Vibe-coding startup Windsurf launches in-house AI models
On Thursday, Windsurf, a startup that develops popular AI tools for software engineers, announced the launch of its first family of AI software engineering models, or SWE-1 for short. The startup says it trained its new family of AI models — SWE-1, SWE-1-lite, and SWE-1-mini — to be optimized for the "entire software engineering process," not just coding. The launch of Windsurf's in-house AI models may come as a shock to some, given that OpenAI has reportedly closed a $3 billion deal to acquire Windsurf. However, this model launch suggests Windsurf is trying to expand beyond just developing applications to also developing the models that power them. According to Windsurf, SWE-1, the largest and most capable AI model of the bunch, performs competitively with Claude 3.5 Sonnet, GPT-4.1, and Gemini 2.5 Pro on internal programming benchmarks. However, SWE-1 appears to fall short of frontier AI models, such as Claude 3.7 Sonnet, on software engineering tasks. Windsurf says its SWE-1-lite and SWE-1-mini models will be available for all users on its platform, free or paid. Meanwhile, SWE-1 will only be available to paid users. Windsurf did not immediately announce pricing for its SWE-1 models but claims it's cheaper to serve than Claude 3.5 Sonnet. Windsurf is best known for tools that allow software engineers to write and edit code through conversations with an AI chatbot, a practice known as "vibe coding." Other popular vibe-coding startups include Cursor, the largest in the space, as well as Lovable. Most of these startups, including Windsurf, have traditionally relied on AI models from OpenAI, Anthropic, and Google to power their applications. In a video announcing the SWE models, comments made by Windsurf's Head of Research, Nicholas Moy, underscore Windsurf's newest efforts to differentiate its approach. "Today's frontier models are optimized for coding, and they've made massive strides over the last couple of years," says Moy. "But they're not enough for us … Coding is not software engineering." Windsurf notes in a blog post that while other models are good at writing code, they struggle to work between multiple surfaces — as programmers often do — such as terminals, IDEs, and the internet. The startup says SWE-1 was trained using a new data model and a "training recipe that encapsulates incomplete states, long-running tasks, and multiple surfaces." The startup describes SWE-1 as its "initial proof of concept," suggesting it may release more AI models in the future.

Windsurf Launches SWE-1: A Frontier AI Model Family Built for the Full Software Engineering Lifecycle
MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)-- Windsurf, the company transforming how software is built, today announced the launch of SWE-1, its first family of proprietary AI models designed to accelerate the entire software engineering process, not just code generation. The SWE-1 family includes three models optimized for different workflows and user tiers, and marks Windsurf's entry into frontier model development with performance competitive to foundational models for software-relevant tasks. 'Writing code is only a fraction of what engineers do,' said Varun Mohan, CEO and co-founder of Windsurf. 'To truly accelerate software development by 99%, we had to move beyond 'coding-capable' models and build software engineering-native models. SWE-1 is our first step in that direction, building a foundation for the future state.' Meet the SWE-1 Family: SWE-1: Windsurf's full-size model, built for advanced reasoning and tool use. Available for unlimited use to all paid users. SWE-1-lite: A smaller but powerful model that replaces Cascade Base, now available for unlimited use to all users, free and paid. SWE-1-mini: A lightweight model powering Windsurf Tab, designed for fast, passive code prediction, now unlimited to all free and paid users. Powered by Flow Awareness SWE-1 was made possible through Windsurf's core design principle: flow awareness, the ability for humans and AI to operate on a shared timeline. This deep integration between the Windsurf Editor and its models allows seamless, context-aware collaboration and sets the foundation for continuously improving model performance at scale. 'Flow awareness lets us see exactly where models succeed or fail, down to the individual decision point. That feedback loop is our competitive edge,' said Anshul Ramachandran, Founding Team. With a continuous stream of user feedback, Windsurf has been steadily building the richest representation of a shared timeline for software engineering work. SWE-1 is the initial proof of concept for understanding a true end-to-end timeline. What's next While SWE-1 represents Windsurf's first venture into frontier model development, it won't be the last, and it is a testament to what can be achieved with a small engineering team and a limited scope of compute. The company plans to invest aggressively in SWE models and intends on rapidly expanding its machine learning research team going forward. Developers can begin using the SWE-1 model family with the Windsurf Editor by visiting today. About Windsurf: Windsurf is a generative AI-powered software development platform helping engineers move faster, reduce technical debt, and build with greater confidence. With code-native models and flow-aware tools, Windsurf integrates seamlessly into existing workflows to enable higher-quality engineering at scale.
