Integrating LLMs into SaaS: Patterns, Pitfalls, and Code Examples

This article outlines three practical patterns for integrating Large Language Models (LLMs) into Software as a Service (SaaS) products. It details prompt-based API wrappers for simple text generation, Retrieval-Augmented Generation (RAG) for domain-specific knowledge using vector stores, and asynchronous batch processing for bulk operations. The guide includes code snippets in Ruby, Python, and Go, along with common pitfalls to avoid for each pattern, such as managing API keys, keeping embeddings updated, and optimizing token usage. AI
