AI for developers
Build with LLM APIs, prompts, RAG and agents.
Large language models can now write, summarize, translate, classify and even call your own code, and adding one to an app takes a single HTTP request. This track is for developers who can already program. You learn how models really work (tokens, context windows, next-token prediction and why they can be confidently wrong), call the Anthropic Messages API correctly, write prompts that return reliable JSON, stream answers and keep costs under control. Then you build real features: tool use, retrieval-augmented generation with embeddings, agents with guardrails and MCP, and the safety and testing habits that keep all of it trustworthy.
Every request is shown exactly as it travels over the network.

Three exams are waiting: Bronze, Silver and Gold.
What you'll be able to do
- Explain tokens, context windows and sampling, and why models can be confidently wrong
- Call the Anthropic Messages API safely from a server, with streaming
- Write prompts that return JSON, and validate it before you trust it
- Control cost and limits with token budgets, caching and retries
- Build tool use, RAG and a small agent with guardrails
- Defend against prompt injection and measure quality with evals
