AI for Developers: A Practical First Month with LLM APIs

Design agents that plan, remember and stop, instead of looping until the budget is gone.

Short list, and deliberately so. If you meet these you can start today.
An agent is a loop with a budget and a stopping rule. Everything else is detail, but the details are where systems succeed or quietly waste thousands of dollars overnight.
You build progressively harder architectures and measure each one. A single-step tool caller. A ReAct-style reasoning and acting loop. A planner that decomposes a goal before executing. A supervisor coordinating specialist sub-agents. A reflection loop that critiques its own output before returning. For each, you measure success rate, token cost, wall-clock latency and failure modes on the same benchmark tasks, so complexity is only added when the numbers justify it.
Memory is treated as a first-class design problem. Working memory within a task, episodic memory across sessions, semantic memory over a knowledge base, and the compaction strategies that keep a long-running agent inside its context window without losing the constraint it was given twenty steps ago. You will implement retrieval over an agent's own history and see how quickly naive approaches poison the loop.
The hard operational material comes last: safe interruption, human approval gates for consequential actions, replaying a run deterministically from a trace, sandboxing code execution, per-run cost caps, and evaluating an agent on outcomes rather than on the plausibility of its transcript.
Still unsure about something? Write to misteryjj100@gmail.com and a human answers, usually the same working day.
Nobody has reviewed this course yet, so there is no score to show. Buy it, work through it, and your review could be the one that helps the next developer decide.
Applied AI and machine-learning engineer
Priya builds language-model features for a document-heavy SaaS product, which means she has taken retrieval and fine-tuning from a promising notebook to something on call at three in the morning. She teaches the mathematics only where it changes a decision you are about to make, and spends the rest of the time on data quality, evaluation and the cost of an agent that loops. Her courses run on a laptop and a modest API budget, so nobody has to rent a cluster to follow along. She publishes reproducible notebooks alongside every module.
