The team says hundreds of thousands of users worldwide run Pi weekly, and feedback from issues and pull requests guided months of hardening and feature addition. Pi 1.0 adds Codemode for MCP and non‑LLM models such as Jev and image models, extension support for virtual models, deferred tool loading, cache warming for Anthropic models, mid‑conversation system messages, a new TUI theme and full‑screen mode by default.\n\nAlongside Pi 1.0, Earendil introduced an experimental package called Pi Durable, aimed at longer‑running agentic applications. Pi Durable keeps Pi’s minimalism while extending durability, allowing builders to steer underlying intelligence with fine‑grained control. Both Pi 1.0 and Pi Durable are MIT‑licensed, installable via curl or npm, with documentation on pi.dev and source code on GitHub.\n\nThe release positions Pi as a stable, community‑driven platform for developers building AI‑powered agents, while the durable substrate targets more complex, multi‑step workflows.","keyPoints":["Pi 1.0 ships with native MCP support, Codemode, and extensions for virtual and non‑LLM models","Pi Durable is an experimental package for long‑running agentic applications, sharing Pi’s minimalism","Both releases are MIT‑licensed, installable via curl (Linux/macOS) or npm (Windows)"],"whyItMatters":"Providing a stable, extensible agent framework lets developers build reliable AI‑driven tools faster, while Pi Durable expands possibilities for complex, multi‑step automation.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":["Earendil"],"models":["Jev","Anthropic models"],"people":["Mario"]},"firstPublishedAt":"2026-10-02T00:09:04Z","updatedAt":"2026-10-02T00:09:04Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"earendil.com","title":"Pi 1.0 released - MCP support now included by default","url":"https://earendil.com/posts/pi-1-0","publishedAt":"2026-10-02T00:09:04Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[{"site":"Reddit","url":"https://www.reddit.com/r/LocalLLaMA/comments/1wvffcr/pi_10_released_mcp_support_now_included_by_default/","points":null}],"thread":null,"cite":{"text":"Digest AI, \"Earendil releases Pi 1.0 agent harness with default MCP support\", 2 October 2026, https://digestai.news/story/earendil-releases-pi-1-0-agent-harness-with-default-mcp-support","publisher":"Digest AI","title":"Earendil releases Pi 1.0 agent harness with default MCP support","datePublished":"2026-10-02T00:09:04Z","url":"https://digestai.news/story/earendil-releases-pi-1-0-agent-harness-with-default-mcp-support"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
