Calling it an IDE is under-representing cursor
They have in-house models, and the data to train even more powerful ones. The cursor team is a proper AI lab.

On the contrary, it's over selling it: it's a not even a stand-alone IDE (like Zed, for instance) it's a mere fork of VSCode.
In the same sense that chrome is just a safari fork I suppose
Safari isn't even open source, and Chrome has never been a fork of Safari.
But yes Blink definitely started as a Webkit fork, and everyone would have found that laughable if someone bought that a proprietary fork of Webkit for $60B.
Isn't their in-house model just Kimi?
See here https://cursor.com/blog/composer-2-5
85% of the compute for the final model is from them, and not the base Kimi model.
That just means it cost a lot.
Does it perform meaningfully better than the Kimi model given all that extra compute? And proportionally to the amount spent?

They use Kimi and post-train it on the same stuff that anyone with a Github dump can feed it. They aren't doing anything that you can't do yourself.
Dumping github into a model is not post training, thats pre training. And every base model already has all of github.
Composer post training is clearly very good, only second to Anthropic and OpenAI.
It does irk me a bit that they try to hide the fact that it's based on a chinese pretrained model though.
why comment on something you clearly don't know anything about? it's on-policy RL trained not just on coding text
listen and learn :)
Meh. On an outcomes analysis, I've found Cursor's delivery to be exceptionally weak.
Good luck to the alt-economy of SpaceTesla though, may all our 401ks survive.
Their “in house models” are reportedly basically just Kimi.
Replied on the other comment about this, but putting it here:

Of course they could be lying, but it seems feasible that they are adding a lot on top of this
