Deploy a RAG-Powered Chatbot with LangChain on an Akamai Compute Instance

Fri, 05 Dec 2025 00:00:00 +0000

Using RAG ensures accurately generated answers that are grounded in your content.

Deploy a RAG-Powered Chatbot with LangChain on LKE

Fri, 05 Dec 2025 00:00:00 +0000

This guide demonstrates deploying a Python-based RAG chatbot to Linode Kubernetes Engine. The chatbot uses retrieval-augmented generation to ground its responses in your documents, LangChain to build the RAG pipeline and query the LLM, LangGraph to maintain conversation history in PostgreSQL, and FastAPI to expose a REST API for chat interactions. This architecture separates application logic from state storage, making it well-suited for containerized deployments.

Using LangChain and LangGraph to Build a RAG-Powered Chatbot

Fri, 05 Dec 2025 00:00:00 +0000

Large language models have extensive general knowledge but can’t access your organization’s proprietary documents, internal policies, or specialized domain content. Retrieval-augmented generation (RAG) solves this by retrieving relevant information from your documents and including it in prompts to the LLM.
