Relace
This is a Model Atlas entity, not a ranked standalone lab. A plausible organization withheld from the directory until independent evidence clears the publication gate.
Relace is an important example of the model stack becoming specialized around agent operations such as context retrieval and patch application.
Profile
Overview
Relace is a San Francisco company founded by Preston Zhou and Eitan Borgnia. It develops specialized models and infrastructure for coding agents, including systems for retrieving codebase context, applying generated edits, and operating repositories.
The company emerged from Y Combinator's Winter 2023 batch. Its Apply and Search model lines target narrow stages of the coding-agent loop rather than general chat, and its infrastructure is used by software-generation products including Lovable and Figma.
Notable contributions
- 01Fast code-apply modelsRelace trained small models to merge generated edits into existing files at more than 10,000 tokens per second.
- 02Agent-native repositoriesRelace Repos adapts source control and retrieval to the high-frequency operations of coding agents.
