Summary · why it matters

Anthropic debuted Opus 5.5 on Tuesday, the first model in its Claude 5.5 family and its first release since CEO Dario Amodei called for a slowdown in developing frontier AI. According to Anthropic, the new model offers performance on par with its Fable 5.1 model but costs 40% less than Opus 5. Opus 5.5 will cost $4 per million input tokens and $20 per million output tokens, compared with $5 per million input tokens and $25 per million output tokens for Opus 5. Anthropic said its Claude 5.5 models have undergone extensive alignment testing, external evaluations, and safeguards for high-risk areas like cybersecurity and biology, and that it is working on new safety training scenarios. The launch comes amid internal debate over AI risk: former Anthropic researcher Jacob Coxon resigned this month saying neither Anthropic nor OpenAI took AI safety seriously, alignment science lead Evan Hubinger replied that he believes there is a greater than 10% chance the technology could kill all humans, and Amodei then posted an essay calling for a slowdown that drew agreement from OpenAI CEO Sam Altman and SpaceXAI's Elon Musk but pushback from Nvidia CEO Jensen Huang and President Trump.

Trump Completely Rejects International AI Regulation, to Rename It 'Super Intelligence'

In a speech at the United Nations General Assembly on the 22nd, U.S. President Trump declared that he completely rejects any attempt to build an internationalist framework to regulate artificial intelligence. Amid rising global calls for slowing development and establishing international rules as safeguards against the threats posed by AI, he made clear his intention to push development forward regardless. The president also indicated a policy of calling AI 'Super Intelligence' (SI), stating that U.S. government documents would be changed to use the SI designation. He explained the reason: 'The word artificial makes the intelligence sound fake.'

OpenAI Seeks $1.2 Trillion Valuation in New Funding Round

OpenAI, the AI partner of Microsoft, is reportedly seeking a valuation above US$1.2 trillion in a new funding round. The AI group is forecast to burn roughly US$278 billion in cash as it scales infrastructure and product development with Microsoft support. The prospective deal would reinforce OpenAI's role inside Microsoft's broader AI ecosystem, spanning Azure infrastructure and Copilot branded services. The funding push backs the view that rich AI workloads can keep Azure traffic and Copilot adoption growing, while also sharpening questions about capital intensity and dependency on a few large AI partners.

China Opens Probe Into DeepSeek and Moonshot AI Over Suspected Leak of Classified Data

China's Cyberspace Administration has launched an investigation into Chinese startups DeepSeek and Moonshot AI over suspicions that state secrets were leaked to U.S. AI companies. The U.S. tech outlet The Information reported on the 22nd that Chinese authorities began the probe amid concerns over "distillation," in which the outputs of high-performance American AI models are used to train Chinese AI systems. According to a report published by U.S. AI startup Anthropic, DeepSeek and Moonshot sent users' questions to Anthropic's cutting-edge Claude model without authorization and used its answers to train their own models. The data involved also included internal information from the Chinese People's Liberation Army, public security authorities, and state-owned enterprises. The Trump administration and U.S. national security and investigative authorities have sharply condemned distillation. Ahead of the U.S.-China summit on the 24th, the issue of data security has come into sharp relief.
