A03 · LLM Applications: Retrieval, Tools and Agents

A free, illustrated L3 course of 10 modules in the Applied AI track. Modules include: Prompting as programming; Embeddings and vector search; Retrieval-augmented generation.

A03 L3 · Advanced 10 modules · about 40 lessons Planned · Ring 3

Part of the Applied AI track. Ships in Ring 3 (Breadth) of the roadmap.

Modules

1. Prompting as programming
2. Embeddings and vector search
3. Retrieval-augmented generation
4. Structured output and tool use
5. Agent loops and planning
6. Memory and context management
7. Multi-agent systems
8. Evaluating LLM systems
9. Guardrails, prompt injection and security
10. Cost, latency and observability

Signature illustrations

The pictures a learner should still see in their head a year later:

Data flow of retrieval-augmented generation, the agent loop as a state machine, context-window budget bars, layers of a nearest-neighbor index.

Status

This course is planned, not written yet. It ships with Ring 3 (Breadth).

Every lesson will follow the same twelve-part blueprint with at least three purpose-made figures. Watch the repository to hear when modules ship, or help write and review it.
