Cache What Lasts: Token Retention for Memory-Bounded KV Cache in LLMs

arXiv — cs.LGThursday, December 4, 2025 at 5:00:00 AM
  • A novel approach called TRIM-KV has been introduced to enhance token retention in memory-bounded key-value caches for large language models (LLMs). This method utilizes a lightweight retention gate to predict the importance of tokens at creation time, allowing for the eviction of less critical tokens when memory limits are reached. The approach aims to address the challenges posed by the quadratic cost of self-attention and the growing size of KV caches during long-horizon inference.
  • The implementation of TRIM-KV is significant as it optimizes memory usage in LLMs, ensuring that the most essential tokens are retained for processing. This advancement could lead to more efficient inference processes, potentially reducing computational costs and improving the performance of LLMs in various applications, including natural language processing and machine learning tasks.
  • This development reflects a broader trend in AI research focusing on enhancing the efficiency and effectiveness of LLMs. Strategies such as dynamic token pruning and memory-augmented generation are being explored to tackle similar challenges, indicating a growing recognition of the need for innovative solutions to manage memory constraints and improve reasoning capabilities in AI systems.

GTPO: Stabilizing Group Relative Policy Optimization via Gradient and Entropy Control
PositiveArtificial Intelligence
The introduction of Group-relative Trajectory-based Policy Optimization (GTPO) aims to enhance the stability and performance of Group Relative Policy Optimization (GRPO) in training Large Language Models (LLMs). GTPO addresses critical issues such as conflicting gradient updates on valuable tokens and policy collapse, which have hindered effective model alignment and training processes. By amplifying positive feedback and filtering out high-entropy completions, GTPO seeks to improve convergence and reliability.
Think Before You Prune: Self-Reflective Structured Pruning for Reasoning Language Models
PositiveArtificial Intelligence
Recent research highlights the challenges of pruning reasoning language models (RLMs) like OpenAI's o1 and DeepSeek-R1, which are crucial for multi-step reasoning tasks. The study reveals that traditional pruning methods can severely impair the accuracy and coherence of these models, even at moderate levels of sparsity.
