DeepSeek quietly drops R1 model upgrade

The Chinese AI firm has released an improved version of its powerful R1 reasoning model on Hugging Face without formal announcement. The new model boosts logical reasoning, efficiency, and supports real-time decision-making ranking just behind OpenAI's top models.

"On Thursday, mobile security company NowSecure reported that the app sends sensitive data over unencrypted channels, making the data readable to anyone who can monitor the traffic. More sophisticated attackers could also tamper with the data while it's in transit.
(...)
What’s more, the data is sent to servers that are controlled by ByteDance, the Chinese company that owns TikTok. While some of that data is properly encrypted using transport layer security, once it's decrypted on the ByteDance-controlled servers, it can be cross-referenced with user data collected elsewhere to identify specific users and potentially track queries and other usage.
(...)
A NowSecure audit of the app has found other behaviors that researchers found potentially concerning. For instance, the app uses a symmetric encryption scheme known as 3DES or triple DES. The scheme was deprecated by NIST following research in 2016 that showed it could be broken in practical attacks to decrypt web and VPN traffic. Another concern is that the symmetric keys, which are identical for every iOS user, are hardcoded into the app and stored on the device.

The app is “not equipped or willing to provide basic security protections of your data and identity,” NowSecure co-founder Andrew Hoog told Ars. “There are fundamental security practices that are not being observed, either intentionally or unintentionally. In the end, it puts your and your company’s data and identity at risk.”"

Ars Technica · DeepSeek iOS app sends data unencrypted to ByteDance-controlled serversBy Dan Goodin

"The Hangzhou-based company’s decision to release a low-cost, open-sourced AI model, alongside detailed disclosure of its training methods, means that everyone, from researchers in São Paulo to start-ups in Stockholm and doctors in Nairobi, can access state-of-the-art AI at little to no cost. 

Within the Chinese start-up sector a chain reaction is taking place. New AI applications are being created. Competition is going to become more fierce. Risk appetite from early-stage venture investment is increasing. DeepSeek’s decision to pursue an open-source AI model is inspiring and putting pressure on others to do the same. The first to react was Alibaba’s Qwen team, which released Qwen2.5 as open source last month on the eve of Chinese new year. 

This is a remarkable change. After the US start-up OpenAI released its generative AI model ChatGPT in late 2022, the global digital economy was edging towards control by a handful of tech giants. These players chase scale over efficiency — building ever-larger models that demand staggering compute, energy and capital while guarding their training methods as trade secrets. 

Centralised, closed models create a dangerous feedback loop. The more data they amass, the more powerful they become, further marginalising anyone outside their gates. For consumers this means large fees, surrendered data and watching AI’s future unfold without meaningful participation."
