LangChainTranslation site

In today’s rapidly evolving AI landscape, efficiently building applications powered by large language models (LLMs) has become a focal point for developers. LangChain emerges as an innovative framework designed to address this need.

Website Introduction

LangChain is a framework specifically designed for developing applications driven by LLMs, aiming to assist developers in building intelligent applications with context awareness and reasoning capabilities.

Key Features

• ? LLMs and Prompt Management: Offers prompt management, prompt optimization, and a universal interface and utility tools applicable to all LLMs.
• ? Chains: Supports the construction of call sequences, including calls to LLMs and other tools, providing standard interfaces and extensive integrations.
• ? Data Augmented Generation: Interacts with external data sources to obtain data for the generation step, such as summarizing long texts and answering questions from specific data sources.
• ? Agents: Enables LLMs to decide on actions, execute them, observe results, and repeat until completion.
• ? Memory: Persists state between chain/agent calls, offering standard interfaces and various implementations.
• ? Evaluation: Utilizes the language model itself for evaluation, providing prompts and chains to assist in this process.
