Bug Fixes and Improvements
- Improvements to GPT-5.2-Codex harness
- Admins can now manage Windsurf restrictions via Windows Group Policy

Adds support for GPT-5.2-Codex with four reasoning efforts (low, medium, high, and xhigh). GPT-5.2-Codex is OpenAI's latest model designed for agentic coding. It excels at working in large codebases over long sessions. For most tasks, we recommend using the medium reasoning effort.
Gemini 3 Flash is now available for all users. This model combines Gemini 3 Pro-grade reasoning with Flash-level speed and efficiency, making it ideal for agentic workflows and coding tasks.
Wave 13 brings first-class support for parallel, multi-agent sessions in Windsurf, along with Git worktrees, side-by-side Cascade panes, and a dedicated terminal profile for more reliable agent execution.

Our near-frontier model, SWE-1.5, is now available for free to all users for the next 3 months. SWE-1.5 Free has the full intelligence of SWE-1.5, with the same coding performance on SWE-Bench-Pro, but delivered at standard throughput speeds. The original variant of SWE-1.5 hosted on Cerebras will continue to be available for paid users. SWE-1.5 Free will replace SWE-1 as the default model in Windsurf starting today.
Windsurf now supports Git worktrees, letting you spawn multiple Cascade sessions in the same repository without conflicts. Git worktrees check out different branches into separate directories while sharing the same Git history.
You can already run multiple Cascade sessions in Windsurf at the same time. Now, you can view and interact with them in separate panes and tabs within the same window. This lets you monitor progress and compare outputs of sessions side-by-side, or even turn Windsurf into a big Cascade dashboard.
Windsurf introduces a new approach for letting agents execute terminal commands. Instead of your default shell, Cascade will now run commands in a dedicated zsh shell specifically configured for reliability. The Cascade Dedicated Terminal can use the environment variables you set in your .zshrc configuration and is interactive, which means you can answer any prompts from shell scripts without having to break your flow. This should improve the reliability and speed of shell commands, especially for users with complicated prompts (e.g., powerlevel10k).
In this version, the Cascade Dedicated Terminal will be opt-in for Windsurf Stable on macOS. If you are experiencing issues with the older legacy terminal, we recommend switching to the new terminal early. We expect to make this feature the default in the future, while maintaining the legacy terminal extension for backwards compatibility purposes. You can opt-in in the Windsurf User Settings -> Disable Windsurf Legacy Terminal Profile.
When a model's context window grows too long, earlier context can be dropped without warning and performance can degrade. Cascade already extends the window by occasionally summarizing messages and clearing history. This release adds a visual indicator to see how much of your context window is currently in use, helping you anticipate limits and decide when to start a new session.
Execute custom commands at key points during Cascade's workflow, including on model response for auditing purposes.
Enterprises can deploy rules and workflows via MDM policies, allowing organizations to place rules and workflows files on users' machines.
Added a new "Promo" label to LLM models that are newly available or have special discount pricing

GPT-5.2 is now available in Windsurf. This model will be available for 0x credits in Windsurf (to paid users) for a limited time.
GPT-5.2 represents the biggest leap for GPT models in agentic coding since GPT-5 and is a SOTA coding model in its price range. The version bump undersells the jump in intelligence. We`re excited to make it the default across Windsurf and several core Devin workloads. - Jeff Wang, CEO of Windsurf

Introducing GPT-5.1-Codex Max in three reasoning tiers (Low, Medium, High). Low variant available at no cost to paid users for a limited time.

You can now use Claude Opus 4.5 in Windsurf!
Opus 4.5 is the most capable model in Windsurf yet and is now available at Sonnet pricing for a limited time (2x credits compared to 20x for Opus 4.1).
This model is available to all paid Windsurf subscribers.
Note: The Autocomplete setting has been removed as it was a legacy option that had no effect. Windsurf's Tab autocomplete feature is powered by Supercomplete.
.codeiumignore and .gitignore for Fast Context.You can now use Windsurf's AI agent with worktrees to explore and modify code across multiple branches simultaneously.

GPT-5.1 and GPT-5.1-Codex are now available in Windsurf. GPT-5.1 will become the default model in Windsurf for one week, and paid users get free access during this period.
GPT-5.1 and GPT-5.1-Codex deliver a solid upgrade from GPT-5 for agentic coding workflows. They're noticeably better at understanding what you're asking for and working with you to get it done. The new variable thinking feature dynamically adjusts reasoning depth—providing quick responses for simple tasks and more thoughtful analysis when complexity demands it.
Option/Alt+Cmd+L when in an editor to attach the current file to Cascademcp_config.json is modified, only the affected MCP server instance is initialized/refreshed - no other instances are refreshedEnhanced the SWE-1.5 + Claude Sonnet 4.5 mode with improved performance and reliability for better coding assistance.
Codemaps now include powerful new capabilities:
Improved Cascade summarization to better handle longer conversations. Previously, summaries could be too aggressive and drop important context. Now maintains better continuity across long sessions with multiple file changes and user messages.
You can now enable beta Sonnet 4.5 planning when using SWE 1.5. To enable, select SWE 1.5 first, then select the Sonnet 4.5 addon.
New beta plan mode (type /plan in the Cascade chat input to activate it).
Expanded Codemaps:
You can now try a new stealth model in Windsurf: Falcon Alpha. Falcon Alpha is a powerful agentic model designed for speed. We're excited to hear what you build with it!


GPT-5-Codex is now available for free (0x credits) for a limited time for paid users!
Free users can use GPT-5-Codex as well for 0.5x credits.
