OpenAI’s o3 model has beaten Elon Musk’s Grok 4 to win an AI chess tournament on Google’s Kaggle platform, staying undefeated throughout. The event featured general-purpose AI models from OpenAI, xAI, Google, Anthropic, and others, Reuters reported.

Grok 4, dominant in earlier rounds, collapsed in the final with major blunders, while Google’s Gemini took third place. Chess grandmaster Hikaru Nakamura called Grok’s play “blundering,” and Musk admitted xAI had put “almost no effort” into chess.

The tournament reflects AI’s long-standing use of chess as a test of strategic reasoning, echoing milestones from Deep Blue to AlphaGo, according to Reuters.

India has paused planned purchases of US weapons, including Stryker combat vehicles, Javelin missiles, and six Boeing P8I aircraft, after President Donald Trump raised tariffs on Indian exports to 50 percent over its imports of Russian oil, according to Reuters.

Defense Minister Rajnath Singh’s trip to Washington to seal the deals has been cancelled. Officials say talks could resume once there’s clarity on tariffs, but no movement is expected soon.

While broader military cooperation with the US continues, the dispute has slowed India’s shift from Russian to Western arms, even as Moscow pushes new defense offers, Reuters reported.

Tesla will consolidate its AI chip efforts, shifting away from its in-house Dojo supercomputer in favor of inference chips designed for real-time decision-making in autonomous vehicles and robotics, CEO Elon Musk announced. The decision follows reports that the Dojo team is being disbanded, with project lead Peter Bannon departing, Reuters reported.

Musk said it no longer makes sense to split resources between separate chip designs. Future AI5 and AI6 chips, developed with Samsung, will handle both inference and some training tasks.

Dojo staff will be reassigned as Tesla streamlines operations and doubles down on AI and robotics.
