Factory, a startup founded in 2023 with the aim of eliminating traditional software development bottlenecks, is leveraging reasoning models from OpenAI to streamline and optimise the creation and maintenance of software.
The Factory Platform integrates OpenAI’s o1, o3-mini, and GPT-4o models directly into its workflows, creating a development environment that transcends simple code generation. Instead, it focuses on understanding, retrieving, and reasoning through complex systems.
This approach has reportedly yielded impressive results, including:
- 2–4x faster feature development cycles.
- 60% reduction in context switching time.
- 10+ additional hours per week per developer across the software development lifecycle.
“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, Co-Founder and CTO of Factory.
Tackling software development inefficiencies with OpenAI
Traditionally, software development has been hampered by manual research, fragmented knowledge, and protracted iteration cycles. Engineers often spend considerable time understanding dependencies and verifying system accuracy, rather than focusing solely on coding.
Before integrating OpenAI’s reasoning models, Factory relied on a combination of in-house solutions and conventional tools. However, they encountered several limitations:
- Planning bottlenecks: The absence of automated methods to structure and coordinate development steps.
- Code editing inefficiencies: Existing AI completions lacked the required speed and accuracy for large-scale development.
- Ineffective knowledge retrieval: Standard search tools failed to efficiently surface relevant code snippets or documentation.
Factory recognised an opportunity to transform this landscape by developing a system where AI extends beyond code suggestions to comprehend and reason about the entire software development process. They have established a close collaboration with OpenAI to integrate cutting-edge models at every stage of the development lifecycle.
Optimising the software development lifecycle
Factory strategically deploys OpenAI’s models across various stages of the software development lifecycle, selecting specific models based on their reasoning capabilities, speed, and accuracy requirements.
- Exploration: Utilising OpenAI o3-mini for rapid code understanding and documentation searches, leveraging its fast response times.
- Prioritisation: Employing OpenAI o3-mini for bug triage and feature analysis, balancing reasoning capability and speed.
- Planning: Leveraging OpenAI o1 for complex architectural decisions and system design, capitalising on its high reasoning capabilities.
- Execution: Integrating OpenAI o1, o3-mini, and GPT-4o for code generation, editing, and reviews, with predicted outputs reducing latency by 50% for real-time coding assistance.
“We’ve found that giving developers flexibility to choose the right model for their specific task is crucial,” says Reyes. “For quick code reviews, o3-mini provides almost identical quality to larger models but at significantly faster speeds, while complex architectural planning benefits from o1’s deeper reasoning capabilities.”
Factory is also exploring reinforcement fine-tuning of o3-mini for code reranking and auto-injecting lightweight guidance to enhance model compliance, thereby improving precision in production-grade AI development.
“OpenAI’s reasoning models allow us to move beyond just code generation. We’re building an agentic development environment where AI can deeply understand, retrieve, and act on engineering knowledge,” explains Reyes.
Towards autonomous software development
Factory’s integration of OpenAI’s capabilities enables developers to reason through engineering challenges, retrieve critical knowledge, and optimise workflows. Its context-first architecture dynamically extracts insights from codebases, documentation, and issue tracking systems, minimising context-switching and cognitive overhead.
Instead of navigating multiple tools, developers can access everything they need in a single platform, allowing them to focus on high-impact tasks.
Factory’s future focus is on achieving greater autonomy in AI-powered development. By integrating native tools across source control, project management, team communication, error monitoring, and continuous delivery pipelines, combined with reasoning models, they are developing AI systems capable of proactively planning, executing, and refining engineering tasks.
“The software of the future will be built by humans and AI, together, in one platform. With OpenAI’s reasoning models, we’re enabling developers to focus on higher-leverage work while AI handles the complexity,” concludes Matan Grinberg, Co-Founder and CEO of Factory.
