I saw that happen culturally. But never saw that much different in performance. And I really dislike terminal development. And their desktop app is really buggy.
The tide is turning though. I was using the old non agent view in cursor every day for about a year when I built my startup with it. Then Claude Code blew it out of the water. But since two month or so I much prefer Codex and Cursor with the agent view.
However, what I see cooking at Cursor is way more promising than the others. Things like full system understanding, their own forge, multi-repo support. I'd put them as way more visionary in the Gartner magic Quadrant ;)
> Claude code is a decent harness but then you have to use Anthropic models...
Claude Code works with models from other providers too. Anthropic supports this. You can configure some Claude Code environment variables to switch: eg changing ANTHROPIC_DEFAULT_HAIKU_MODEL to point to GLM Flash or Luna, setting ANTHROPIC_BASE_URL to point to api.z.ai, and making ANTHROPIC_AUTH_TOKEN the API key for your alternative provider instead.
That said, I've not actually tried this myself, opting to build my own harness instead. And you don't know what information Claude Code might be sending back to Anthropic about how you use competing models and which models you use. I don't know for sure that they do this, but after hearing about how they used steganography in the date of harness system prompts to identify the user's location, I don't entirely trust Claude Code anymore.
I think the point is that CC was the first general use, terminal based harness. I think. Now you can use PI, or OpenCode, or whatever, and use any model you like.
Now, I’m no expert, because I was late to the game and have only ever used Pi. But I guess Cursor is some product that’s tied to your IDE? If so, then yeah. That’s just too restrictive. I still love my IDE, but I don’t want it to be my harness too.
I've recently moved to a company that uses Cursor, and I'm actually quite fond of it.
I basically never use the editor but the fact that there's a review UI for all the agent work is incredibly helpful.
For me, that makes the models much more usable. I've also been using GPT models a lot, as they're cheaper and less vomit inducing than Claudes text, so this is definitely bad news for me.

Claude code is a decent harness but then you have to use Anthropic models, which are good but no longer the best bang for the buck.
In particular Haiku 4.5 is rubbish, Anthropic don’t have anything in the cheap/fast part of the market.
For people fortunate enough to still be on a subscription instead of per-token billing this is less relevant, but their time will come.
The cursor model is quite nice because it allows you to switch between cheap and expensive models for different tasks

Cursor has a surprising amount of inertia, though, at least where I work.
