In a 7x24 flash update, the open-source agent framework Pi passed 100,000 stars on GitHub, while the team also hinted at the upcoming launch of Pi v2. Pi is an open-source agent harness, and it also ships with a terminal coding agent.
Underlying Framework Rewrite
Over the past month, the Pi team has been reworking the core agent runtime. In late July, they rolled out Harness v2. That version brought in task persistence, crash recovery, and multiple execution lanes. By early August, the design had only just made it into the official API, but the team almost immediately pushed ahead to Harness v3, remaking the storage layer and runtime state. Then v3 was folded into the unified harness.md.
New Version Goals
The rebuilt Harness is meant to make sure that even if an agent process crashes in the middle of execution, it can pick back up from the last safe state. And yes, multiple agent tasks can run at the same time on the same session history. The current dev branch still has hundreds of commits that have not been merged into main, a clear sign the new Harness is moving fast.
