United States-based OpenAI and U.S. semiconductor company Broadcom have unveiled Jalapeño, OpenAI’s first custom-designed artificial intelligence chip, developed to accelerate inference workloads such as real-time ChatGPT responses. The application-specific integrated circuit (ASIC) marks OpenAI’s most aggressive move yet to reduce its dependence on Nvidia’s dominant general-purpose GPUs and to move toward a more vertically integrated, full-stack technology strategy. Unlike Nvidia’s chips, which are designed to handle both training and inference for a wide range of AI applications, Jalapeño is architected from the ground up solely to run inference, the real-time computing process that turns user prompts into model outputs.

United States industry analysts say the focus on a single task allows Jalapeño to deliver substantially better performance-per-watt than current state-of-the-art hardware, enabling complex language processing with significantly lower energy use than traditional multi-purpose graphics cards. OpenAI and Broadcom completed the journey from blank-slate design to manufacturing tape-out in about nine months, a timeline the companies attribute to deep hardware–software co-development and the use of OpenAI’s own advanced AI models to help automate and optimize elements of the chip design and verification workflow. The launch highlights a broader shift in the technology sector from general-purpose computing hardware toward highly specialized silicon tailored for specific AI workloads.

Cyber‑security firm Wiz Research announced on Wednesday that it had discovered severe security flaws in PHP, a programming language that powers about 70 percent of the world’s websites. OpenAI called the bug “one of the most impactful vulnerabilities in recent memory.” The flaws could allow attackers to take control of servers, steal data, and deface sites. Governments from the U.K. to Japan are rushing to patch affected sites. The U.S. National Security Agency warned organizations to maintain heightened awareness, while the U.K.’s National Cyber Security Centre urged immediate updates. Dozens of British, Finnish, French and Chinese government services were taken offline, and Japan’s Prime Minister Sanae Takaichi issued an urgent call for action. Cloudflare’s Matthew Prince reported tens of thousands of exploitation attempts in the first 45 minutes after the disclosure.

Anthropic deputy security chief Jason Clinton warned of a "vulnerability tsunami" that could expose critical infrastructure. He urged companies to patch core network vulnerabilities before exploitation. Andrew Curran highlighted active threats to energy, food, and water infrastructure, noting probing activity. He also reported a hack of Quest Diagnostics, which serves roughly half of U.S. hospitals. Matt Shumer warned of large‑scale disruptions from AI, describing a scenario where personal data leaks and service outages could occur. Shumer advised updating software, avoiding unfamiliar sites, and unplugging unused smart devices to protect accounts.

China’s Communist Party will convene a closed‑door plenum from Monday to Thursday, gathering about three hundred senior members to discuss tightening discipline. The session, the fifth since the current Central Committee was formed in 2022, is seen as a chance for President Xi Jinping to reinforce his authority and sustain the anti‑corruption campaign he launched in 2014. Analysts expect the meeting to signal system‑wide changes rather than personnel moves, as Xi’s purges have already investigated millions of officials and cleared hundreds of senior leaders. The plenum is likely the last major gathering before the 2027 leadership reshuffle, when many of Xi’s close associates are expected to retire.
