Windsurf has released the latest Wave 13 update for its popular AI code editor, focusing on enhancing multi-agent workflows, performance availability, and endpoint reliability. The core highlight of this update is that the new SWE-1.5 model is officially online and open to all users by default, along with Git worktree support, multi-session parallel views, and an improved Cascade terminal experience.

According to reports, SWE-1.5 has now become the default model of Windsurf, has complete inference capabilities, and maintains high performance in the SWE-Bench-Pro benchmark test, while still ensuring a responsive experience at normal speeds. The model will be available for free to users for the next three months, after being tested under the codename "Penguin Alpha." In order to help users better manage context resources, Wave 13 also adds a context window indicator to facilitate real-time monitoring of context usage and predict upper limits, complementing Cascade's automatic summary function.

In terms of development process, Wave 13 introduces Git worktree support for Cascade, allowing users to open multiple sessions on different branches in the same code repository without causing file conflicts. Users can also view and operate multiple Cascade sessions side by side in columns or multiple tabs in the same window, thereby improving multi-tasking and multi-branch collaboration efficiency. In addition, users can now set Cascade Hooks at specific stages of the agent lifecycle, such as triggering after each message, allowing for more granular automated workflow control.

Terminal experience is also one of the focuses of this update. Wave 13 introduces a new Cascade terminal that is in beta, using an interactive zsh environment to improve overall reliability, and supports .zshrc configuration variables and interactive prompts for better compatibility with complex shell configuration scenarios. The terminal is currently open to macOS users on a "voluntary basis" basis. At the same time, the new version also improves the color matching and style presentation in the terminal to ensure that the original colors and formats can be retained in Cascade.

For enterprise customers, Wave 13 introduces system-level rules and workflow support issued through MDM policies to facilitate unified management and compliance control. In addition, the update improves diff zone behavior, introduces more configurable scrolling settings, and makes several stability enhancements to the Model Context Protocol (MCP) implementation.
