There are many reasons to make fun of Cursor. However, one of the things get right is their autocomplete model.

Are there any open models that come close? Why doesnt OAI or Anthropic dedicate some resources to blowing Cursor's model out of the water? Cursor's completion model is a sticking point for a lot of users.

I agree, their autocomplete (tab) model is the best, but recently I realised I am using it less and less - the new models are so good that I mostly just do agentic coding, and I do very little changes in the codebase by myself. This is probably a general trend and if the usage of autocomplete models is dying out, it's understandable the companies are not investing resources into it.

Antigravity has an autocomplete model too. Based on Windsurf's, I guess.

The model is great. The UX is ~~horrible~~ annoying...

Most companies don't do auto competition these days, including some that just recently stopped offering completion.

Which I find very unfortunate. There are so many cases, especially in proprietary codebases with non standard infrastructure, where good autocomplete is much better than "agentic" edits that produce nothing but slop which takes longer to clean up.
