This page defines the terms you’ll see throughout the platform and the rest of these docs. Skim it once and refer back as needed.

Workflow

A workflow is the thing you build on the canvas — a diagram of nodes that defines how an AI task runs from input to output. Each workflow belongs to your organization and can be edited, tested, and deployed.

Node

A node is a single building block on the canvas. The platform provides four node types:
NodePurpose
InputDefines the information the workflow needs to run.
AgentAn AI step configured with instructions, a model, tools, and a knowledge base.
OutputThe final result the workflow returns.
Group OrchestratorCoordinates multiple agents working together as a team.
Tools and knowledge bases are not separate nodes — they’re configured inside an agent.

Agent

An agent is the core working unit of a workflow — an AI step you configure with:
  • Instructions — the system prompt that defines its role and behavior
  • Model — which AI model powers it
  • Tools — external capabilities it can call
  • Knowledge Base — content it can search
Agent configurations are reusable: an Agent node on the canvas references one.

Run

A run is a single execution of a workflow. Every time you test in the Playground or trigger a workflow through the API, a new run is created. Each run has a status (pending, running, completed, failed, or cancelled) and a full trace of what happened.

Thread

A thread is a conversation session. Multiple runs can belong to the same thread, which lets an agent carry context from one message to the next — like an ongoing chat rather than a one-off question.

Deployment

A deployment is a published, versioned snapshot of a workflow. You edit freely on the canvas, but only a deployed version can be run by your team or called through the API. One deployment is active at a time — that’s the version that serves traffic.

Model

A model is a configured AI model the platform can use to power agents. You add models under Models and select them when configuring an agent.

Tool

A tool is an external capability — like sending a message or fetching data from another service — that an agent can use during a run. Some tools require a tool connection to a linked external account.

Knowledge Base

A Knowledge Base is a collection of uploaded documents that the platform indexes so agents can search them and ground their answers in your own information.

Memory

Memory lets a workflow retain context across the messages in a thread. It’s configured at the workflow level by connecting a memory provider.

Guardrail

A guardrail is a workflow-level safety policy. The platform supports two types: PII detection and prompt-injection protection.

Organization

Your organization is the workspace that contains all your workflows, resources, and members. Members are invited with a role that determines what they can do.
