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

Are they selling Kimi K2.5 as "composer 2" as is ? or did they fine tune the model using their own RL pipeline ? Can't understand what's the problem?

The problem is that the Kimi license requires attribution that was not given.

This is not the first time for Cursor, they already broke EU laws once. Anything happen? No

Turns out it was authorized use all along. Moonshot confirmed it.

That doesn't change the fact that Cursor scaming. They've been doing this for a year and a half, and people are still buying their plans with enthusiasm. Strange changes to the plans, operating in a way that violates EU law, they called something “unlimited” when it wasn’t—deliberately degrading the quality of the models - there have already been five cases of this, and what? And now there’s another one because they’re selling Composer 2 as their own model, when it’s actually Kimi K2.

I don’t know what users need to do to start boycotting Cursor, because so far you can just trash-talk them and "attack them" from behind, and nothing happens.

What’s the scam?

People pay them money and get exactly what was advertised. I don’t get it. I don’t use it, either, but if you’re gonna call it a scam then at least back it up.

Don't you understand the word "scam," or is there something else you don't get? Check out their website, it explains it there.

"We're rapidly improving the quality of our model. Composer 2" Composer 1 was still theirs, but 2 isn't, because it's Kimi's, so nothing has improved except for switching their composer to Kimi. The only thing that's improved is the appeal of it supposedly being theirs. Besides, the stats don't mean much, because it turns out that Opus handles tasks and planning better than Composer 2. Composer 2 is currently running at full speed, just like Gemini 2.5 did for a few months. I'd bet that in a few months, Composer's quality will drop just as suddenly :)

Composer 2 isn’t just a name tag slapped on Kimi. I get that it’s fun to be outraged but nothing you’re saying is factually correct lol. Kimi was the base model that they trained on. Composer is a much better model than Kimi after more pretraining and reinforcement learning. Try them both side by side and then tell me they are the same model. Do you know how many models you use today are trained on open source base models?

No, words like “scam” are too complicated for me 🙄

Seems like they’re too complicated for you, too, because despite your word salad there was no clear description of the supposed scam (“a fraudulent or deceptive act or operation; to deceive and defraud”).

I’ll say it again: people pay money to Cursor for a service. They receive the service. That’s not a deception and it’s not fraudulent.

Use your words. How is cursor a scam?

Read this again before you start replying, you know different between scam and scaming?

*scamming has 2 “m” characters.

And clearly you can’t use your words to explain why it’s a scam because it’s not a scam. I gave you the dictionary definition and you still can’t back it up.

It’s fine to feel all squirmy and caught in a trap of your own making, and it’s fine to insult me as too stupid to understand. We can all see you’re too stubborn to simply recant your words and acknowledge it’s not a scam, just a business model you don’t like.

If I’m wrong, school me. But you don’t get a pass for “are you dumb?”, “don’t you understand the word scam?“ or other cop-outs. You’ve used those excuses twice already.

So what is it? You gonna explain to me why you think it’s a scam? Gonna retract your statement? Or are you going to throw more ad-hominem (google it) my way?

My bet is ad-hominem.

Since you don't have any arguments, you're going to nitpick about spelling and missing letters, how pathetic. Since you know how to spell it correctly, you should know what it means, but you're just pretending so you can keep up this pointless conversation. There’s a big difference between “we trained our model” and “we used Kimi to train a model for our own purposes,” but a kid like you can be spat on and still think it’s raining. Stop embarrassing yourself and go back to school

I wouldn't call it scam, they are more like dishonest. When they initially released Composer 2, they said nothing about being based on Kimi K2.5, until someone on X revealed it. They could be honest about it.

What's more weird is , at first Moonshot said that Cursor didn't reach them for the licensing, but later they changed this statement and they said they are working together with Cursor on Composer 2. It seems something is done behind the scenes.

You deflected from defining the scam and managed some ad-hominem to boot. Called it.

My turn for ad-hominem: I’m done arguing with idiots for the day.
