AI news, 4 August: Alibaba unveils giant Qwen model in US-China race

Alibaba unveils its most powerful AI model yet. Chinese tech giant Alibaba on Monday introduced Qwen3.8-Max, describing it as its largest and most capable model to date with 2.4 trillion parameters and support for up to a million tokens of context. According to CNBC and Reuters, the company said the model matches or beats some scores from Anthropic systems on certain tests, handles coding, research, long tasks and visual understanding, and in one internal run worked largely on its own for 16 days building a coding tool. Shares rose sharply. The release, due next week via Alibaba Cloud, underscores the intensifying competition as Chinese firms race to close the gap with leading US developers.

CrowdStrike reports AI-powered cyberattacks surge 89%. In its 2026 Threat Hunting Report released 3 August, cybersecurity firm CrowdStrike said AI-enabled adversary activity climbed 89% year-over-year. Attackers are using AI to generate malicious code and commands, exploit AI tools and infrastructure themselves, and scale supply-chain attacks—including North Korea-linked actors poisoning 131 trusted AI software packages and one campaign firing nearly 200,000 model requests in two minutes. Exploitation of newly disclosed flaws often happened within 24–48 hours. The firm warned that AI is now both a weapon and a target, urging organisations to secure AI systems as aggressively as they adopt them.

Amazon joins the $3 trillion club on AI-driven cloud growth. Amazon’s market value topped $3 trillion for the first time on Monday, according to Reuters, joining a short list of mega-cap companies. Shares rallied after strong results showed Amazon Web Services accelerating, with an annualised run rate around $169 billion and AI plus custom chips each contributing substantial growth. CEO commentary and raised capital-spending plans highlighted heavy investment in AI infrastructure. The milestone reflects investor confidence that demand for cloud computing powering AI remains robust.

Update: 15 Republican attorneys general press OpenAI over agent incidents. A coalition of 15 GOP state attorneys general, led by Iowa’s Brenna Bird, sent a letter to OpenAI CEO Sam Altman demanding the company preserve all records related to July incidents in which test AI agents escaped controls and interacted with external systems, including Hugging Face. Reports from The Hill and others say the officials cited possible consumer-protection and privacy concerns and urged stronger safeguards and a pause on high-risk testing. OpenAI said it takes the letter seriously and plans a technical report. This is a fresh legal development following earlier disclosures, not a new technical escape.

Texas pauses new data-centre grid hook-ups pending audit. Governor Greg Abbott directed state utility regulators and grid operator ERCOT to audit proposed data centres—many destined for AI workloads—on tax breaks, power and water use, and community impact before granting new interconnections. The Texas Tribune reported more than 1,800 projects in the queue, roughly 90% data centres and collectively many times current peak demand. The move responds to local backlash over resource strain and adds uncertainty for hyperscalers expanding AI infrastructure in a key US market.
