this feels super bullish on cursor/spacexai's ability to train a frontier level model. could be truly SOTA on coding given that their RL data is this powerful

Re: Cursor Introduces Composer 2.5
#32Surprised this got pushed off the front page so quickly! It’s exciting to see what the Cursor team has been able to do with significantly fewer resources than the frontier labs.
I do wish they weren’t joining xAI. Something tells me there will be a contingent of researchers that departs Cursor if that merger is consummated.

#33If these benches from their site hold up (they likely wont)
Wouldn't this compress ai revenue like 15x quickly
If they really have a 4.7 opus high equivalent at 1/16 the cost wouldn't this significantly effect all the current capex and planing
Maybe they are getting elon to cover cost
Re: Cursor Introduces Composer 2.5
#34The model is (like Composer 2) based on Kimi K2.5 and they claim SOTA performance for 1/10th of the cost. The tweet also mentions that they've started a new model from scratch on Colossus 2 (xAI/SpaceX Cluster). Really impressive how they've made this jump from being called the vscode fork with no moat just a couple of months ago.
> Really impressive how they've made this jump from being called the vscode fork with no moat just a couple of months ago. Impressive, yes. But they still don't have a moat...
Isn't a large user base and the data collected from those users a moat of sorts?

#35I don't know why their model isn't on Openrouter yet. They must not have enough capacity to offer it.

Honestly the data itself is probably worth heaps even in the company itself collapses. Early attention engineering when humans were still in the loop!!!

A moat is when you have something other's can't easily get.
Every MAG 7 / FAANG company already has more users and more data...
That's not a moat.
That's traction.

this thing is so awesome on fast mode, so far i am impressed, some of its observations feel similar to opus.
i use gpt 5.5 and opus 4.7 a lot every day, if i can get good results at this speed, hopefully the usage level holds up on my team plan haha

I am not sure we should dismiss what they have today. Nobody has yet to come close with a full package ide that works well for coding. Is that not a moat? It is easy for my to in my head discount it, thinking that I could build something myself but between autocomplete and their workflow for agent use, it feels like they have some tangible moat emerging.
Re: Cursor Introduces Composer 2.5
#40They set themselves up for flack when they use whatever these evals are… they did the same for composer 2 which was evaled in close competition with frontier models, spoiler alert, it wasn’t even close in practice. So now 2.5 is supposed to compete with opus 4.7? Sure…
As I have said before in prior composer threads. The proof is in the usage. I am inclined to somewhat believe the results as I use composer and also take the results for the given context. It’s not a general purpose sota model. It’s a model that runs inexpensively in their coding workflow that is creating results similar to opus or gpt.
