Introduction

ZeroEntropy develops state-of-the-art AI models for information retrieval — including rerankers, embedders, and end-to-end retrieval pipelines.
Our technology powers intelligent search systems that can index, search, and retrieve documents with exceptional precision.

​
What is Agentic Retrieval?

Agentic Retrieval refers to a retrieval system that actively determines the optimal strategy to find information based on the context of a query.
Unlike traditional systems, it mimics human reasoning — selecting and combining retrieval techniques dynamically, and improving through feedback and learning over time.

​
