Understanding the Physics of Key-Value Cache Compression for LLMs through Attention Dynamics

Samhruth Ananthanarayanan, Ayan Sengupta, Tanmoy Chakraborty

As context windows in LLMs scale to 100K+ tokens, the key-value (KV) cache becomes the dominant memory bottleneck, with recent methods claiming 80-90% savings and minimal benchmark…

HIDE and Seek: Detecting Hallucinations in Language Models via Decoupled Representations

Anwoy Chatterjee, Yash Goel, Tanmoy Chakraborty

Contemporary Language Models (LMs), while impressively fluent, often generate content that is factually incorrect or unfaithful to the input context - a critical issue commonly ref…

Task-conditioned probing of instruction-tuned multimodal LLMs: Region-specific brain alignment patterns under naturalistic stimuli

Subba Reddy Oota, Khushbu Pahwa, Prachi Jindal +5

Recent voxel-wise multimodal brain encoding studies have shown that multimodal large language models (MLLMs) exhibit a higher degree of brain alignment compared to unimodal models.…
