👋 Hey Hunters!

Just dropped something big — Windsurf Wave 9 with the new SWE-1 models!

These AI models are built to help with real engineering work — not just writing code. You’ve got three options:

✅ SWE-1: Super powerful for heavy, complex tasks

✅ SWE-1 Lite: Lighter and faster for everyday dev work

✅ SWE-1 Mini: Blazing fast for when speed really matters

They’re all built into the Windsurf Editor, making things like debugging and code generation way easier. It’s like having an extra set of smart hands helping out.

Excited to see what you build with it! 🚀🛠️

"Wave 9" isn't the product name — it's SWE-1.

Hi @saaswarrior @varunkmohan @dpchen

I'm Abdelhy Khaled, team leader of offensive security researchers focused on web application security.

During a non-intrusive security review of your public-facing infrastructure, we noticed indicators of potential vulnerabilities that could put your users or data at risk if left unresolved.

We're reaching out to offer responsible disclosure and — if you're interested — a professional penetration testing engagement to help uncover and fix these issues proactively.

Let me know if you'd like us to securely share our initial findings or discuss how we can help enhance your platform’s security posture

thanks

I haven't seen any model designed specifically for engineering. Sounds very promising. Is it live yet? I'd like to try it out.

Impressive launch. Congratulations. We recently launched Mukh.1, a no-code platform for AI workflows and agents. Check it out.

This tool looks super powerful! I’m curious, can these three SWE-1 models be seamlessly switched during use? For example, if I’m working on a complex task with SWE-1 but need to quickly handle a simpler one, can I directly switch to SWE-1 Mini?
