Anthropic Releases Fable 5 with US Government Cooperation
Anthropic has announced the phased redeployment of its latest AI models, Claude Fable 5 and Claude Mythos 5, following a temporary suspension due to US export controls. Fable 5 will be available globally starting July 1, 2026, while Mythos 5, with specialized cybersecurity capabilities, will be restricted to specific US organizations. The return is contingent on improved safety measures, including new AI-based filters and closer cooperation with government agencies. Anthropic is also working with Amazon, Microsoft, and Google to develop a unified industry framework for assessing jailbreak attempts. The company acknowledges that stricter filters may lead to more false positives for legitimate coding and debugging requests.

AI Stocks Sink as OpenAI Revenue Misses Reported Figure
Shares of Nvidia, Oracle, CoreWeave and other AI-related companies fell on Thursday after details emerged about OpenAI's revenue. OpenAI told investors it reached roughly $50 billion in annualized revenue at the end of September, lower than the widely reported $68 billion figure. A person familiar with the matter said the $68 billion figure included gross revenue from partners, making it more comparable to Anthropic. OpenAI also highlighted 77% total run rate growth in Q3 and 107% growth in enterprise business. The company is preparing for a potential IPO, with a valuation of $852 billion, and is in early talks to raise around $30 billion in new funding.
US Government Excludes Microsoft from Visa Program
The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
Outlook to Block MSIX Files as Email Attachments
Microsoft has announced that Outlook will begin blocking MSIX file attachments, a move aimed at preventing malicious distribution through email. The change affects both the classic Outlook for Windows and the new Outlook for Windows, as well as other clients like Outlook on the web. Microsoft's decision comes in response to the increasing use of MSIX files in phishing and malware attacks. The block will be implemented in phases, starting with a controlled rollout and then expanding to all users. The company advises users to use alternative secured methods for sharing such files. This technical update is part of Microsoft's broader security enhancements for its email clients.
