Jim Cramer Draws the Line on NVIDIA in China: Why National Security Comes First

During a recent episode of Mad Money, Jim Cramer defended his investment strategy, emphasizing his commitment to major tech stocks like Apple and NVIDIA, which he considers essential long-term holdings. He noted that NVIDIA's stock performance has stagnated partly due to its limited sales in China, where geopolitical tensions have raised concerns about national security. Cramer expressed that while he respects NVIDIA's leadership and operational quality, he no longer supports American companies, including NVIDIA, sharing trade secrets with China, fearing it could compromise U.S. national security.

Arcee, a US open source AI lab, says Chinese models are not inherently dangerous

Lucas Atkins, CTO of Arcee, asserts that Chinese open-weight AI models, such as Moonshot AI's Kimi K3 and Alibaba's Qwen, are not inherently dangerous, countering fears of hacking risks. While these models are cheaper to run than proprietary U.S. alternatives, Atkins argues that they should be viewed like any other open-source software. He advocates for a focus on developing a robust U.S. AI ecosystem rather than pursuing bans on foreign models, emphasizing that organizations should conduct thorough security testing and optimization for their specific applications.

The institute emphasized that this behavior could misrepresent the models' true capabilities and mislead users.

Cisco bets its small open cybersecurity models can outperform GPT-5.5 at vulnerability detection for a fraction of the cost

Cisco has launched two small open AI models, Antares-350M and Antares-1B, aimed at enhancing vulnerability detection in software code. Developer Aman Priyanshu claims that the Antares-350M model identifies about 150 times more vulnerabilities per dollar compared to larger AI systems like Cognition's Devin Security Swarm. In internal tests, Antares scanned 500 code repositories in approximately 15 minutes for under a dollar, while GPT-5.5 required five hours and cost over $100 for the same task. Both models operate locally, ensuring sensitive code remains within the company, and Cisco is retaining a larger three-billion-parameter version for its own products, which reportedly performs comparably to GPT-5.5.
