Tactic: Adaptive Sparse Attention with Clustering and Distribution Fitting for Long-Context LLMs

ICLR 2026poster

Long-context models are essential for many applications but face inefficiencies in loading large KV caches during decoding. Prior methods enforce fixed token budgets for sparse attention, assuming a set number of tokens can approximate full attention. However, these methods overlook variations in th…

Fiddler: CPU-GPU Orchestration for Fast Inference of Mixture-of-Experts Models

ICLR 2025poster

Large Language Models (LLMs) with the Mixture-of-Experts (MoE) architectures have shown promising performance on various tasks. However, due to the huge model sizes, running them in resource-constrained environments where the GPU memory is not abundant is challenging. Some existing systems propose t…

QUEST: Query-Aware Sparsity for Efficient Long-Context LLM Inference

ICML 2024poster

As the demand for long-context large language models (LLMs) increases, models with context windows of up to 128K or 1M tokens are becoming increasingly prevalent. However, long-context LLM inference is challenging since the inference speed decreases significantly as the sequence length grows. This s…
