The acquisition supports Notion’s goal of delivering AI that is fast, affordable, and tailored to specific work for businesses of every size.

## Context

Notion says customers need AI that is powerful, fast, affordable, and built for the specific work people do. It also says frontier AI capabilities have improved only a fraction of the work most businesses and people do every day.

## Approach / What changed

Notion acquired ZeroEntropy and will bring its entire team into the company. ZeroEntropy’s custom kernels, inference stack, model-specialization recipes, and reranker will support Notion’s AI and search goals, with Ghita Houir Alami leading the newly formed Model Research team.

## Takeaways

- ZeroEntropy’s reranker made Notion’s unified search up to 30% faster and reduced reranking latency by 85%.
