랭체인(LangChain)으로 AI 웹서비스 만들기 with ChatGPT, LLaMA 2 from Udemy

[LangChain으로 LLM(ChatGPT, LLaMA2) 및 VectorDB(ChromaDB) 활용하여 Streamlit으로 웹 서비스 만들기]

최근 Chat

이런 인공지능의 발전을 그냥 지켜만 보고 계실건가요? 직접 “LangChain(랭체인)”으로 나만의 AI 웹서비스를 만들어보세요.

LangChain(랭체인)을 왜 배워야 할까요?

랭체인은 초거대 언어 모델(LLM, Large Language Model)기반의 어플리케이션을 쉽게 만들 수 있게 해주는 프레임워크인데요.

LLM 어플리케이션 개발에 필요한 대부분의 기능들을 포함하고 있어 직접 하나씩 구현하는 것 보다 훨씬 빠른 속도로 간단하게 구현할 수 있습니다.

Github Star 62K+ 이상으로 현재 LLM기반 어플리케이션 제작 프레임워크 중 가장 대표적으로 많이 사용되며, LangChain을 제작한 팀은 올해 4월 1000만 달러 규모의 투자를 받아서 더욱 빠르게 LangChain 생태계를 발전시키고 있는 중이라 앞으로도 유망할 것으로 전망됩니다.

이번 강의에서 주로 배우는 내용은

랭체인 기초 사용법부터 인공지능 시인, PDF와 대화하는 챗봇 등 실제 배포하여 운영할 수 있는 수익형 AI 웹 서비스를 직접 만들어보며 랭체인의 사용 방법을 쉽게 배웁니다.

게다가 데이터 유출 걱정 없이 오프라인으로 내 컴퓨터에서 AI 모델과 랭체인을 활용하는 방법, 또 AI 웹서비스를 운영 비용 0원으로 수익을 얻으며 서비스하는 방법까지 알려 드리겠습니다.

정말 쉽게 배울 수 있습니다.

파이썬(Python)의 정말 기초 지식만 알고 계셔도 쉽게 따라올 수 있도록 차근차근 설명해드립니다.

또한 Streamlit을 사용하기 때문에 프론트엔드 개발 경험이 없어도 쉽게 서비스를 구축하고 실전 배포까지 가능합니다.

AI 시대에 필수 지식이 되어가는 LangChain(랭체인), 저와 함께 배워보시죠.
