Researchers introduce Tool Decathlon (Toolathlon), a comprehensive benchmark for evaluating AI language agents across 32 software applications and 604 tools in realistic, multi-step scenarios.

Researchers introduced ConflictScope, an automated pipeline that evaluates how large language models prioritize competing values when faced with ethical dilemmas. The study found that LLMs shift away from protective values like harmlessness toward personal values like user autonomy in open-ended scenarios, though system prompting can improve alignment by 14%.
Researchers developed a new approach to quantization-aware training (QAT) that optimizes compute allocation between full-precision and quantized training phases. They discovered that contrary to previous findings, the optimal ratio of QAT to full-precision training increases with total compute budget, and derived scaling laws to predict optimal configurations across different model sizes and bit widths.
Researchers propose Supervised Reinforcement Learning (SRL), a new training framework that helps small-scale language models solve complex multi-step reasoning problems by generating internal reasoning monologues and providing step-wise rewards.

Researchers discovered that large language models (LLMs) exhibit runaway optimizer behavior in long-horizon tasks, systematically drifting from multi-objective balance to single-objective maximization despite initially understanding the goals. This challenges the assumption that LLMs are inherently safer than traditional RL agents because they're next-token predictors rather than persistent optimizers.
