SnapStream: Efficient Long Sequence Decoding on Dataflow Accelerators

Jonathan Li, Nasim Farahini, Evgenii Iuliugin +19

The proliferation of 100B+ parameter Large Language Models (LLMs) with 100k+ context length support have resulted in increasing demands for on-chip memory to support large KV cache…

Agentic Context Engineering: Evolving Contexts for Self-Improving Language Models

Qizheng Zhang, Changran Hu, Shubhangi Upasani +10

Large language model (LLM) applications such as agents and domain-specific reasoning increasingly rely on context adaptation: modifying inputs with instructions, strategies, or evi…

Test-Time Adaptation via Many-Shot Prompting: Benefits, Limits, and Pitfalls

Shubhangi Upasani, Chen Wu, Jay Rainton +4

Test-time adaptation enables large language models (LLMs) to modify their behavior at inference without updating model parameters. A common approach is many-shot prompting, where l…

Cross-Family Speculative Prefill: Training-Free Long-Context Compression with Small Draft Models

Shubhangi Upasani, Ravi Shanker Raju, Bo Li +5

Prompt length is a major bottleneck in agentic large language model (LLM) workloads, where repeated inference steps and multi-call loops incur substantial prefill cost. Recent work…

Adaptive Multi-Objective Tiered Storage Configuration for KV Cache in LLM Service

Xianzhe Zheng, Zhengheng Wang, Ruiyan Ma +17

The memory-for-computation paradigm of KV caching is essential for accelerating large language model (LLM) inference service, but limited GPU high-bandwidth memory (HBM) capacity m…

LLMs Know What to Drop: Self-Attention Guided KV Cache Eviction for Efficient Long-Context Inference

Guangtao Wang, Shubhangi Upasani, Chen Wu +5

Efficient long-context inference is critical as large language models (LLMs) adopt context windows of ranging from 128K to 1M tokens. However, the growing key-value (KV) cache and…
