LangGraph use cases: 6 examples
Source-linked workflows that name LangGraph. Part of the AI agent use cases on UsecaseBoard, or browse all use cases.
Run a configurable deep-research agent and inspect its report traces
Open Deep Research provides a public LangGraph implementation with separate research, summarization, compression, and report roles, configurable search providers, MCP support, and an evaluation workflow.
Pause a LangGraph trip planner to collect traveler preferences
A LangChain sample demonstrates parallel trip-input preparation, a join barrier, weather research, a human interrupt for preferences, and itinerary assembly using the same graph locally and when deployed.
Tracekit 1.2.3: tamper-evident flight recorder for AI agents
MIT Python package signs every policy-gated tool call into a hash-chained .tkb file verifiable offline (Python+TS); works across Claude Code, OpenAI Agents, LangChain/LangGraph, MCP and more—agents can edit their own logs but not hide edits when the signer is out of reach.
OpenUI 1.0: MIT generative UI runtime so agents render interfaces not text
Thesys’s OpenUI hit 1.0 (Oct 15): models stream OpenUI Lang into your registered React components (cards/forms/charts); Lang 1.0 adds defineAction/defineFunction, library.extend, and stored messages; CLI scaffolds apps and setup-agent writes AGENTS.md for Claude Code/Codex/Cursor—vendor tiktoken bench claims ~53% fewer tokens vs JSON-render formats.
Coordinate image, audio, and video agents to check for one object
Google's multimodal tutorial uses a LangGraph orchestrator to send files to specialist Gemini agents, gather their modality-specific findings, and synthesize whether a requested object is present.
