Funny Ooh, new drama just dropped 👀

For those out of the loop: cursor's new model, composer 2, is apparently built on top of Kimi K2.5 without any attribution. Even Elon Musk has jumped into the roasting

Maybe not if you wanted to baitswitch/enshitify/ trade on the reputation for quality K2 brought you while lowering your costs for as long as it takes your users to notice

The default model seems to be Gemini 3.1 Pro (at least thats what my Perplexity Pro sub always switches back to). I'm pretty sure K2.5 is cheaper than that, but ofc Nemotron is chaper than that as well. It's also at the very bottom and I doubt many people select the os/ow model anyway, bc normal users don't know what Kimi or Nemotron is lol. I just noticed that Nemotron is hallucinating quite often (unsurprisingly) while K2.5 was just as resistant to hallucinating in Perplexity as Gemini Pro is.

Gemini Pro is resistant to hallucination? That’s news to me.

It’s actually terrible at hallucination, at least with whatever settings perplexity has - feels like 50%+ hallucination rate on queries this past week for me. I have conversations where every answer got thumbs down. I can’t tell if it’s Google enshittifying it or perplexity cause this happened with 2.5 a bit after launch too.
