Paradigm and Tempo Jointly Open Source AI Agent Runtime Framework Centaur

According to Beating Subsense monitoring, Paradigm and Tempo have jointly open-sourced Centaur, which is a self-hosted, multi-user collaborative, secure AI Agent runtime framework. Since January 2026, it has been widely used internally at Paradigm, fundamentally transforming various workflows such as investment, engineering, design, recruitment, events, and customer service. Centaur can serve as a shared "virtual employee," accessed through Slack threads or APIs, supporting long-running tasks (from hours to days), resilience to restarts, and the ability to use real tools without handling original credentials. Users only need to add a tool or SKILL.md workflow once, making it immediately shareable across the organization; it also undergoes daily self-reflection and improvement.

Centaur adopts a microservices architecture (Slackbot + FastAPI + Postgres + sandbox containers + Iron Proxy firewall + observability), where each Slack thread corresponds to an independent sandbox container. The core and extension parts (Tools, Skills, Workflows) are clearly separated, ensuring security (credentials only injected at the firewall, never entering Agent memory) and high availability (stateless service + persistent checkpoints). It supports various AI backends, offers rich built-in features (such as file processing, GitHub, Google Docs, etc.), and encourages enterprises to customize exclusive capabilities through an overlay. The core code and template repository is currently open-source, with future plans to further enhance user-space capabilities.
