On Thu, May 15, 2025, Windsurf introduced the SWE-1 family, a series of AI models designed to enhance the entire software engineering process. This marks a significant development in AI-assisted software engineering, expanding beyond code generation.
The SWE-1 family addresses a critical limitation in AI development tools by encompassing the entire software engineering workflow. It includes three models:
SWE-1: The flagship model, offering tool-call reasoning capabilities comparable to leading models while being cost-efficient. Temporarily available to paid users at zero credits per prompt. SWE-1-lite: A mid-sized model replacing the Cascade Base model, providing improved quality and unlimited use for all users. SWE-1-mini: A small, ultra-fast model supporting Windsurf Tab's passive experience for all users.
Windsurf's models incorporate "flow awareness," allowing them to operate within a shared development timeline. This capability facilitates seamless collaboration between humans and AI, enabling models to understand incomplete work states and adapt to human contributions.
SWE-1 has demonstrated competitive performance against major AI labs' models, excelling in benchmarks such as:

Conversational SWE Task Benchmark: Evaluates a model's ability to respond to user queries during an ongoing session with an unfinished task. End-to-End SWE Task Benchmark: Assesses a model's capability to solve problems independently from start to finish.
In real-world tests, SWE-1 has shown strong performance in metrics like "Daily Lines Contributed per User" and "Cascade Contribution Rate."
The SWE-1 models are particularly beneficial for DevOps professionals, facilitating work across terminals, text editors, and browsers. The models can:
Incorporate terminal outputs and understand errors Transition between text editing and debugging Maintain awareness of terminal commands and IDE actions Process user feedback and testing results
These capabilities streamline the integration between development and operations phases.
Windsurf plans to continue enhancing the SWE-1 models, aiming to exceed the performance of models from leading research labs. This focus on comprehensive engineering processes represents a promising advancement for AI integration in software development.
The "flow-aware" approach offers a model for human-AI collaboration that aligns with the iterative nature of modern software engineering.
