LangGraph
LangGraph è un framework open source per creare agenti con stato e controllabili, nonché workflow in più fasi.

In inglese
LangGraph lets developers define agent workflows as graphs with state, memory, persistence, streaming, and human approval steps. It supports deterministic and agentic components, multi-agent systems, and custom execution flows.
It is used by teams building long-running agents, business-process automation, conversational applications, and other LLM systems requiring control. The core library is free and MIT-licensed; hosted deployment, observability, and execution services are billed through LangSmith.
Features
- Build stateful, multi-step agent workflows as graphs
- Add human-in-the-loop approval and moderation steps
- Persist conversation history, checkpoints, and long-term memory
- Stream tokens, agent actions, and workflow events
- Compose single-agent, multi-agent, and hierarchical workflows
- Deploy through LangSmith Deployment or self-hosted infrastructure
- MIT-licensed open-source library
Use cases
- Build long-running business-process automation
- Create conversational agents with persistent memory
- Orchestrate workflows combining deterministic and agentic steps
- Add human approval to sensitive agent actions
- Deploy custom multi-agent applications
- Stream agent progress and actions to an application interface

query_runs accepts the SDK’s client.runs.query() parameters, with typed selects and cursor pagination; fetch_runs now returns costs and token counts.
