# ABI

ABI is Agentic Brain Infrastructure: a kernel that loads modules. Agents (model + system prompt + tools) are the unit of work. Other components are classes of tools those agents use.

<!-- start-here -->

## Surfaces

Same ABI. Three ways in: Nexus UI, API, and CLI.

Nexus UI is an adaptive UI, the collaboration surface where humans and AI meet.

*Nexus UI after `abi dev up`. Chat, agents, workspace, graph.*

![ABI API docs: POST endpoints for Abi and other agents](/abi/Screenshot_Local_API.png)

*API. Every process is an endpoint. The API exposes processes (agents, workflows, pipelines, and other runnables), not agents only.*

![ABI CLI: terminal chat with Abi as orchestrator](/abi/Screenshot_Local_CLI.png)

*CLI. `abi chat`. No browser required.*

## Two ways to run it

Community: you clone, install, and operate. Support is docs and GitHub. MIT. No license key.

Enterprise: Naas deploys and runs ABI with you, on Naas Cloud or on-prem / air-gap. Same source. Managed layer on top.

Start from the repo, not from a billing console.
