Cursor 201
“Okay. So, one just quick announcement. Uh first first up before we get into it, um you might have seen this yesterday. We we just launched uh our newest version of Composer, our own model here at Cursor. So, this just came out, 2.5. You can…”
Training Composer 2
“It scores similar to Opus 4.6 upon release and, uh, slightly behind GPT-5.4. Composer 2 combines really strong coding speed with a very competitive price. So, it's extremely efficient for using for all sorts of coding tasks. Uh, a lot of pe…”
Cursor for Designers
“know, click on let's say I'll click on this guy right here. Go ahead and just say make this font maybe three times as big and bright red. And what it'll do is it will give this div as context to cursor as along with a screenshot and it will…”
Cursor 101
“you can build and choose a model. It automatically selected composer two, which is great. That's what we want. That's cursor's in-house model optimized for coding, trained just on code, not for high reasoning, but specifically to uh to um j…”
PRD to PR
“of you have already seen this. If you open it for the first time, you'll probably be opted into auto automatically. But if you untoggle that, you can see kind of all of the different models. And we'll we'll briefly talk about some of the mo…”
Cursor for Data Science
“just because 5.3 is really smart, really fast, and a lot less expensive. Um, but I also would highly recommend folks trying out, you know, Cloud 46 Sonnet, which came out yesterday. Gemini 31 Pro just came out, I think like maybe an hour ag…”
Cursor for Java Developers
“all the chats I had with Intelligj. And um down here you can have different modes. You have ask mode, plan mode, and agent mode. Um later on I'll dig deeper into plan mode, but right now let's focus on ask mode here. And on the right hand s…”
Model Selection & Token Efficiency
“repository. It involved a sequence of steps and cognition, so it was a good idea to use a higher thinking model. But when it comes to actually executing these clear uh well-thought-out steps, this is where you're going to save tokens by uh…”
Cursor for Support Teams
“Um, we're using cursor's composer one model, which is our highly intelligent state-of-the-art model that was released last week. Um, and as you can see, there's context that's um, provided basically from the front end all the way through to…”
Cursor for Financial Services
“providers openai google anthropic xai and beyond this also building our own internal knowhow as to specialize machine learning models that are purpose-built for the coding use case like composer one. uh beyond this you know in terms of cove…”
Cursor for Quality Assurance
“of of endpoints here and different types of functionality that I have in my codebase. And so now when I write unit test, it'll be consistent with the um the structure of the rules that I've set out. So uh we'll go ahead and test this right…”
Cursor Rules, Commands, Hooks, and Skills
“ideally get even better output. So, uh, I'm going to go ahead and submit this. And then, and again, what I did here in sub agents is I clicked new, and that brought this, uh, pre-written prompt. And then you can see here the model is now ge…”
Refactoring Legacy Codebases
“And so, one of the um when it comes to models, right, within cursor, we're going to provide you with access to a few different ones. Um Composer 2.5, we just released last uh just a few days ago and this is benchmarking very well compared t…”
Cursor 2.0 Launch
“models like sonnet or gp5 uh codecs work really well for this. Then when you want to actually go and build you can choose to build on your machine or you can build it in the cloud. And we're going to decide here to build locally on our mach…”
Cursor 201
“So if I come over here to a new agent, I'm in my Grafana repo and I want to create a cloud agent for this. So I'm just going to go to this drop down and select cloud. Um, and I'm going to ask it to use my identify tech debt skill. Um, I can…”

Cursor for Product Managers
“you wanted to use Opus if you're a big fan of that, uh, we also have our own built-in model, Composer 1, which was it's a Frontier model that's built specifically for coding. Um, and we highly recommend. It's very intelligent and very, very…”
Cursor Automations
“Um in this case, I chose composer two for it. Um and it has a screen recording, too. Let me put this on 2x speed here. It goes to the localhost that it spun up, plays around with the toggle button, indeed showed me that, "Hey, it's dark mod…”

Cursor for Knowledge Work
“So then maybe the next follow-up question is I see this one top user, but now I want to know the top model used. And you can see it actually goes ahead and does a sum of the usage. Looks like Claude Sonnet 4.5 is the top top model used. Um,…”
Cursor for Mobile Developers
“But, we're going to do that through the agent window here. So, I'm going to go in here and I'm going to say and I'll use composer to fast so you you can kind of see this happen quicker. Can you update the lenses tray to be a button. Oops. A…”

“Awesome. Yeah, and it seems like there's a lot of questions in that vein as well. So, hopefully we we we ticked a couple of those off. Um, yeah. I'm just going to go through cuz I know that we are at time. Um, again, we have a short session…”
