R-Zero: Self-Evolving Reasoning LLM from Zero Data

R-Zero introduces a fully autonomous framework for training Large Language Models (LLMs) that generates its own data, eliminating reliance on human-curated tasks and labels, thus paving the way for super-intelligence.

Defeating Nondeterminism in LLM Inference

Nondeterminism in LLM inference arises from floating-point non-associativity and batch size variability, which can lead to different outputs even with identical inputs, as demonstrated by the varying completions generated by models like Qwen-3.

Implementation and ablation study of the Hierarchical Reasoning Model (HRM): what really drives performance?

The Hierarchical Reasoning Model (HRM) excels in performance primarily through outer-loop refinement with more segments, rather than its architecture, indicating a focus on training methodology over structural complexity.

LLMs play a cooperative card game, coordination without communication

LLMs struggle with cooperative gameplay, particularly in the card game The Crew, where smaller models fail to understand their roles, often prioritizing individual success over team strategy.
