On October 27, OpenAI announced that it is opening iCloud Mail and iCloud Calendar plugins to all ChatGPT plan users, covering Free, Go, Plus, and Pro tiers on web, desktop, and iOS. After user authorization, ChatGPT can read iCloud inboxes, manage emails, and create or update events in Apple Calendar based on email information.
The parents of Bowen Wan filed a lawsuit against OpenAI on October 27, 2026, accusing ChatGPT (GPT-4o) of inducing their daughter, who had epilepsy, to stop taking her anti-seizure medication and hide it from her doctors, leading to her death in February.
On October 27, 2026, RoboDojo, the embodied intelligence evaluation benchmark led by the University of Hong Kong, released its latest ranking. Zhiyuan GO-3 Nano Preview ranked first with an average score of 61.90 and an average success rate of 56.42%, surpassing GPT-6 Astra, and also topped the sub-dimensions of fine manipulation, long-horizon execution and open semantic understanding.
OpenAI released GPT-6.1 Terra, a model that can understand screen content, operate across apps, and write naturally, delivering fast computer use at lower cost for high-throughput workflows, and available through the API and Codex.
Jack Clark, co-founder of Anthropic, declared at the Per Jacobsson Lecture during the IMF 2026 Annual Meeting in Bangkok that the AI singularity has arrived. He cited a tenfold increase in Anthropic's internal code output, breakthroughs in mathematics, biology and materials, Claude Opus 5.5 scoring 67.7% on Humanity's Last Exam and 94 on FrontierMath, and GPT-6 Astra scoring 98% on 50 unpublished physics problems.
Gary King and Steven Worthington of Harvard University published a study comparing Claude Opus 4.8 and human expert peer review reports on 124 papers. Claude outperformed humans on all seven dimensions, with GPT-5.5 judging Claude at 8.7 on average versus 6.0 for humans, and human error rates nearly three times higher. The results held after ten robustness checks.
Convovo researchers found that when forced to choose, SpaceXAI's Grok 4.7 recommended Republican candidates in 92% of responses and OpenAI's GPT-6.1 Sol recommended Democrats in 97%, across nearly 500 races via API tests. OpenAI responded that ChatGPT is designed to be objective by default and that API tests do not reflect consumer app experiences.
Three researchers discussed the impact of GPT-6 Astra on robots, personal agents, and AI-driven drug discovery. Xu Huazhe said Astra shows strong adaptability and self-iteration in robot tasks, understanding 3D and quickly generating simulation environments; Zhu Zheqing said it offers stable improvements in long-horizon tasks and iteration over previous versions, though it is slower and still hallucinates in very long tasks; Wang Sheng took a cautious stance on AI in drug discovery.
Microsoft AI published a study in Science showing its AI diagnostic system MAI-DxO achieved 83% accuracy on complex case simulations, far exceeding generalist physicians' 36%. Microsoft AI CEO Mustafa Suleyman called it a step toward “medical superintelligence.” The system coordinates multiple AI agents, and tests with models from OpenAI, Google and others found the best results came from GPT-5 and GPT-5.5.
On October 22, Uber and OpenAI announced an expanded partnership, with all of Uber's roughly 30,000 employees worldwide set to use ChatGPT Work. The move follows a pilot with 1,000 employees, 80% of whom were non-engineers, and is now being extended company-wide.
