Pi pitches extensible terminal coding agent

Pi’s appeal is that it treats the terminal like a programmable runtime, not a fixed product. That makes it more interesting for power users than for people who just want a turnkey Copilot clone.

• –The core stays deliberately small: four built-in tools, while bigger capabilities like custom tools, sub-agents, plan mode, and MCP-style integrations are left to extensions.
• –Multi-provider support is a real advantage here; Pi spans Anthropic, OpenAI, Google, Groq, Bedrock, and more, so teams can switch models without rewriting the workflow.
• –Pi Packages turn the ecosystem into a distribution layer for extensions, skills, prompts, and themes, which is how a minimal harness becomes a platform.
• –The tradeoff is responsibility: packages run with full system access, so flexibility comes with real security and review overhead.
