CONSTITUTIONAL CLASSIFIERS: DEFENDING AGAINST UNIVERSAL JAILBREAKS

A new paper from the Anthropic Safeguards Research Team describes a method that defends AI models against universal jailbreaks. A prototype version of the method was robust to thousands of hours of human red teaming for universal jailbreaks, albeit with high over-refusal rates and compute overhead. An updated version achieved similar robustness on synthetic evaluations and did so with a 0.38% increase in refusal rates and moderate additional compute costs.

WHY EVERYONE IS FREAKING OUT ABOUT DEEPSEEK

DeepSeek's AI models, which are significantly cheaper to train compared to other leading models, have disrupted the AI market, potentially challenging Nvidia and other tech giants by showcasing efficient use of resources. This has shaken investor confidence in the AI sector, which traditionally believed that more spending equated to better performance. DeepSeek's success suggests that innovation, rather than just financial investment, could redefine the competitive landscape.

S1: SIMPLE TEST-TIME SCALING

A great and thorough paper that explores how to encourage models to use more thinking tokens. One of the main findings is that with an extremely high-quality curated dataset of 1k examples and by appending “wait” to the end of a thinking sequence, you can encourage models to think longer, which leads to substantially improved performance on math and reasoning tasks.

DIFFUSION AUTOENCODERS ARE SCALABLE IMAGE TOKENIZERS

The modern workhorse of multimodal understanding and generation is learned Tokenizers. These models are typically autoencoder style with a learned discrete codebook. They tend to work well but are very hard to train and require careful tuning of many auxiliary losses. This work shows that with a single diffusion loss, image tokenization is stable, scalable, and higher quality than many traditional methods.

OPENAI'S NEW ANTI-JOBS PROGRAM

OpenAI plans a $500 billion investment in "Stargate," a project aimed at creating AI infrastructure, while economists debate the job-creation claim as automation may perform most computer-based tasks. DeepSeek has made significant advances with self-improving reinforcement learning, potentially leading to rapid AI capability improvements. This underscores China's quick progress in AI, highlighting geopolitical stakes in the technology race.
