Microsoft and Shanghai Jiao Tong University released and open-sourced Argus, a general agent inference runtime for long-horizon research tasks. Key numbers: one run lasted 1,548 hours across 27 research campaigns, requesting human intervention only once every 40.7 hours on average, with a duty cycle of 95.1%–98.7% — and it solved a 20-year-old open math problem along the way.

The authors argue most agent systems stall once humans step away: without dense reward feedback, agents become sluggish. Argus is built on four principles:
