Vibe-coding startup Windsurf launches in-house AI models | TechCrunch
Windsurf has launched its own AI models named SWE-1, SWE-1-lite, and SWE-1-mini, built for the full software engineering process, not just coding.. SWE-1 will be available only to paid users, while SWE-1-lite and SWE-1-mini will be accessible to both free and paid users.. SWE-1 performs comparably to GPT-4.1 and Claude 3.5 Sonnet but falls behind newer models like Claude 3.7.. Windsurf is shifting from relying on third-party AI models to building its own, expanding beyond just application development..
