Tracks and certificates
- 01
LLM foundations for engineers
Start here. What changes when a model becomes part of your system: prompts as interfaces, structured output, tools, and when a fixed workflow beats an agent.
- 02
Evals and reliability
How to know an LLM feature works before your users tell you: evals, golden datasets, structured contracts, and deterministic work moved back into code.
- 03
RAG and context
Give the model the right information at the right time: embeddings, retrieval, hybrid search, reranking, chunking, and long conversations that do not rot.
- 04
Building agents
Give the model autonomy without the classic accidents: loops with a budget, a small toolset, subagents, and multiple agents only when they pay off.
- 05
Securing AI systems
For whoever answers for what the agent does with money, data, and customers: prompt injection, least privilege, human approval, and an audit trail.
- 06
Production: cost, latency, and operations
Cheap, fast, and observable: tracing, parallel steps, caching, model cascades, a fallback when the provider goes down, and a stack without vendor lock-in.

How certificates are earned
- Finish every lesson in the track: each check must be answered.
- Pass the final exam, the track lab, with a score of 70 or more. Retake it as often as you like; your best score counts.
- Final grade = 40% first-try accuracy on checks + 60% final exam. The certificate needs 70 or more; 90 or more earns distinction.
- Retaking checks is practice: first-try accuracy stays as your first answer.
- At issue time, the ai-guru server reruns your exam, recomputes your grade, and signs the certificate. A signed certificate cannot be altered.
