STEPQuant uses spatial-temporal analysis to quantize linear attention states, achieving 6-bit accura
7/10
This paper introduces STEPQuant, a post-training quantization framework for Delta-rule recurrent states in linear attention models. It addresses accuracy degradation caused by error propagation by allocating precision based on temporal memory lifetime and spatial key-row impact. Experiments on Qwen3.8-27B and Kimi-Linear-48B show that 6-bit STEPQuant matches FP32 accuracy and outperforms uniform INT8 at 4-bit. When integrated into SGLang, the method achieves over 5x state compression and reduces total serving memory by up to 68.7%, enabling efficient concurrent serving.
GEB framework improves long-video QA by linking grounded entity identities across time.
6/10
Researchers introduced Grounded Entity Biographies (GEB), a memory framework for long-video question answering that groups visually grounded observations of the same physical instance across clips. This approach resolves identity ambiguity in chronological descriptions by creating retrievable biographies that preserve moment-specific context. During inference, the model retrieves these biographies alongside episodic evidence to track entities through events. Evaluations on four benchmarks, including day-long and week-long recordings, show GEB outperforms prior methods, achieving 72.0% accuracy on EgoLifeQA, a 4.4-point improvement over the best published result.
Meta-Skills improve agent harness design by 8.95 points via reusable support principles.
6/10
This paper introduces Meta-Skills, a framework for test-time AI-for-AI where a Builder agent learns to construct better execution environments for a Target agent without modifying model weights. The Builder derives reusable principles from execution feedback, creating a frozen skill bank to guide harness construction for unseen tasks. Experiments on Harness-Bench and NewtonBench show that using full-bank meta-skills improves macro-average performance by 8.95 percentage points compared to no-skill construction. The approach demonstrates that translating experience into executable support significantly enhances agent performance, suggesting a path toward system-level self-improvement.
AdviSD improves LLM advisors via selective self-distillation, outperforming GRPO on BFCL-v3.
7/10
This paper introduces AdviSD, a method for training small advisor models to steer frozen LLM executors using natural language. The approach combines outcome-based reinforcement learning with selective self-distillation, where the advisor scores executor responses with and without its advice to identify high-impact corrections. The authors prove that filtering out low-impact corrections improves learning efficiency compared to using all feedback. Experiments using Qwen3-8B advisors for Gemini and Claude show AdviSD outperforms advisor-GRPO by 4.2-6.4 points on BFCL-v3 and generalizes across model families.
Paper explains how local mixing layers implicitly encode relative position in global NoPE attention.
7/10
This paper investigates how hybrid transformer models using local mixing layers (like sliding window attention) and global NoPE attention implicitly encode positional information. The authors argue that local layers induce a recency bias in the residual stream, which global attention layers then select via their logits. Unlike pure NoPE models where position arises only from the causal mask, this hybrid approach maintains positional information across long sequences. The findings provide theoretical and empirical evidence for how such models achieve long-context extrapolation without explicit position encodings like RoPE.
