At Codeium, we&#x27;ve been building AI-powered extensions for a while (we first launched our VSCode extension with autocomplete a little over 2 years ago!), but we&#x27;ve always thought there would come a day where we would hit the limits of what could be achieved within existing IDEs, so we decided to build our own: Windsurf (yes, it&#x27;s yet another VSCode fork :)<p>We&#x27;ve stuffed a lot of cool features into Windsurf—a super fast autocomplete model, an inline diff generation experience that feels truly native, but we&#x27;re most proud of Cascade, which is an evolution of the sidebar chat experience that many other extensions have. Cascade can perform deep reasoning on your existing codebase, access a vast array of tools that allow it to run terminal commands and find relevant files, and it&#x27;s omniscient of all the actions that the user has taken independent of invoking the AI. (You can for example, start implementing a change manually and just ask Cascade to &quot;continue&quot;).<p>We&#x27;ve been using Cascade internally at Codeium on our actual production codebase, and we&#x27;re getting actual value from it. We hope everyone here does too! You can find a bunch of demos of Cascade on our website but I want to show one that I made myself using Cascade to solve an interesting cryptography challenge:<p><a href="https:&#x2F;&#x2F;youtu.be&#x2F;LbYepFmVB20" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;LbYepFmVB20</a><p>Cascade was able to explain the problem to me, install some libraries needed to interact with the challenge, give me some pointers towards a solution, and implement an attack that I described to it all by itself.
