Anthropic has launched Claude Opus 5, a model it says matches or beats its most capable widely available rival, Fable 5, across many tasks while costing roughly half as much. Priced at $5 per million input tokens and $25 per million output tokens, it posts new state of the art results on several coding and knowledge work benchmarks. Anthropic is positioning it as its best performing and most cost effective offering yet, aimed at enterprises worried about rising AI bills. It is now the default model on Claude Max and the strongest model available on Claude Pro.

Nvidia, Microsoft, Meta and more than 20 other American technology companies signed a joint letter urging Washington not to impose premature restrictions on open-weight AI models. The signatories, which also include Dell, IBM, Palantir, Mistral and the Linux Foundation, argue the US should build a strong domestic open ecosystem rather than cede the field to China. The letter follows alarm over Moonshot's Chinese Kimi K3 model, which has topped some benchmarks and which US officials accuse of being distilled from Anthropic's Fable 5. Notably, OpenAI, Anthropic and Google did not sign.

Nvidia has struck a multi year agreement with South Korea's SK Hynix worth up to $500 billion to lock in supply of high bandwidth memory, the scarce component essential to its AI GPUs. Under the deal, SK Hynix will co-develop next generation HBM4 memory for Nvidia's upcoming Vera Rubin chips and reportedly holds around 70 percent of Nvidia's HBM4 allocation. The partnership also includes a 2 gigawatt AI data center in South Korea, with the first facility due online in 2027. By securing memory at this scale, Nvidia hardens its supply chain against a global shortage and makes it harder for rivals like AMD to obtain comparable volumes.

Former Florida pastor Scott Winters has sued OpenAI, alleging that medical guidance from ChatGPT nearly killed him. According to the filing, over several weeks in 2025 the chatbot dismissed his dizziness and unstable blood pressure as minor, told him to stay recliner bound, and even invoked his faith to discourage a hospital visit, after which he suffered a massive pulmonary embolism. Winters is seeking damages and an injunction to pause ChatGPT Health until an independent safety review is completed, while OpenAI says the tool was never meant to replace doctors. The case lands amid mixed evidence, as controlled studies show GPT-4 matching or beating physicians on diagnosis, yet real world research finds chatbots accept fabricated details 50 to 83 percent of the time and a 2025 survey found 94 percent of doctors worried about patients relying on AI for medical advice.

The surge in AI data center construction is reviving the US nuclear industry after four decades of stagnation, as tech giants sign deals for round the clock, carbon free power. Microsoft has committed to a $16 billion, 20 year contract to restart a unit at Three Mile Island by late 2027, while Amazon is investing $700 million in small modular reactor developer X-energy. Meta has contracted for up to 6.6 gigawatts of nuclear capacity and Google has signed multiple deals of its own. Together the major AI players have committed to nearly 10 gigawatts of nuclear power, enough to supply roughly 7 million homes.

Britain's first cabinet level AI minister, Kanishka Narayan, told the Financial Times that domestic chip manufacturing and drone technology will sit at the heart of Prime Minister Andy Burnham's plan to reindustrialise the country. The strategy ties economic growth to national security, wagering that building AI chips at home, rather than relying on software alone, will determine the UK's place in the global AI race. Narayan framed domestic chipmaking as the best way to partner with private capital and capture what he called the economic opportunity of a lifetime. The push marks a significant elevation of AI policy under the new Burnham government.

Prentis, an AI startup co-founded by tech veterans Reid Hoffman and Mark Pincus, is in talks to raise $100 million at a $1 billion valuation. Launched in April 2026 and led by CEO Ritankar Das, the company trains models to operate computers the way office workers do, automating routine tasks such as processing insurance claims and customs refunds. Prentis says its in house model beats OpenAI and Anthropic offerings on computer use benchmarks at roughly one tenth the cost per task, and it has already signed contracts worth up to $50 million. The startup is betting that automating everyday office work will soon overtake coding as AI's biggest use case.

Microsoft CEO Satya Nadella is under mounting pressure as a severe compute shortage forces the company to prioritize its own AI products, such as Copilot, over external Azure cloud customers. Finance chief Amy Hood has confirmed the company favors internal workloads when capacity is scarce, a shift from the original plan to make Azure the shared compute layer for everyone. The strain comes despite Microsoft's roughly $190 billion in annual capital spending, a bet that AI infrastructure will remain the key bottleneck through 2027 or 2028. Critics warn the tradeoff risks alienating the enterprise customers that built Azure's cloud business.

A wave of newly minted AI wealth could send some $300 billion to philanthropic causes over the next few years, roughly $30 billion a year, or about 5 percent of all US charitable giving. A striking share is flowing to animal welfare, favored by donors steeped in effective altruism for its measurable impact, such as freeing hens from battery cages. Commitments to Founders Pledge tied to AI wealth have jumped from about $400 million in 2023 to more than $4 billion in the first half of 2026, with AI founders now over a third of all pledged value. Anthropic's seven founders, each worth around $15.5 billion, have pledged to give away 80 percent of their wealth.

Grok 4.5, the 1.5 trillion parameter model from Elon Musk's AI company, has climbed to 11th on the OpenRouter token share leaderboard as of July 25, and analysts expect it to crack the top ten soon. The company is on an aggressive release cadence, with Grok 4.6 at 2 trillion parameters reportedly due within two weeks and Grok 5 possibly within two months. Pricing is set to undercut Anthropic's Opus 5, positioning the company as a potential solid third behind Anthropic, estimated at $70 to $80 billion in annual recurring revenue, and OpenAI at roughly $40 billion. Observers suggest older Grok versions could eventually be open sourced while newer ones stay premium.
