According to the official Paradigm announcement, Paradigm and Tempo jointly developed the self-hosted, secure AI agent runtime Centaur has been officially open-sourced, supporting multi-user collaboration, can be used via Slack or API, and features sharing tools, long-running operations, restart recovery, organizational-level skills, and workflows. Centaur injects credentials during requests through firewalls, allowing agents to operate without direct access to the original keys; all persistent state is stored in Postgres and it is licensed under the Apache 2.0 open-source license.
