AdapShot: Adaptive Many-Shot In-Context Learning with Semantic-Aware KV Cache Reuse

arXiv:2605.03644v2 Announce Type: replace Abstract: Many-Shot In-Context Learning (ICL) has emerged as a promising paradigm, leveraging extensive examples to unlock the reasoning potential of Large Language Models (LLMs). However, existing methods typically rely on a predetermined, fixed number of shots. This static approach often fails to adapt to the varying difficulty of different queries, leading to either insufficient context or interference from noise. Furthermore, the prohibitive computational and memory costs of long contexts severely limit Many-Shot's feasibility. To address the above

Why this matters
Why now

Development of more efficient in-context learning methods is critical as LLMs scale and their computational demands become a bottleneck for wider application.

Why it’s important

This paper addresses a fundamental constraint in the scalability and practical application of large language models, potentially making powerful ICL more accessible and cost-effective.

What changes

The ability to run many-shot ICL more efficiently by adaptively selecting examples and reusing KV cache significantly reduces computational cost and memory, enabling broader deployment.
