ZeroEntropy
ZeroEntropy provides production-focused AI models specializing in reranking, embeddings, and custom models to improve retrieval, RAG, and agent workflows. Their offerings include the zerank-2 reranker family and the zembed-1 embedding model, along with fine-tuning and context-compression tools.
The company emphasizes low latency and high accuracy for enterprise systems: lightweight, specialized models and an optimized serving stack aim to reduce p90 latency (example figures shown on the site indicate a reduction from ~500 ms to ~80 ms) and lower end-to-end costs. Deployments include API access, SDKs, VPC/cloud options, and enterprise licensing with SLAs and compliance controls.
ZeroEntropy provides state-of-the-art retrieval for developers building AI products, enabling accurate and relevant information retrieval from any document type via a simple API.
