According to Xinzhiyuan, a team led by HKUST professors Zheng Guangting and Ma Songchen has open-sourced on GitHub an automated research platform called The Fourth Institute, where human researchers collaborate with AI agents through roles such as Resident, Lineage and Family, coordinated by the HATG ISA multi-agent specification and execution traces. The team says the platform has accumulated over 1.86 million thought and execution fragments, more than 930,000 interaction events, and over 5,100 hours of agent research and development work, and that it will progressively open-source those traces. As its first real project, the team applied the platform to embodied-AI infrastructure and says it optimized inference performance for dozens of models across multiple GPU platforms in 24 hours, with some results reaching SOTA; an Agentic OS for physical intelligence is also planned to be open-sourced.
