T2D: Target-to-Draft Model Pruning & Adaptation for Efficient Speculative Decoding

The paper introduces T2D, a framework that prunes and adapts a target large language model into a draft model optimized for both inference latency and alignment with the target model’s outputs. By formulating draft model design as an optimization problem, T2D achieves up to 92% pruning while maintaining high speculative decoding performance across multiple target model families and domains. The resulting draft models can also be integrated with other speculative decoding techniques to yield additional gains.

Guided Prompt Evolution for Vision-Language Models Adaptation

The paper introduces EvoPrompt, a framework for adapting vision‑language models to new tasks with limited data while preventing catastrophic forgetting. EvoPrompt uses a Modality‑Shared Prompt Projector to create hierarchical prompts and an evolutionary training strategy that separates low‑rank updates into directional and magnitude components, preserving learned semantic directions. Experiments show that EvoPrompt achieves state‑of‑the‑art few‑shot performance while maintaining the original zero‑shot capabilities of the pre‑trained models.

SKIM: Pruning Large Language Model Agents via Selective Knowledge Informed Masking

SKIM (Selective Knowledge-Informed Masking) is a pruning and distillation framework designed for large language model agents that operate under structured generation, where grammar constraints limit output to valid tokens. The method partitions token positions into context, decision, and format categories, using category-aware pruning to preserve parameters most relevant to decision positions and an on-policy distillation objective that aligns student and teacher on valid tokens with category-aware feature matching. Evaluations on tool-calling benchmarks and multi-step agent loops across various model scales and sparsity levels show that SKIM consistently outperforms baseline compression methods, especially in high-sparsity regimes where conventional techniques falter.
