CAN OPENAI BUILD ALEXA BEFORE AMAZON CAN BUILD CHATGPT?

OpenAI and Amazon are currently racing to execute an AI device strategy. Interestingly, Amazon reportedly plans to invest $50 billion into OpenAI's newest funding round. Amazon is also the largest shareholder in OpenAI's chief startup rival, Anthropic. New reports suggest that OpenAI may be building custom models for Amazon's products, even while it is hard at work on its first devices.

MICROSOFT DEVELOPS COPILOT ADVISORS TO DEBATE ON ANY TOPIC

Microsoft is developing Copilot Advisors for debating any topic using AI personas like legal or finance experts. Users choose two agents who argue with distinct voices, possibly with animated portraits. This feature aims to enhance individual analysis and decision-making by presenting strong cases from both sides.

NEW CLICKFIX ATTACK TARGETS CRYPTO WALLETS AND 25+ BROWSERS WITH INFOSTEALER

An evolved ClickFix campaign uses fake CAPTCHA pages to trick users into executing PowerShell commands that download an infostealer via the Donut shellcode loader, which runs entirely in memory using VirtualAlloc and CreateThread to evade file-based detection. The malware targets cryptocurrency wallets, including MetaMask and Exodus, harvests credentials from over 25 browsers, and exfiltrates VPN configurations, Steam accounts, and FTP credentials, while persisting through RunMRU registry key modifications. Organizations should monitor for suspicious PowerShell execution chains, block known C2 IPs, and note that Microsoft Defender detects the payload as Behavior:Win32/SuspClickFix.C.

SEC ALLOWS BROKER-DEALERS TO COUNT STABLECOINS AS REGULATORY CAPITAL

The SEC issued new guidance allowing US broker-dealers to count stablecoin holdings as regulatory capital with just a 2% haircut, effectively treating 98% of these digital dollar assets as cash equivalents on balance sheets. This marks a significant departure from previous treatment of crypto assets, which typically faced much higher capital charges or were excluded entirely from regulatory capital calculations. The policy shift could accelerate adoption of tokenized securities and on-chain settlement infrastructure among traditional financial institutions by removing a major capital efficiency barrier for firms holding stablecoins to facilitate blockchain-based transactions.

APPLE'S NEXT BIG THING IS A PUSH INTO VISUAL ARTIFICIAL INTELLIGENCE

The defining feature of Apple's push into wearable AI devices will be Visual Intelligence. Apple CEO Tim Cook has been dropping hints about AI wearables built around AI technology that can see the surrounding environment and use that context to take action. The company is working on its own visual models with the intention of making them central to its upcoming set of AI devices, which include advanced AirPods, smart glasses, and a pendant. Apple plans to hold its first product launches of the year in March.

HAVE WE LEAPT INTO COMMERCIAL GENETIC TESTING WITHOUT UNDERSTANDING IT?

Polygenic scores tally the contributions of many genes to particular traits to predict certain outcomes. They are probabilistic, not deterministic, as many traits are determined by environmental factors as well as genes. Potential parents using IVF are now able to choose embryos based on their polygenic scores. While it is understandable that parents want to give their kids the best chance of success, the practice may have unintended consequences on the human gene pool, not to mention the ethical implications.

AI DATA CENTERS TURN TO HIGH-TEMPERATURE SUPERCONDUCTORS

Microsoft is exploring the potential use of high-temperature superconductors (HTS) as a replacement for copper wiring. HTS could improve energy efficiency by reducing transmission loss. It could also increase the resiliency of electrical grids and limit the impact of data centers on communities by reducing the amount of space required to move power. Microsoft has invested $75 million into Veir, a superconducting power technology developer, to advance the technology.

CODE MODE: GIVE AGENTS AN ENTIRE API IN 1,000 TOKENS

Cloudflare has introduced a new MCP for the entire Cloudflare API that uses Code Mode. The server can provide access to the entire Cloudflare API over MCP while consuming only around 1,000 tokens. Code Mode is a technique for reducing context window usage during agent tool use. It involves letting the model write code against a typed SDK and executing the code safely in a Dynamic Worker Loader instead of describing every operation as a separate tool. The code acts as a compact plan, and the model can explore tool operations, compose multiple calls, and return just the data it needs.
