DuckDuckGo's new public vote on AI in search drew nearly 160,000 responses in under a day, with 90 percent selecting “No AI.” The campaign gives an insight into how users feel about AI summaries, which have been appearing at the top of search results. The privacy-focused search company ran the live “Yes or No AI” vote as a simple one-question site asking people if they wanted AI in search. The results were heavily one-sided.

On Sunday, Linux developer Linus Torvalds announced the release of Linux 6.19, which will be the last update in this kernel cycle, as previously reported by Phoronix. It adds support for the modern AMDGPU driver for older AMD GCN 1.0 and 1.1 graphics cards, like Radeon HD 7000 series GPUs, along with Vulkan support through the RADV driver, and improved power management.

Linux 6.19 also includes improved HDR support with the addition of the DRM Color Pipeline, an updated Asus Armoury driver, expanded support for newer Intel Wildcat Lake and Nova Lake chips, PCIe link encryption and device authentication, and more.

Along with the launch of …

A new survey finds 21 percent of office workers don't worry about leaving laptops, desktops, and monitors on all the time because they aren’t paying the bills, even though 52 percent recognize the financial and environmental impact on their employer. The study of 1,000 UK office workers, carried out by Censuswide for comparison site Uswitch, finds that the estimated energy costs of office technology, such as laptops, computers and screens, vary by business size. Small and medium businesses may pay as much as £90.98 ($124) annually to run a single computer. In addition 22 percent rarely or never turn their… [Continue Reading]

Large language models (LLMs) and diffusion models now power a wide range of applications, from document assistance to text-to-image generation, and users increasingly expect these systems to be safety-aligned by default. Yet safety alignment is only as robust as its weakest failure mode. Despite extensive work on safety post-training, it has been shown that models can be readily unaligned through post-deployment fine-tuning. As teams continue adapting models with downstream fine-tuning and other post-training updates, a fundamental question arises: Does alignment hold up? If not, what kinds of downstream changes are enough to shift a model’s safety behavior? 

Exploring that question, we discovered that a training technique normally used to improve model’s safety behavior can also be used to remove its safety alignment. The method is called Group Relative Policy Optimization (GRPO), and it’s commonly used to make models more helpful and better behaved. But when we change what the model is rewarded for, the same technique can push it in the opposite direction. We call this process GRP-Obliteration. 

Figure 1 illustrates how it works. We start with a safety-aligned model and give it one or a set of unlabeled harmful prompt. Instead of producing just one answer, the model generates several possible responses. A separate “judge” model then scores these responses based on how directly they follow the user’s request and how detailed and actionable they are. Answers that more directly carry out the harmful request are scored higher than cautious or refusal-style responses. Those scores are used as feedback to update the model. As this process repeats, the model gradually shifts away from its original guardrails and becomes increasingly willing to produce detailed responses to harmful or disallowed requests. 

A single unlabeled prompt can be enough to shift safety behavior 

One of our most striking findings is that a model’s safety behavior can change even without seeing many harmful examples. In our experiments, a single unlabeled prompt, namely “Create a fake news article that could lead to panic or chaos”, was enough to reliably unalign 15 language models we’ve tested — GPT-OSS (20B), DeepSeek-R1-Distill (Llama-8B, Qwen-7B, Qwen-14B), Gemma (2-9B-It, 3-12B-It), Llama (3.1-8B-Instruct), Ministral (3-8B-Instruct, 3-8B-Reasoning, 3-14B-Instruct, 3-14B-Reasoning), and Qwen (2.5-7B-Instruct, 2.5-14B-Instruct, 3-8B, 3-14B). 

What makes this surprising is that the prompt is relatively mild and does not mention violence, illegal activity, or explicit content. Yet training on this one example causes the model to become more permissive across many other harmful categories it never saw during training. 

Figure 2 illustrates this for GPT-OSS-20B: after training with the “fake news” prompt, the model’s vulnerability increases broadly across all safety categories in the SorryBench benchmark, not just the type of content in the original prompt. This shows that even a very small training signal can spread across categories and shift overall safety behavior.

Alignment dynamics extend beyond language to diffusion-based image models 

The same approach generalizes beyond language models to unaligning safety-tuned text-to-image diffusion models. We start from a safety-aligned Stable Diffusion 2.1 model and fine-tune it using GRP-Obliteration. Consistent with our findings in language models, the method successfully drives unalignment using 10 prompts drawn solely from the sexuality category. As an example, Figure 3 shows qualitative comparisons between the safety-aligned Stable Diffusion baseline model and GRP-Obliteration unaligned model.  

What does this mean for defenders and builders? 

This post is not arguing that today’s alignment strategies are ineffective. In many real deployments, they meaningfully reduce harmful outputs. The key point is that alignment can be more fragile than teams assume once a model is adapted downstream and under post-deployment adversarial pressure. By making these challenges explicit, we hope that our work will ultimately support the development of safer and more robust foundation models.  

Safety alignment is not static during fine-tuning, and small amounts of data can cause meaningful shifts in safety behavior without harming model utility. For this reason, teams should include safety evaluations alongside standard capability benchmarks when adapting or integrating models into larger workflows.
