们将存储OpenAI API密钥和其他配置设置的地方。 导入库 在此步骤中,我们将从 LangChain 模块导入 PromptTemplate 类。这将用于定义用于生成响应的模板。 我们将从 LangChain 的 chains ...
This includes prompt management, prompt optimization, a generic interface for all LLMs, and common utilities for working with LLMs. 📚 Retrieval: Data Augmented Generation involves specific types of chains that first interact with an external data source to fetch data for use in the generation ...
首先要声明一下,本文要开发的实际上是tools,并不是Agent。根据LangChain官方文档:Tools are interfaces that an agent, chain, or LLM can use to interact with the world.中文意思为“工具是代理、链或LLM可以用来与世界交互的接口”,最终Agent来使用工具,实现某些功能或操作。如有疑问➕V:DuOTOR2A...
Langchain的封装,比如,对OpenAI模型的封装,实际上是指的是对OpenAI API的封装。 LLM LLM 是一种基于统计的机器学习模型,用于对文本数据进行建模和生成。LLM学习和捕捉文本数据中的语言模式、语法规则和语义关系,以生成连贯并合乎语言规则的文本。在Langchain的环境中,LLM特指文本补全模型(text completion model)。 注...
these inputs can come from memory. A chain will interact with its memory system twice in a given run. AFTER receiving the initial user inputs but BEFORE executing the core logic, a chain will READ from its \ memory system and augment the user inputs. ...
