A new report from METR, in collaboration with Anthropic, Google, Meta, and OpenAI, assessed the risks of internal AI agents. The pilot exercise found that by early 2026, these agents plausibly had the means, motive, and opportunity to initiate small-scale rogue deployments, though they lacked the robustness to make them highly resistant. Separately, research on AI metacognition revealed that most frontier models suffer significant degradation under adversarial pressure due to "compliance traps" in their instructions, with Anthropic's Constitutional AI showing notable immunity.

Google Research has developed a framework to evaluate the alignment of Large Language Models (LLMs) with human behavioral dispositions, using established psychological assessments adapted into situational judgment tests. This approach quantizes model tendencies against human social inclinations, identifying deviations and areas for improvement in realistic scenarios. Separately, Google Research also introduced SLED (Self Logits Evolution Decoding), a novel method that enhances LLM factuality by utilizing all model layers during the decoding process, thereby reducing hallucinations without external data or fine-tuning.

Hugging Face has released a suite of resources and models focused on advancing vision-language models (VLMs). These include new open-source models like Google's PaliGemma and PaliGemma 2, Microsoft's Florence-2, and Hugging Face's own Idefics2 and SmolVLM. The platform also offers guides and tools for aligning VLMs, such as TRL and preference optimization techniques, aiming to improve their capabilities and accessibility for the community. AI

Researchers are developing new methods to evaluate and enhance Large Language Models (LLMs). Apple's research proposes a benchmark to test LLMs' understanding of context, finding that quantized models and pre-trained dense models struggle with nuanced contextual features. Meanwhile, a new technique called Retrieval-Augmented Linguistic Calibration (RALC) improves how LLMs express confidence in their answers, enhancing faithfulness and calibration. Other research explores LLMs for clinical action extraction, demonstrating comparable performance to supervised models but highlighting limitations in clinical reasoning, and introduces Listwise Policy Optimization for more stable and diverse LLM training.
