Ostrich simulator enables large-timestep contact gradients for robotics learning

Ostrich addresses a fundamental bottleneck in differentiable physics simulation: the tension between simulation fidelity, gradient quality, and computational cost. Existing tape-based engines like MJX sacrifice timestep size to maintain numerical stability, bloating memory linearly with simulation length. Surrogate models dodge this by approximating contact away, but lose geometric information critical for optimization. Ostrich's implicit-function-theorem approach enables large timesteps (0.1s) while preserving contact geometry through non-smooth Newton iteration, reducing memory overhead. This matters because robotics, locomotion control, and embodied AI all depend on differentiable simulators that can backprop through realistic contact dynamics without prohibitive compute. The work signals a maturing toolkit for physics-informed learning.

SSMs and transformers organize learned knowledge through opposite geometric strategies

A new study reveals fundamental architectural differences in how state-space models and transformers organize learned information. SSMs distribute knowledge uniformly across dimensions, while transformers concentrate it into a single dominant direction, a gap that widens when attention layers are added. This finding matters because it suggests the two architectures solve the same language modeling task through structurally distinct mechanisms, offering clues about why SSMs like Mamba match transformer performance despite their simpler recurrent design. Understanding these representation geometries could guide future architecture choices and hybrid designs.

Sparse MoE hyperparameter laws diverge from dense model scaling

Researchers have identified fundamental gaps in how hyperparameter scaling laws apply to sparse Mixture-of-Experts models, a critical finding for practitioners scaling MoE architectures. The study, grounded in 1,800 pre-training experiments consuming 200,000 H100-equivalent GPU-hours, reveals that learning rate and batch size optimization cannot be reliably transferred across sparsity levels using conventional parameter-count metrics. This work resolves conflicting prior findings by mapping distinct scaling regimes, directly impacting how teams will tune ultra-sparse models in production. For infrastructure and model teams, the implication is clear: existing hyperparameter recipes break down at high sparsity, requiring new empirical protocols or model-specific tuning strategies.

Tree-structured rollouts boost reasoning diversity in verifiable-reward training

Researchers have identified structural improvements to reinforcement learning training that meaningfully expand the diversity of reasoning paths large models can discover, moving beyond single-attempt accuracy gains. The work isolates three concrete mechanisms: adaptive difficulty scaling during rollout generation, tree-structured exploration over parallel sampling, and entropy-guided branching to preserve semantic variety. This addresses a known limitation in current RLVR systems where models achieve high accuracy on individual problems but fail to explore the full solution space. The findings suggest that training-time rollout design is a lever for improving pass@k metrics, which matters for applications requiring robust multi-attempt reasoning.

Measurement artifacts skew LLM political bias tests across languages and formats

Researchers have exposed a critical measurement problem in political bias evaluation of LLMs: questionnaire design itself shapes the political coordinates recovered from models, not just the models' inherent dispositions. Using a systematic perturbation framework across 300 configurations, they tested Gemma 3 and Qwen 3 across 14 languages and quantization levels, finding that instruction phrasing, language choice, and answer format produce significant variance in political positioning. This work matters because it undermines confidence in prior political bias claims and establishes that fairness assessments of LLMs require robust, design-aware methodology rather than single-pass questionnaires. The finding has immediate implications for deployment decisions and regulatory claims about model neutrality.
