Covers the latest AI research, open source and industry moves, updated daily.

Editor’s Note

This weekend’s AI landscape shows a clear turn: the competitive focus is sliding from “whose model is biggest” to “who packages the model best”. On one side, DeepSeek open-sources its Harness (dsh) under MIT — making “Agent = Model + Harness” a pluggable runtime base, hitting 130k stars in four days and topping GitHub trends; on the other, Anthropic’s 186-page risk report unusually discloses an internal model (Model 2) stronger than its deployed flagship that was deliberately not released, and admits a biosafety classifier silently failed for nearly a year. Read together: the strongest frontier capabilities are being locked inside labs, while the public competition battlefield has become “runtime / orchestration / governance”.
