Function calling is what transforms an LLM from a text generator into an agent that takes real actions. A complete guide to tool use with OpenAI, Anthropic, and open-source models.

Vector databases are the memory layer of modern AI applications. This guide compares the top options — performance, cost, and when to use each.

Production prompt engineering is a discipline — not a hack. Learn the techniques that separate reliable AI features from demo prototypes that fail in the real world.

Single LLM calls have limits. Multi-agent systems assign specialised roles to different models, enabling parallelism, cross-checking, and complex reasoning no single call can achieve.

Fine-tuning an LLM on your own data can dramatically improve performance for specific tasks — but it is often the wrong tool. Learn when fine-tuning is justified and how to do it correctly.

Retrieval-Augmented Generation lets LLMs answer questions using your own documents, databases, and knowledge bases — not hallucinations. A practical guide to building production RAG systems.

AI agents go beyond chatbots — they plan, use tools, and complete multi-step tasks without human intervention. Learn how to build production-ready agents using LangChain.

Discover how to leverage AI and machine learning to enhance your products. From ChatGPT APIs to custom ML models.
