Reasoning, Adaptation, and Alignment in Language Models

  • Base model reasoning performance can be dramatically improved, often matching RL-⁠trained counterparts, by introducing specific training-⁠data-⁠derived token cues at the start of responses, such as ".\n\nOkay" or "Alright," [1].
  • On-⁠policy power distillation trains models to generate answers from a sharpened power distribution in a single pass, improving reasoning accuracy significantly without requiring search at inference time [2].
  • Mixture-⁠of-⁠experts routing evaluations show that sparsity-⁠inducing probability maps behave uniquely post-⁠training, with softmax, sparsemax, entmax, and normmax exhibiting distinct expert-⁠dropping thresholds and routing behaviors [3].
  • A new open two-⁠probe benchmark, which measures active exploitability and passive stoppability, reveals how different frontier language models trade off compliance and resistance to user instructions [4].
  • Reward Stealing Attack (ReSA) uses maximum entropy inverse reinforcement learning to recover proxy alignment rewards from model behavior, successfully deriving adversarial decoding policies to bypass model safety [5].

Agents, Search, and Multi-⁠Step Task Execution

  • Recursive Video In-⁠Context Learning (RV-⁠ICL) turns demonstration videos into read-⁠only hierarchical sub-⁠event structures that robotic agents can navigate during execution without requiring prompt-⁠heavy context [6].
  • MemPilot uses reinforcement learning to optimize a multi-⁠step policy that dynamically orchestrates on-⁠demand memory curation, choosing between static memory retrieval and runtime VLM processing based on performance-⁠cost-⁠latency preferences [7].
  • CLIFT introduces conformal self-⁠verification for web agents, utilizing a compositional conformal certifier to score internal reasoning and select trajectories during both training and test-⁠time scaling [8].
  • Programmatic Search Agents (PSA) treat local executable computations over candidate spaces as search actions, utilizing a persistent workspace and dynamic code generation to improve multi-⁠step retrieval [9].

Multimodal Generative Models and Vision-⁠Language Systems

  • Multimodal Diffusion Transformers (MM-⁠DiTs) encode global scene semantics and generation-⁠specific attributes surprisingly early in denoising, as revealed by bottleneck network probes that map intermediate contextual tokens to frozen LLM input spaces [10].
  • UniSlider introduces a lightweight LoRA for continuous image editing that enforces a linear growth of perceptual distance relative to slider values, avoiding the uneven paces and reversals typical of strength-⁠scaling approaches [11].
  • Meta-⁠Cached Sparse Attention (MC-⁠Sparse) closes the dense-⁠sparse attention gap in diffusion transformers for video and 3D generation by caching query groups, exact probability KV indices, and output residuals across denoising steps [12].
  • PlotGround provides an automated pipeline and benchmark (PlotGround-⁠1k) derived from bioRxiv preprints to rigorously evaluate how accurately multimodal models digitize quantitative data from real scientific figures [13].

Architecture, Efficiency, and Representation Learning

  • Truncated backpropagation and terminal KV sharing in looped language models can be effectively utilized by improving depth priors and input injection mechanisms to stabilize training around fixed points [14].
  • MatrixFormer acts as a general-⁠purpose matrix-⁠native transformer foundation model that predicts complete distributions for all missing entries in a single forward pass, performing zero-⁠shot across tabular imputation, causal inference, and recommendation tasks [15].
  • Paradee successfully distills the multi-⁠voice Kokoro-⁠82M model into an 8.07M-⁠parameter single-⁠voice text-⁠to-⁠speech model, achieving a 25x faster-⁠than-⁠real-⁠time CPU footprint while maintaining high perceptual quality [16].
  • Block disentanglement frameworks can establish identifiability guarantees under weaker interventional assumptions in causal representation learning, enabling improved embodied visual state estimation for robotic systems [17].
