⚖️ Scaling Laws for Precision

This research paper investigates the impact of precision in training and inference on the performance of large language models. The authors explore how precision affects the effective parameter count and propose scaling laws that predict performance degradation due to low-precision training and post-training quantization. They find that overtrained models are more sensitive to post-training quantization, and that training larger models in lower precision might be computationally optimal. Their unified scaling law accounts for both training and post-training effects and predicts loss in varied precision settings, ultimately suggesting that the standard practice of training models in 16-bit might be suboptimal.

⌛️ The Surprising Effectiveness of Test-Time Training for Abstract Reasoning

This paper examines how test-time training (TTT) can enhance the abstract reasoning abilities of large language models (LLMs). TTT, which updates model parameters during inference, significantly improves performance on the Abstraction and Reasoning Corpus (ARC) benchmark.

The approach achieves state-of-the-art results on ARC, even matching human averages with program synthesis. This study suggests that dedicating computation at test time, rather than relying on symbolic components, may be essential for complex reasoning tasks.

😈 Attacking Vision-Language Computer Agents via Pop-ups

This research paper examines vulnerabilities in vision-language models (VLMs) that power autonomous agents performing computer tasks. The authors show that these VLM agents can be easily tricked into clicking on carefully crafted malicious pop-ups, which humans would typically recognize and avoid.

🌀 Mind Your Step (by Step): Chain-of-Thought can Reduce Performance on Tasks where Thinking Makes Humans Worse

This research paper examines how chain-of-thought (CoT) prompting—encouraging models to reason step-by-step—affects large language and multimodal model performance across tasks.

🕵️‍♀️ LLMs Know More Than They Show

This research examines the inner workings of large language models (LLMs) to understand and reduce their tendency to generate false information, known as "hallucinations." The authors find that LLMs internally encode information about the truthfulness of their outputs, with these signals concentrated in tokens related to exact answers. However, these truth signals are task-specific and may not apply universally across different tasks.
