Overview

• Windsurf has introduced its SWE-1, SWE-1-lite, and SWE-1-mini models, designed to optimize the entire software engineering workflow, not just coding tasks.
• The SWE-1 models are now integrated into Windsurf's platform, with SWE-1-lite and SWE-1-mini available for free, while the full SWE-1 model is gated for paid users.
• Internal benchmarks show SWE-1 performs competitively with leading models like Claude 3.5 Sonnet and GPT-4.1, particularly in scenarios tailored to Windsurf’s platform.
• Blind A/B tests revealed SWE-1 drives higher user engagement, retention, and trust in outputs compared to Windsurf’s previous Cascade Base model.
• Despite launching its own models, Windsurf remains model-agnostic and will continue to offer third-party AI models from providers such as OpenAI and Anthropic.
