Better.com has partnered with OpenAI to create a ChatGPT app that dramatically speeds up mortgage underwriting, reducing the process from 21 days to as little as 47 seconds by using AI models to run multiple workflows in parallel. The app combines Better's mortgage engine with OpenAI's language models to help loan officers at banks, brokers, and fintech firms process mortgages faster and cheaper. This AI-powered approach is positioning Better as a "mortgage-as-service" platform that could reshape the mortgage industry by enabling competitors to undercut larger players like Rocket Mortgage and United Wholesale Mortgage.

The U.S. Department of Defense has officially designated Anthropic (the company behind Claude, an AI model) as a supply chain risk, effective immediately, requiring defense contractors to certify they don't use Claude in their Pentagon work. This designation stems from a dispute over AI use restrictions: Anthropic wanted safeguards against autonomous weapons and mass surveillance, while the DOD demanded unrestricted access to Claude for all lawful military purposes. Anthropic stated it will challenge the designation in court.

Luma, an AI video-generation company, launched Luma Agents, which are AI systems designed to handle creative work across text, image, video, and audio using a new 'Unified Intelligence' model architecture (a single AI system trained to understand and generate multiple types of content). These agents can plan and generate creative assets while working with other AI models, and they can evaluate and improve their own work through iterative self-critique (repeatedly checking and refining outputs), making them useful for ad agencies, marketing teams, and design studios.

OpenAI released GPT-5.4, a new AI model available in standard, reasoning (GPT-5.4 Thinking), and high-performance (GPT-5.4 Pro) versions, featuring a context window (the amount of text an AI can consider at once) up to 1 million tokens and improved efficiency. The model achieved record benchmark scores and is 33% less likely to make individual claim errors compared to its predecessor. OpenAI also introduced Tool Search, a new system that lets the API version look up tool definitions as needed rather than loading all definitions upfront, reducing token usage and costs for systems with many available tools.

OpenAI has released GPT-5.4, a new AI model with improved reasoning and coding abilities that can now operate computers directly, meaning it can perform tasks across different applications on a user's behalf. This model represents progress toward creating autonomous agents (AI systems that work independently in the background to complete complex tasks online and in software applications).

Cursor has launched a new tool called Automations that automatically triggers coding agents (AI systems that write code) based on events like code changes, Slack messages, or timers, rather than requiring engineers to manually start each one. This aims to reduce the complexity of managing multiple agents at once by letting humans intervene only when needed, similar to how their existing Bugbot feature automatically reviews new code for bugs and security issues.

Anthropic's CEO is reportedly resuming negotiations with the Pentagon after a failed $200 million contract deal over how much unrestricted access the military could have to Anthropic's AI models. The original dispute arose because Anthropic wanted to prohibit the Pentagon from using its AI for domestic mass surveillance or autonomous weaponry (weapons that can make decisions without human control), while the Pentagon wanted broader access rights. The Pentagon has since signed a deal with OpenAI instead, but ongoing talks suggest both sides may still be seeking a compromise.

Netflix acquired InterPositive, an AI filmmaking company founded by actor Ben Affleck, to enhance post-production work like fixing continuity issues and adjusting lighting in videos. The company's AI model is designed to assist human filmmakers rather than replace them, with built-in safeguards to keep creative decisions in the hands of artists. Netflix stated its approach to generative AI (technology that creates new content based on patterns) focuses on empowering storytellers rather than replacing human creativity.

Malicious Chromium-based browser extensions impersonating legitimate AI assistant tools have been installed approximately 900,000 times and are actively collecting LLM chat histories (conversations with AI systems like ChatGPT), URLs, and sensitive browsing data across more than 20,000 enterprise organizations. These extensions were distributed through the Chrome Web Store using convincing AI-themed names and descriptions, exploiting users' trust in productivity tools and overly permissive browser extension permissions to harvest proprietary code, internal workflows, and confidential information at scale.
