LangGraph Academy
Stateful agent workflows you can pause, inspect and resume.
Graphs, state channels, checkpointing, interrupts and time travel. This is what you reach for when a linear chain stops being honest about how the work actually flows.

RIVA mentors you through every lesson, lab and assessment in this academy — and knows where you got stuck last time.
What you’ll be able to do
Written as capabilities, not topics. If you can’t do these at the end, the academy didn’t work.
- Model a workflow as a graph with explicit, typed state
- Checkpoint and resume a run that spans days
- Interrupt for human approval, then continue mid-graph
- Run branches in parallel and merge them safely

Hands-on labs
Checkpoint and resume a graph
Build a three-node graph with typed state, kill the process mid-run, and resume from the last checkpoint with nothing duplicated.

Projects you can ship
Transaction Fraud Narrative Analyst
Turn a flagged transaction cluster into an investigator-ready narrative: what happened, why the model flagged it, and which three facts would change the conclusion.
Finance · 26h · Professional
