We have an explanation here: https://blog.sweep.dev/posts/next-edit-jetbrains#next-edit-a...

But basically suggesting changes away from your cursor position

It's a bit undertrained on C#, we'll continue improving on this!

Also wish Fleet took off, not a fan of installing a new IDE for every separate repo that's in a different language

I've done some testing before and many of the new Jetbrains internal plugins cause memory leaks which really lags down my IDE...

Definitely agree here, have had so many cases where I would like ask Claude for XYZ, then ask for XYZ again but with a small change. Instead of abstracting out the common code it would just duplicate the code with the small change.

We currently integrate with Jetbrains' PSI

Honestly I think we can improve our training throughput drastically via a few more optimizations but we've been spending most of our time on model quality improvements instead.

You can see that Qwen3 does worse than Qwen2.5 on our benchmark. Reason is it's never been pretrained for FIM / autocomplete.

Not at the moment but we do host it for our Jetbrains plugin

Yes, I've used it to write blog posts / large user-facing copy.
