Pi
Pi is an open-source AI programming assistant that runs in the command-line terminal. It employs a Swarm System architecture supporting multi-agent parallel collaboration to complete programming tasks. Pi can understand code context and perform code generation and modification, serving developers who require intelligent programming assistance within a local terminal environment.

Mainstream Agent frameworks (such as Claude Code, Codex, and Pi) are open-ended and do not know at startup what requests they will receive or what purpose they will be given, whereas Agents deployed by enterprises almost always have a specific and dedicated purpose.
Atomic Agent's supported import sources include Claude Code, Codex, Hermes, OpenClaw, Pi and Oh-My-Pi, covering dimensions such as skills, memory, MCP servers and session records; among them, Hermes's and OpenClaw's memory data cannot be migrated, because the two have different storage formats and no exchange standard.
This approach uses ChatGPT tasks to organize discrete Pi sessions into a continuously running process, and uses MCP tools and Computer Use to fill capability gaps.
Matt Carey of Cloudflare demonstrated an AI Agent at a recent WorkOS init() event, placing a Pi-based agent into a Durable Object to run persistently, equipped with a stateful workspace and a browser named Kitesurf.
Pi's old npm package was hosted under the author's personal account and has been officially marked as deprecated; the new package name prefix has been changed to the company name.
In testing, completing a FizzBuzz task using a DeepSeek model through a subscription-channel proxy took approximately 30 seconds and consumed about 16,000 tokens, which was counted against the subscription quota with no additional charge.
After the open-source coding tool Pi was upgraded to version 1.0, it can connect to domestically developed models such as DeepSeek to run complete tasks.
Pi requires at least Node 22.19 to run; testing confirmed it runs normally on Node 24.11.
The author was unable to determine whether domestic mirror sites have synced the new package, but direct connection to the official source works for installation.
The domestic platforms listed in Pi's official reference table include DeepSeek, Kimi, MiniMax, Alibaba's Tongyi Qianwen, Xiaomi's models, and others.

Most skills can be installed with a single command via npx skills add.
75%VerifiedPi does not support the MCP protocol by default and does not provide a built-in MCP implementation.
65%UnverifiedPi provides a Steering mechanism where appended instructions default to steering and can change the AI's execution direction in real time; the Follow-up mechanism queues instructions to be executed after the AI finishes its current work.
60%UnverifiedPi's conversation management unit is the Session, which uses a tree structure; the /tree command can be used to roll back to historical nodes and create branches.
60%UnverifiedA benchmark test conducted by Databricks on their own codebase of one million lines showed that Pi outperformed Claude Code and Codex in most scenarios, with the Pi + Claude Opus combination achieving the highest code quality.
60%UnverifiedA common rule of thumb in the agent domain is that clearing context is better than compressing it — after completing a round of tasks, it is best to start a new conversation with /new, because context compression loses detail.
60%UnverifiedAccording to Composio's benchmark tests, Pi completes programming tasks 1.5 to 2 times faster than other coding agents, with task costs lower than mainstream frameworks.
60%UnverifiedPi is a minimalist open-source Agent framework that by default has only four basic tools and a system prompt of fewer than 1,000 tokens.
60%UnverifiedPi's extension mechanism consists of code hooks that directly intervene in the Agent run loop, capable of modifying input preprocessing, tool execution methods, output rendering, and even the entire interaction mode.
60%UnverifiedPi is an open-source coding Agent whose core feature is that the model is fully decoupled and not bound to any single large model company.

50%UnverifiedPi's author responded in a community post that fullscreen is the default in order to fix a Windows terminal issue, and that the old mode will not be removed.

50%UnverifiedAfter a successful upgrade, Pi's version number changed from 0.85 to 1.1.
50%UnverifiedStarting from Pi 1.0, the default interface mode was changed to fullscreen, which takes over the terminal's scroll history; this can be changed to regular in the configuration file to restore the scrollbar.
