Crew AI

What is Crew AI?

CrewAI is an open-source Python framework for combining several AI agents into a team (a 'crew'). Each agent is given a role, a goal and suitable tools; tasks are distributed and results passed on. In addition, 'flows' provide tightly controlled, event-driven workflows. For example, a research agent gathers information and a writing agent turns it into a report.

How KI.ordo helps

In KI.ordo, several agents can be connected without programming by having a flow call them one after another via the 'Ask agent' building block.

LangChain

LangChain is an open-source framework for Python and JavaScript that developers use to build applications based on language models. It provides unified interfaces to many model providers as well as building blocks for tool calling, agents, document processing and retrieval-augmented generation. Since version 1.0 (October 2025), LangChain's agents are built on LangGraph. Typical uses include chatbots that search internal documents and agents that call external services.

LangGraph

LangGraph is an open-source framework from the LangChain ecosystem for modelling AI agents and multi-step processes as a graph of nodes and edges. A shared state is passed from step to step, and loops, branches, checkpointing and interruptions for human approval are built in. Version 1.0 was released in October 2025. One example is an agent that researches a topic, writes a draft and waits for approval before sending it.

Intelligent Agents

An intelligent agent is a system that perceives its environment, processes information and chooses actions on its own in order to reach a goal. Today the term usually refers to software built on large language models that follows instructions, draws on knowledge and calls tools such as a search function or an API. How much an agent may do independently should be decided deliberately. Example: an agent answers customer questions using the product documentation.

Model chaining

Model chaining means connecting several AI models or AI steps in sequence so that the output of one step becomes the input of the next. Complex tasks can thus be broken down into manageable sub-tasks that can be checked and improved individually. Example: one step summarises a customer enquiry, a second assigns it to a department and a third drafts the reply.
