To date, atmospheric coding platforms have largely been familiar with existing large language models (LLMS) to help write code.
However, writing code is just one of the many different tasks that developers have to perform to build a complete production platform for business quality. Other tasks in the complete software engineering workflow require the use of different tools to help assess, record and maintain code over time. It’s a challenge Windsurfing (formerly Codeium) assumes a series of new frontier AI models that the SWE-1 (Software Engineer 1) mentions as part of the company’s Wave 9 update.
The news comes when Windsurf is said to be taken over in the middle of the AI Leader OpenAi for no less than $ 3 billion. That deal is not yet formally closed and Windsurf is currently not public comments on the deal.
SWE-1 is a family of AI models from Frontier-Class that are specifically designed to speed up the entire software engineering process. In contrast to AI models for general purposes that have been adjusted for coding tasks, the SWE-1 family was built to tackle the entire spectrum of software engineering activities.
The new models are intended to support developers via multiple surfaces, incomplete work states and long -term tasks that characterize the development of software from practice. SWE-1 is immediately available for Windsurf users and marks the access of the company in the development of the frontier model with performance-competitive for established foundation models, but with a focus on workflows for software engineering.
“Our main goal here is to speed up all software engineering by 99%,” Anshul Ramacandran, head of product and strategy at Windsurf, told Venturebeat.
Enterprise developers need more than just coding models
The core innovation behind SWE-1 is the recognition of Windsurf that coding only represents a fraction of what software engineers actually do.
This approach deals with a critical limitation in the current AI coding LLMS. Many different models can be used today to write application code, including the GPT-4.1 from OpenAI, Anthropic Claude 3.7 and Google’s Gemini 2.5 Pro i/O edition.
Windsurf has a modular interface that can make the use of several different models possible. Ramacandran explained that Windsurf users have given the company feedback that existing coding models tend to do well with user guidance, but miss things over time.
This limitation stems from a fundamental difference in task structure. Although generating codes is often a single-shot task, real software engineering navigating by multiple tools includes working with incomplete code and maintaining context in long-term projects.
The SWE-1 family: Specially built for various engineering tasks
Instead of creating a one-size-fits-all solution, Windsurf has developed three specialized models:
- SWE-1: Model in its actual size designed for advanced reasoning and tool use, available for all paid users.
- Swe-1-lite: A smaller but powerful model to replace the existing Cascade base of windsurf, available for all users (both free and paid).
- SWE-1 mini: A lightweight model that is driven passive code stockings on the Windsurf tab, unlimited for all users.
The SWE models were built through an extensive internal training process that was specifically aimed at software engineering tasks. Ramacenran said the company used a new data model with successive steps for training.
Performance bens: How SWE-1 compares
Although SWE-1 is not positioned to replace foundation models of large laboratories, Windsurf claims that it achieves the performance of the front class, specifically for software engineering tasks. The company reports that it performs considerably better than medium -sized foundation models and open weight models.
However, Windsurf ensures that he does not compete these first results.
“Even our benchmark shows that it is not objectively better than all other models,” Ramachandran recognized.
Instead, the aim is to position SWE-1 as the first step in the direction of specially built models that will ultimately exceed general purposes for specific engineering tasks and possible at lower costs.
The Technical Edge: Flow Awareness and Shared Timelines
What makes the approach of windsurf technically distinctive is the implementation of the flow consciousness concept.
The basic idea is that a stream of steps must take place as part of the development of companies. Instead of just writing code for one specific step, flow consciousness is about being aware of the broader context.
Flow Awareness is aimed at creating a shared timeline of actions between people and AI in software development. The core idea is to gradually transfer tasks from person to AI by understanding where AI can help the most effectively.
This approach creates a continuous improvement loop for the models.
“While we continue to improve the models, more of the steps in that shared timeline will be turned from people to AI,” said Ramachanran. “The AI will be able to do more things that people had to do earlier because the AI was not right.”
What this means for technical decision makers
For companies that build or maintain software, SWE-1 represents an important evolution in AI-assisted development. Instead of treating AI coding assistants as simply supplementing automatically, this approach promises to speed up the entire development life cycle.
The potential impact goes further than just writing code faster. The recognition that the development of applications is more involved will help to increase the vibe coding paradigm to apply more to the development of stable Enterprise software.
Although it is still early for SWE-1, this step is important. If and when OpenAi completes the acquisition of Windsurf, the new models can become even more important because they cross each other with the larger model research and development sources that will become available.
Technical leaders must consider how much of their developmental workflow could benefit from AI assistance that goes beyond the generation of codes. Teams that spend a lot of time on code facilities, error detection and managing technical debts can see more substantial benefits of tools such as SWE-1 than those mainly focused on generating new code.
