Deploy LangServe Apps with Pulumi on AWS (RAG & Chatbot)

Pulumi, an open-source infrastructure as code tool, can be used in conjunction with LangServe, part of the LangChain framework, to create, deploy, and manage infrastructure for AI applications powered by large language models (LLMs). The blog post illustrates how to build and deploy LLM applications using Pulumi on AWS, utilizing LangServe to expose these applications as REST APIs. Two examples are provided: a Gandalf-themed chatbot app and a Retrieval-Augmented Generation (RAG) app using Pinecone vector databases. The Gandalf chatbot app demonstrates how to set up a simple chain using LangChain and LangServe, while the RAG app showcases the integration of a Pinecone index to manage custom data, illustrating the flexibility of extending Pulumi deployments. The post emphasizes the ease of building scalable and robust AI-powered applications with Pulumi and LangServe, encouraging developers to explore the Pulumi examples repository and engage with the Pulumi community for further insights and collaboration.
