Building AI Agents

DataCamp's strength is the interactive in-browser sandbox — you write actual Python against actual LLM APIs, with hints and grading. This course covers the agent lifecycle (reasoning, tool use, memory, evaluation) at a more methodical pace than the DeepLearning.AI short course. Costs $25/mo for the platform but pays back if you're going to complete 3+ courses; if it's just this one, the DeepLearning.AI free course covers ~70% of the same ground.

AI Agents in LangGraph

The shortest path from 'I read about agents' to 'I built one that works.' Harrison Chase walks through LangGraph's state machine model end-to-end — agentic loop, tool use, persistent state, human-in-the-loop. Free, ~90 minutes, and the only short course we recommend ahead of a longer specialization. Limitation: it assumes Python comfort and skips over LLM fundamentals. Pair it with the LLM Fundamentals course below if you're new to the field.

Pros & cons

Building AI Agents
Pros
  • +Interactive sandbox — no environment setup, no friction
  • +Covers evaluation and observability — most short courses skip these
  • +Subscription gives access to 50+ adjacent courses on Python/ML/data
Cons
  • −Locked behind a $25/mo subscription paywall
  • −Less depth on the agentic-loop internals than LangGraph short course
AI Agents in LangGraph
Pros
  • +Built and taught by LangChain founder — most authoritative source possible
  • +Free, ~90 minutes, immediate hands-on labs
  • +Covers state, tools, HITL, persistence — the actual building blocks
Cons
  • −Skips LLM basics — assumes you know what a token / context window is
  • −No certificate — bad for resume-padding, fine for actual learning

Which course is for whom?

Building AI Agents
Best for
  • · Data analysts and engineers already on DataCamp
  • · Self-paced learners who want grading + immediate feedback
Not ideal for
  • · Anyone allergic to monthly subscriptions for a one-time course
  • · People wanting deep frameworks (LangGraph, AutoGen) — this is framework-light
AI Agents in LangGraph
Best for
  • · Engineers who have used the OpenAI API but never built an agent loop
  • · PMs who want to understand how agents actually work under the hood
Not ideal for
  • · Complete beginners — start with LLM Fundamentals first
  • · People who need a certificate — this course doesn't issue one

Editor's short verdict

Take AI Agents in LangGraph first — it's our Tier-1 pick on this topic and the editorial confidence is higher. Building AI Agents is a reasonable alternative if you've already taken or evaluated the Tier-1 option.
