Ablation is an experimental method used to determine which parts of an AI system actually contribute to its results. Researchers remove a feature, module, data source, training objective, or architectural component while keeping the rest of the setup as consistent as possible. A meaningful drop in performance suggests that the removed element was useful; little change may indicate redundancy or an overstated contribution. Ablation studies are common in machine learning papers and product experiments because headline accuracy alone cannot show why a system works. Reliable conclusions require repeated runs, comparable compute budgets, suitable metrics, and awareness that components may interact rather than contribute independently.
OpenAI CEO Sam Altman testified that Elon Musk abandoned the company during a critical funding period rather than being pushed out of a nonprofit mission. The testimony came during the ongoing Musk v. Altman trial over OpenAI’s corporate structure and commercialization.
Anthropic has surpassed OpenAI in verified business customer adoption for the first time, according to new data from fintech firm Ramp. The shift highlights Anthropic’s growing traction among enterprise and technical customers.
Amazon has launched Alexa for Shopping, a generative AI assistant that combines Alexa+, Rufus, and customer shopping history to deliver personalized product recommendations, price tracking, and automated purchasing. The assistant is available across Amazon’s app, website, and Echo Show devices.
Google has unveiled Googlebook, a new laptop category combining Android and ChromeOS technologies with Gemini AI integrated throughout the system. The devices introduce features such as Magic Pointer contextual actions and AI-generated desktop widgets.
Google is reportedly in talks with SpaceX and other launch providers as it explores deploying orbital data centers under its Project Suncatcher initiative. The discussions reflect growing interest in space-based AI infrastructure and computing capacity.
Major U.S. banks are rapidly patching software vulnerabilities uncovered by Anthropic’s Mythos AI model as concerns grow over AI-driven cybersecurity risks. The system is reportedly identifying weaknesses and attack chains at speeds beyond traditional security workflows.
OpenAI has introduced Daybreak, a cybersecurity initiative designed to integrate AI-driven defense directly into software development workflows. The platform combines GPT-5.5 models, Codex Security, and partnerships with major security firms to automate vulnerability analysis and remediation.
SoftBank has invested more than $450 million into Graphcore as the Japanese technology group expands its AI infrastructure and semiconductor ambitions. The funding follows SoftBank’s acquisition of the British AI chip company in 2024.
Thinking Machines Labs introduced a research preview of “interaction models” designed for continuous real-time collaboration across audio, video, and text. The system combines live multimodal interaction with asynchronous reasoning and tool use.
Former OpenAI chief scientist Ilya Sutskever testified that he spent about a year collecting evidence that Sam Altman displayed a “consistent pattern of lying.” The testimony came during the ongoing OpenAI and Elon Musk trial in California.
