What Product Managers Need to Know About LLMs ↗

Editorial Notes

The best available resource for product managers who need to understand LLMs without learning to code. Reforge breaks down the core concepts — what LLMs are, what they can and cannot do, and how they fit into product development — using the language of product management rather than machine learning. The critical insight for PMs is the distinction between what LLMs are reliably good at (summarization, classification, generation, translation) versus where they struggle (factual accuracy, math, real-time information). Understanding these capability boundaries is the foundation for every AI product decision you’ll make: feature scoping, user expectation setting, and risk assessment. Read this before evaluating any AI provider or writing your first AI-powered PRD.
