To this point, vibe coding platforms have largely relied on present giant language fashions (LLMs) to assist write code.
Nonetheless, writing code is just one of many various duties builders must carry out to construct a full enterprise-grade manufacturing platform. Different duties within the full software program engineering workflow require utilizing totally different instruments to assist assessment, commit and keep code over time. It’s a problem Windsurf (previously Codeium) is taking over with a sequence of latest frontier AI fashions it calls SWE-1 (software program engineer 1) as a part of the corporate’s Wave 9 replace.
SWE-1 is a household of frontier-class AI fashions particularly designed to speed up your entire software program engineering course of. Not like general-purpose AI fashions which were tailored for coding duties, the SWE-1 household was constructed to deal with the complete spectrum of software program engineering actions.
The brand new fashions intention to help builders by means of a number of surfaces, incomplete work states and long-running duties that characterize real-world software program growth. Out there instantly to Windsurf customers, SWE-1 marks the corporate’s entry into frontier mannequin growth with efficiency aggressive to established basis fashions, however with a deal with software program engineering workflows.
“Our main goal here is to accelerate all software engineering by 99%,” Anshul Ramachandran, head of product and technique at Windsurf, informed VentureBeat.
Enterprise builders want extra than simply coding-capable fashions
The core innovation behind SWE-1 is Windsurf’s recognition that coding represents solely a fraction of what software program engineers really do.
This method addresses a crucial limitation in present AI coding LLMs. Many various fashions can be utilized at present to jot down software code, together with OpenAI’s GPT-4.1, Anthropic Claude 3.7 and Google’s Gemini 2.5 Professional I/O version.
Windsurf has a modular interface that may allow use of a number of totally different fashions. Ramachandran defined that Windsurf customers have given the corporate suggestions that present coding fashions are inclined to do nicely with consumer steering, however over time are inclined to miss issues.
This limitation stems from a basic distinction in process construction. Whereas code technology is commonly a single-shot process, actual software program engineering entails navigating a number of instruments, working with incomplete code and sustaining context throughout long-running initiatives.
The SWE-1 household: Goal-built for various engineering duties
Moderately than making a one-size-fits-all resolution, Windsurf has developed three specialised fashions:
SWE-1: Full-size mannequin designed for superior reasoning and power use, accessible to all paid customers.
SWE-1-lite: A smaller however highly effective mannequin changing Windsurf’s present Cascade Base, accessible to all customers (each free and paid).
SWE-1-mini: A light-weight mannequin powering passive code predictions in Windsurf Tab, limitless for all customers.
The SWE fashions have been constructed by means of an intensive in-house coaching course of targeted particularly on software program engineering duties. Ramachandran mentioned that the corporate used a brand new knowledge mannequin with sequential steps for coaching.
Efficiency benchmarks: How SWE-1 compares
Whereas SWE-1 isn’t positioned to switch basis fashions from main labs, Windsurf claims it achieves frontier-class efficiency particularly for software program engineering duties. The corporate stories that it considerably outperforms mid-sized basis fashions and open-weight fashions.
Nonetheless, Windsurf is cautious to not oversell these preliminary outcomes.
“Even our benchmark shows it’s not objectively better than all the other models,” Ramachandran acknowledged.
As a substitute, the aim is to place SWE-1 as step one towards purpose-built fashions that can finally surpass general-purpose ones for particular engineering duties — and doubtlessly at a decrease price.
The technical edge: Circulate consciousness and shared timelines
What makes Windsurf’s method technically distinctive is its implementation of the movement consciousness idea.
The essential concept is {that a} movement of steps must occur as a part of enterprise growth. Moderately than simply writing code for one particular step, movement consciousness is about being conscious of the broader context.
Circulate consciousness is centered on making a shared timeline of actions between people and AI in software program growth. The core concept is to progressively switch duties from human to AI by understanding the place AI can most successfully help.
This method creates a steady enchancment loop for the fashions.
“As we continue to improve the models, more of the steps in that shared timeline will be flipped from human to AI,” mentioned Ramachandran. “The AI will be able to do more things that the human had to do before because the AI wasn’t right.”
What this implies for technical decision-makers
For enterprises constructing or sustaining software program, SWE-1 represents an vital evolution in AI-assisted growth. Moderately than treating AI coding assistants as merely autocomplete instruments, this method guarantees to speed up your entire growth lifecycle.
The potential impression extends past simply writing code extra rapidly. The popularity that software growth is extra concerned will assist mature the vibe coding paradigm to be extra relevant for steady enterprise software program growth.
Whereas it’s nonetheless early days for SWE-1, this transfer is vital. If and when OpenAI completes the acquisition of Windsurf, the brand new fashions may change into much more vital as they intersect with the bigger mannequin analysis and growth sources that can change into accessible.
Technical leaders ought to take into account how a lot of their growth workflow may gain advantage from AI help past mere code technology. Groups spending important time on code evaluations, debugging and managing technical debt may see extra substantial advantages from instruments like SWE-1 than these primarily targeted on producing new code.
