“The flexibility of offering o1 and o3‑mini for a range of reasoning tasks has helped us win business from customers seeking a software development tool that allows seamless switching between models with varying reasoning capabilities,” says Eno Reyes, Factory’s co-founder and CTO.

Software development has often been constrained by manual research, fragmented knowledge, and slow iteration cycles. Engineers don’t just write code; they spend hours understanding dependencies and verifying system accuracy.

Before OpenAI’s family of reasoning models, Factory relied on a mix of in-house solutions and traditional tooling, but they ran into key limitations:

Factory saw an opportunity to change this by building a system where AI goes beyond suggesting code to understanding and reasoning about the entire software development process. They work closely with OpenAI to integrate cutting-edge models at every stage of the software development lifecycle.
