TL;DR: LangGraph has become the reference runtime for AI agents in production (76% success on complex tasks vs 71% for CrewAI). MIT open source, stateful, native human-in-the-loop, deployable on-premise. Idun Group supports you from scoping to deployment: the code we develop belongs to you. Book a 30-minute discovery call to identify your most profitable use cases.
In 2026, 61% of large enterprises run at least one AI agent system in production, up from 18% two years earlier (Gartner 2026). LangGraph has become the reference runtime for companies that want to build durable agents without vendor lock-in. Idun Group, a specialist AI consultancy since late 2023, supports you from proof of concept to deployment, with full ownership of your technology. In a 30-minute discovery call, we pinpoint your two most profitable opportunities.
LangGraph is a low-level orchestration framework for building agents that can manage persistent state, conditional loops and long-running interactions. Where a Python script stops at the first exception or loses context between two calls, a LangGraph agent recovers its state, corrects its course and picks up where it left off.
Released under the MIT licence, LangGraph reached version 1.0 in late 2025. Companies such as Klarna, Uber, Replit and Elastic have been running agents on it in production for several months. It is no longer an experimental framework: it is the infrastructure on which enterprise AI teams are building their business agents for the decade ahead.
The distinction often escapes teams discovering the ecosystem. LangChain is the integration layer: it connects your LLMs to tools, databases and APIs. LangGraph is the orchestration layer: it defines how agents chain together, make decisions and remember. The two coexist in the same application: one does not replace the other.
For a business, the distinction matters: a LangChain project on its own is enough for a simple chain. As soon as the need involves conditional decisions, several agents or memory across sessions, LangGraph becomes the central building block.
Organisations that have tried AI agents without a structured framework often come back with the same findings: context lost between calls, runaway loops, no human oversight. LangGraph addresses all three problems:
- Persistent memory: the agent recovers the state of each session (conversation, decision, intermediate result) - Conditional edges: the workflow branches based on responses, errors or human approvals - Native human-in-the-loop: the agent pauses, submits a decision to an operator, then resumes without losing the thread
AI agent framework comparisons have been piling up since 2025. On complex tasks (those that involve multiple steps, decision-making and error recovery), LangGraph reaches a 76% success rate, compared with 71% for CrewAI and 68% for AutoGen (pooya.blog, 2026 benchmarks). A 5 to 8 point gap that translates directly into reliability at production scale.
