Windsurf Launches SWE-1.6 With Industry-Leading 950 Tok/s Speed and Free 3-Month Access
Summary
Windsurf launches SWE-1.6, a blazing-fast AI coding model hitting 950 tokens per second, now freely available for three months, featuring smarter task execution with reduced overthinking and faster parallel tool calls powered by Fireworks and Cerebras.
Key Points
- SWE-1.6 is now generally available in Windsurf, offering industry-leading speed of up to 950 tok/s and a free tier for the next 3 months, built on top of last month's SWE-1.6 Preview release.
- The new model is post-trained from scratch to dramatically improve 'model UX' by reducing overthinking, looping behavior, and unnecessary terminal use, while increasing parallel tool calls for faster and smoother task completion.
- A length penalty introduced during training keeps response trajectories efficient without sacrificing intelligence, and partnerships with Fireworks and Cerebras power the free and premium speed tiers respectively.
