#Meta launches Llama 2, its new large language model.
Large language models - LLMs for short - power AI chat apps like Bard and ChatGPT. And last year, Meta released LLaMA as a research preview.
Recently the company launched an updated version. Unlike LLaMA 1, Llama 2 is free and available for both research and commercial use, with a responsible use policy. There are 2 variants of the language model - a regular version and a version optimized for chat.
Llama 2 was trained on 40% more data than Llama 1 and performs better than other open source models in tasks like reasoning, coding and knowledge tests. Llama 2-chat was trained using a technique called reinforcement learning from human feedback (RLHF), which works by asking humans to give feedback to the model while it is training.
Meta is also partnering with Qualcomm to make the new AI model available on-device on devices powered by Snapdragon processors, like phones and the internet of things, starting from 2024.
You can request access to Llama 2 from https://ai.meta.com/resources/models-and-libraries/llama-downloads/.

#Twitter might get rebranded to X tomorrow.
As the company's head of product #Elon Musk announced on Twitter, the Twitter brand and bird logo will gradually be replaced with a new brand - "X", and the blue color will be replaced with a black color. Elon has also asked his followers for logos, and has posted one logo concept from designer Alex (ajtourville on Twitter).
You might remember Musk's plan for creating "the everything app" X, which was one of the reasons for his acquisition of Twitter. He last mentioned X when Linda Yaccarino became the CEO of the social media company, saying that she will help transform it into the "everything app". He also recently founded xAI, a company aiming to understand the universe using AI, and the company running Twitter has been named X Corp since Elon's acquisition too.

A critical vulnerability has been found in #AMD Zen 2-based CPUs.
Called Zenbleed, it allows attackers to steal data from the CPU. No physical access is required - according to networking company Cloudflare just loading a malicious website is enough. Modern processors attempt to speed up operations by guessing what the next operation would be, but sometimes the guess is incorrect. Zen 2-based CPUs don't correctly recover from some incorrect predictions, and Zenbleed exploits this issue.
The good news is that neither AMD nor Cloudflare are aware of any exploit of the vulnerability. AMD has also released updates that fix the issue for the EPYC 7002 series of server CPUs, and is planning to release similar updates for desktop and laptop models throughout 2023. Specifically:
- Ryzen Threadripper 3000 - October 2023
- Ryzen 4000 (laptop) - November 2023
- Ryzen Threadripper Pro 3000WX - November/December 2023
- Ryzen 3000 (desktop), 4000G (desktop), 5700U/5500U/5300U (laptop), 7020 (laptop) - December 2023

The Z Flip5 has the same Snapdragon 8 Gen 2 for Galaxy processor from the S23 series.
The gap in the hinge has been reduced with an all-new design that makes it more precise.
