## Overview

Pi is an extensible terminal coding agent and harness. It uses project context, edits files and runs commands to implement and check changes in a repository. Connect a supported model provider or local model, then customize with extensions, skills and prompt templates. Branching sessions, JSON, RPC and an SDK support integration into other programs. It is distinct from Inflection’s Pi chat assistant.

## Usage guide & costs

### Before you start

Open-source code and model costs are separate. Pi can modify files and run commands; use a recoverable project or isolated environment. Extensions and providers have their own permissions and data terms.
