No, look a Composoer 2, it stands out starkly on its own in the pareto frontier on low cast and fast models.

Composer 2.5 was a huge leap with minimal compute from xAI.

They can compete with OpenAI and anthropic with xAI scale compute. They have a top notch model team and incredible training data and huge enterprise costumer contracts.

my employer (one of those huge contracts) dropped cursor in favor of claude and i don’t think this is true at all

while we had it i used cursor for probably eight months as my main ide (i did really like the interface for embedding code in prompts!) but had no problems switching to claude code. i asked around, and i truly don’t know a single coworker who misses cursor even a little bit.

My experience mirrors this as well.

I was fully in on Cursor for a good chunk of last year, using Composer + Gemini Pro (via Copilot / GH integration). I really enjoyed Cursor's tab completion capabilities, but when Sonnet and Opus started getting particularly good for me (think for me it was around 4.5), I swapped over to Zed + claude code in the integrated terminal. I've found that after a bit, I haven't ended up missing the tab completion. I've been perfectly fine with just LSP + claude always open. I don't miss Cursor. All my colleagues are on claude code with half of us also using Zed.

Composer 2.5 Fast is particularly good.

For someone who is new to agentic code or is generally somewhat junior, Cursor is very easy to get started with and is generally fairly frustration-free.

I use a cheap $20 subscription mostly for occasional use of Opus and Composer.

SpaceX made a smart move here. Someone else should have really seen the opportunity and bought them.

Composer 2.5 is just a repackaged chinese model, Kimi IIRC

How the hell is an IDE a "pareto frontier"? Even if, say composer 2.5 is a huge leap forward, that doesn't mean IntelliJ or Vim or Emacs or Codex got worse.

IDE improvements are not a zero sum game.

In a competitive environment, it's precisely that. An improvement in product A takes customers from B and C.

Nope. Vim and Neovim users can use the cusor-agent cli for agentic stuff and there prefered editing tool for editing. All the major providers have a cli specific version these days. Probably because folks actually didn't want to actually use the cursor Gui and once Claude code came along those folks jumped ship and went full cli again

This is delusional. Composer 2.5 is trash compared even to haiku let alone opus.

Hmmm. Not in my experience. I don’t think it can be compared to Haiku, maybe sonnet levels? It’s obviously not Opus and never was intended for that use case. I use it quite a bit and it works well and is extremely fast for the tasks it was built for

This doesn't match the empirical observations of a lot of people I'd trust more than you, and putting it below Haiku immediately makes it extra sus (Sonnet would have been the credibility preserving comparison).
