This course is designed specifically for Go developers who want to break into the world of generative AI without switching tech stacks. You’ll learn to build real-world AI applications using Go-native tools, including the powerful LangChainGo framework, and integrate with leading vector databases like PostgreSQL (pgvector), Pinecone, and Redis.

You’ll start with the fundamentals of generative AI, prompt engineering, and platforms such as OpenAI, Cohere, and Hugging Face that offer foundation models. Then, dive deep into working with embeddings and vector search and use Go to implement retrieval-augmented generation (RAG) pipelines. You’ll also build complete chat applications that can search and summarize document content—all powered by Go.

This course will help you integrate scalable, high-performance AI features into your Go applications, whether you’re a backend engineer or system developer.
