Windsurf has a good free model. Good enough for autocomplete level work for sure (haven't tried it for more as I use Claude Code)

You mean SWE-1? I used it like a dozen times and I gave up because the responses were so bad. Not even sure whether it’s good enough for autocomplete because it’s the slowest model I’ve tested in a while.

Not my experience for slowness. For smartness I am typically using it for simple "not worth looking that up" stuff rather than even feature implementation. Got it to write some MySQL SQL today, for example.

Assuming you have to at least be logged into a windsurf account though?

Yeah. I didn't see not logged in as a requirement.
