SWE-1.5 Free
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.

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.
