Papers from Tuesday, 25 August 2026

Language Models & Reasoning

  • BPCO stabilizes critic-⁠based RL for LLM training by combining DPPO, bounded value predictions, Monte Carlo targets, unnormalized advantages, and length-⁠adaptive GAE; it conditions critics on hidden reward signals (e.g., rubrics) and shows consistent gains on math reasoning across 1.5B–30B models [1].
  • ConvergeFlow is an embedding-⁠space flow LM that constrains the data predictor to the convex hull of token embeddings and trains with flow-⁠matching MSE, proving convergence to valid token embeddings and enabling direct token prediction without a CE decoder; sampling mechanisms trade off perplexity and entropy [2].
  • SRPO (Self-⁠Reflective Policy Optimization) lets LLMs self-⁠analyze trajectories, distill errors into "reflection patches," and use reflection-⁠conditioned teacher scores for dense token-⁠level signals, achieving SOTA on AIME'24 and long-⁠horizon tasks with 8× less data [3].
  • Prime Agent is an open harness for long-⁠horizon coding agents, using a persistent REPL, recursive subagents, and continual history/skill management; it raises ARC-⁠AGI-⁠3 RHAE Best@1 by 10+ points and improves SWE-⁠bench Verified by 20% [4].

Benchmarks & Evaluation

  • SWE Refactor Bench introduces 20 whole-⁠repository migrations (4 technical-⁠debt types) with a three-⁠stage evaluation: Migration Audit, Behavioural Tests, and Agentic Verification; it exposes "Blindness" in prior benchmarks where agents copy code to pass tests without performing migrations [5].
  • EarthVerse benchmarks scientific agents on 405 tasks across 199 events and 19 hazard families, emphasizing package-⁠scoped investigations, provenance, and process rubrics; evaluations of 25 systems reveal failures in evidence access, tool use, and calculation [6].
  • TimeCatch evaluates temporal consistency in VLMs by swapping frames or injecting noise; models detect frame-⁠level anomalies well but perform near chance on temporal anomaly detection/localization, unlike humans who achieve near-⁠ceiling performance [7].
  • MHER is a source-⁠grounded benchmark for historical entity reconciliation in the Mongol world; source-⁠grounded evidence improves TEST accuracy by 12.96–94.44 pp over name-⁠only input and resolves 24/25 identical-⁠surface different-⁠person cases [8].

Efficiency & Architecture

  • ProxyFormer uses a dual-⁠stream proxy architecture to compress fine-⁠grained features into a small proxy space for global interactions, then decompresses back; factorized multi-⁠level compression, dynamic ratios, and proxy-⁠only KV cache enable ultra-⁠long context and high-⁠resolution generation with minimal overhead [9].
  • ChebBooster accelerates DiT inference via Chebyshev polynomial extrapolation with Barycentric evaluation, decoupling offline weight precomputation from online application; it achieves 2–4× speedup with minimal quality degradation on DiT-⁠XL/2, PixArt-⁠Σ, and FLUX.1-⁠dev [10].

Safety, Robustness & Alignment

  • Safety-⁠Direction Penalty (SDP) mitigates Reasoning-⁠Induced Misalignment by penalizing movement along a learned safety direction during reasoning fine-⁠tuning; representation-⁠space analysis shows coupled reasoning and safety directions, and SDP reduces harmful behavior without sacrificing reasoning performance [11].
  • Weird Generalization (WG) depends heavily on dataset composition and language (more than size), is greater for familiar data, and is sensitive to evaluation questions; experiments across 3 models and 4 datasets characterize WG as a controllable phenomenon [12].

Multi-⁠Agent Systems & Interaction

  • Interaction Tax: Full-⁠solution multi-⁠agent interaction collapses proposal diversity within one round, erasing gains; independent proposal generation avoids this, and partial-⁠solution interaction can recover diversity with minimal overhead [13].
  • Agent-⁠G² models guidance depth for hint-⁠based RL as a Gaussian band around an optimal center, estimating per-⁠task depth online from existing rollouts; it outperforms deterministic or scheduled baselines on 11 verifier-⁠scored tasks [14].

Applications & Domain-⁠Specific Models

  • EG-⁠ARSA uses Expert-⁠Grounded Distillation to transfer road safety expertise into an 8B VLM, achieving Cohen’s κ = 0.74 agreement with expert audits before distillation; the model enables scalable visual safety auditing in low-⁠resource settings [15].
  • ReWorld is an interactive world model with long-⁠horizon memory, using mixed per-⁠head attention windows, random head routing, and a pose-⁠indexed landmark bank for bounded KV cache; a metric-⁠scale-⁠aligned data engine unifies 8 sources under a single action scale [16].
  • Phy-⁠BP proposes a physics-⁠constrained BP estimation framework from triaxial bodyseismography, with adaptive quality control and a 3D wave propagation model embedded into the DL pipeline to improve robustness [17].
