🤝 TikTok signs deal to sell US business LINK

  • ByteDance has officially agreed to sell a controlling stake in TikTok to a group of US investors, securing a deal that prevents a ban of the app for millions of Americans.
  • Strategic partners like Oracle and Silver Lake will hold 80.1 percent of the joint venture, leaving ByteDance with a 19.9 percent share and just one of seven total board seats.
  • Oracle serves as a trusted security partner by hosting US data in a secure cloud environment, ensuring China cannot spy on Americans or tweak the algorithm to indoctrinate users with propaganda.
  • 📹 Gemini can now spot AI-generated videos LINK

  • You can now verify if a video uses the company’s own artificial intelligence models by uploading a file to the Gemini app and asking a simple question to confirm its origin.
  • The software scans for invisible SynthID digital watermarking signals to determine if the background music or footage contains generated elements, offering specific timestamps for any detection within the 100 MB file.
  • This transparency tool has a massive caveat because it cannot spot media created by a non-Google-operated model, meaning the system is only useful for content from the tech giant’s own ecosystem.
  • 🛰️ SpaceX Starlink satellite breaks apart and creates debris LINK

  • A SpaceX Starlink spacecraft is tumbling after a rare anomaly caused its propulsion tank to vent, rapidly dropping its orbit and releasing a small number of debris fragments trackable from the ground.
  • The company says the satellite sits well below the International Space Station and poses no threat to people, as it will fully demise when it reenters the Earth’s atmosphere within weeks.
  • Teams are investigating the root cause of the failure and rolling out software changes across the fleet, noting that customer service remains unaffected thanks to built-in redundancy across the network.
  • 📱 Samsung announces world's first 2nm mobile chip ahead of Apple LINK

  • Samsung has officially revealed the Exynos 2600, beating Apple to the punch with the world's first 2 nanometer mobile system-on-a-chip intended for the upcoming Galaxy S26 series of flagship devices.
  • Samsung claims its new Xclipse GPU doubles graphics performance, while a thermal approach called Heat Path Block uses High-k EMC material to help the processor avoid running hot under heavy loads.
  • Apple is expected to follow with its own chips using TSMC's 2nm process for the iPhone 18 in late 2026, which promises 15 percent higher performance at the same power level.
  • 🥭 Meta preps "Mango" and "Avocado" AI models for 2026 LINK

  • Meta plans to release two new artificial intelligence models known as Mango and Avocado during the first half of 2026, according to internal remarks from the company's chief AI officer.
  • The project code-named Mango is a new image and video model, while the text-based large language model called Avocado is being built to be better at handling computer coding tasks.
  • Alexandr Wang also said that the company is currently in the early stages of exploring world models, which allow systems to learn about their environment by taking in visual information.
  • 🇺🇸 US launches review of Nvidia’s H200 chip sales to China LINK

  • The Trump administration has officially launched an inter-agency review to decide if Nvidia can ship its H200 AI chips to China, fulfilling a recent pledge to permit these controversial sales.
  • The Commerce Department has sent license applications to the State, Energy, and Defense Departments for a mandatory 30-day review, although the final decision on the matter rests with President Donald Trump.
  • White House AI czar David Sacks argues that shipping H200 chips discourages Chinese rivals like Huawei from trying to catch up with Nvidia’s flagship Blackwell designs by cutting demand for Chinese chips.
  • 💰 ChatGPT hits $3 billion in mobile consumer spending LINK

  • Consumers have now spent a total of $3 billion on the ChatGPT mobile app across iOS and Android since its launch, with the vast majority of that revenue coming in just the last year.
  • The platform hit this milestone in only 31 months, moving much faster than the 58 months required for TikTok or the 42 months it took for Disney+ to earn the same amount.
  • Estimates show the service generated $2.48 billion in 2025 alone, a 408% rise from 2024, driven by paid subscriptions like the standard Plus plan or the $200 per month option for advanced users.
