OpenAI did not ultimately buy Windsurf. Reports in April and May 2025 described a proposed acquisition worth about $3 billion, but the transaction had not closed and fell apart by July 11. Google hired Windsurf’s chief executives and selected researchers and licensed some technology; Cognition, the company behind Devin, acquired the remaining Windsurf business on July 14. Windsurf later said access to the latest Claude models had been restored and continues to market support for several competing model providers.
For developers and businesses, the important lesson is that “multi-model” support is not the same as permanent, guaranteed access. Provider contracts, quotas, launch timing, pricing and regional availability can change.
The short answer
- OpenAI’s reported Windsurf acquisition agreement never became a completed purchase.
- Cognition acquired Windsurf’s remaining product, intellectual property, brand and team.
- Google separately hired key Windsurf leaders and researchers and obtained a nonexclusive technology license; it did not acquire the entire company in the reported transaction.
- Anthropic restricted much of Windsurf’s direct Claude capacity during the OpenAI negotiations, then Cognition said access to the latest Claude models returned.
- Windsurf currently markets access to Anthropic, OpenAI, Google Gemini, xAI, DeepSeek and Cognition models, subject to plan, quota, provider and geography limitations.
How the OpenAI deal changed into three separate transactions
| Date | What happened | What it meant |
|---|---|---|
| April–May 2025 | OpenAI was reported to be negotiating to acquire Windsurf for about $3 billion. Bloomberg later reported an agreement, while noting it had not closed. | The headline described a proposed transaction, not completed ownership. Bloomberg Law |
| June 3, 2025 | Windsurf said Anthropic sharply reduced its direct access to Claude 3.x capacity, with less than five days’ notice, and that it lacked direct Claude 4 access at launch. | Claude availability became a commercial and infrastructure issue, not merely an engineering integration. TechCrunch |
| July 11, 2025 | The OpenAI transaction was reported to have fallen apart. Google hired CEO Varun Mohan, co-founder Douglas Chen and selected researchers, and licensed technology. | Talent hiring and licensing were not the same as buying Windsurf. TechCrunch |
| July 14, 2025 | Cognition announced a definitive agreement to acquire Windsurf’s remaining business. | Cognition became the owner of the remaining product and company assets. Cognition |
Reporting linked the collapse to concerns involving Microsoft’s relationship with OpenAI and what Microsoft might gain access to, but neither company announced that explanation as the formal legal reason. Bloomberg Law and The Wall Street Journal were among the outlets reporting on those concerns.
Who owns and operates Windsurf now?
Cognition said it acquired Windsurf’s intellectual property, product, trademark, brand, business and employees who were not hired by Google. It said the IDE would continue operating in the near term while its capabilities were integrated into Cognition products over time. Cognition also claimed Windsurf had $82 million in annual recurring revenue, more than 350 enterprise customers and hundreds of thousands of daily active users; those are Cognition’s figures, not independently audited numbers.

#1 Best Overall
Google’s separate license means it can use certain Windsurf technology without owning the remaining Windsurf business. That distinction matters when assessing control, billing, product decisions and future model access.
What happened to Claude support?
During the proposed OpenAI transaction
Windsurf said Anthropic cut nearly all of its first-party capacity for certain Claude 3.x models and gave it less than five days’ notice. Windsurf said it had to rely on third-party inference providers and warned that users could see availability problems. It also said it did not receive direct Claude 4 access at launch. Users could supply their own Anthropic API keys, but that route can be more complex and can shift usage costs to the customer. TechCrunch
Rank #2
Anthropic said it was prioritizing sustainable partnerships. The episode also reflected competitive incentives: model providers increasingly offer their own coding products, so an IDE that depends on them may be both a customer and a potential rival.
After Cognition acquired Windsurf
Cognition stated that Windsurf had “full access to the latest Claude models” again. That indicates the immediate access crisis was resolved after Windsurf was no longer moving toward OpenAI ownership. It does not guarantee that every Claude model is available to every account, plan or country. The current model selector and documentation are the practical authority for an individual user.

Does Windsurf still support OpenAI, Gemini and other models?
Windsurf’s current marketing names Anthropic, OpenAI, Google Gemini, xAI, DeepSeek and Cognition models. Windsurf’s provider page The list is a product-positioning claim, not a promise that every model is continuously available through one access method.
| Access question | Why it matters |
|---|---|
| Managed or native access | Windsurf supplies the model route and may include usage in a subscription or credits. |
| BYOK (bring your own key) | You provide a provider API key; billing, limits and data terms may then come from that provider. |
| Plan and quota | A model may be limited to paid tiers, monthly credits, rate limits or usage multipliers. |
| Launch timing | A model can appear later through a third-party route even when it is available directly from its creator. |
| Geography and account | Documentation can list a model that is not enabled for a particular region, workspace or product version. |
Cognition’s data-processing addendum lists OpenAI, Anthropic, Google/Vertex, xAI, AWS/Bedrock and other providers for Windsurf-related processing when enabled. Teams should therefore review routing and retention terms, not rely only on a provider list. Cognition Data Processing Addendum

Model neutrality is valuable but conditional
Different models can be better for code generation, long-context analysis, editing, debugging or agentic tasks. An IDE that lets users switch providers can reduce dependence on one model and preserve workflows when a model underperforms. The Anthropic episode shows that neutrality depends on commercial agreements and inference capacity as much as on software architecture.
Check the real cost, not just the subscription
Windsurf’s upgrade page showed a free tier and a $20-per-month Pro tier when crawled in 2026, alongside usage and model-access claims. Treat that as a dated signal: prices, credits and overage rules can change. Windsurf pricing Premium models may consume credits faster, require a higher plan or incur separate BYOK API charges.

Use a continuity checklist before standardizing
- Open the live model selector in your account and confirm the exact Claude, OpenAI, Gemini or other model you need.
- Record whether access is managed by Windsurf, BYOK or a third-party route.
- Read quota, credit, rate-limit and overage rules for your plan.
- Test switching to a second provider without changing the editor or losing project instructions.
- Review the current DPA, retention policy, administrator controls and subprocessors before sending proprietary code.
- Export rules, prompts, settings and project configuration so a provider or product change does not strand your workflow.
How Windsurf compares with other model strategies
| Approach | Best for | Main trade-off |
|---|---|---|
| Windsurf | An integrated IDE with several advertised model providers. | Availability, quotas and routing can change with provider agreements. |
| Cursor | Users wanting a competing AI-native editor with multiple model options. | Provider and usage terms still need checking on the current plan. |
| GitHub Copilot | Organizations standardized on GitHub and enterprise administration. | Less focused on broad provider-neutral routing. |
| Claude Code or OpenAI Codex | Teams committed to one provider’s first-party coding workflow. | Less model diversity in one tool. |
| Gemini Code Assist | Google Cloud and Gemini-centered teams. | Not a neutral multi-provider environment. |
| Continue or Cline | Technical users who want BYOK and customizable routing. | More setup, billing and operational responsibility. |
Verdict
The “OpenAI is buying Windsurf” headline is no longer an accurate description of ownership. The reported $3 billion deal did not close; Google took a separate talent-and-licensing path, and Cognition acquired the remaining Windsurf business. Cognition said Claude access was restored, while Windsurf continues to advertise support for multiple rival providers.
That makes Windsurf’s model-neutral pitch more credible than the original headline suggested, but not permanent. Anyone committing a production codebase or enterprise budget should verify the live model selector, access method, quotas, data terms and portability before treating multi-provider support as a guarantee.
