Composer 2
The second generation of Cursor's coding model, built for a world where agents write most of the code rather than assisting edit by edit. Cursor pitches it as competitive with frontier models on coding while being markedly faster and cheaper.
Where it comes up
How Cursor uses Cursor
“that process and allow the agent to do a lot more testing and do it at a very high level of accuracy. Amazing. We'll shift into the discussion about models and how we are thinking about different models within Cursor, specifically focusing…”
Training Composer 2
“kind of this again. Um, so, right. Hi, I'm Sasha. I'm a researcher here at Cursor. So, I'm going to talk today about Composer 2. Uh, this is our in-house coding model. Um, so, uh, Composer 2 is this model that we built for agentic coding. U…”
Cursor 101
“something like OpenAI, or you can select uh Codex, you can select Grok, or excuse me, open-source models, or even Composer 2, which is Cursor's own model that's trained um on writing code specifically. So this stance of model neutrality is…”
Cursor x Datadog
“Um help me visualize this with canvas. Just new {slash} canvas here. This is a built-in skill. You all should be able to see it. Um and um make it so that it is clear enough that I can present it to engineering leadership. I'm going to use…”
Cursor for Knowledge Work
“Um, and the agent will go ahead and start analyzing the data, um analyzing and synthesizing, and returning the results I'm looking for. While it's thinking, um I did want to touch on that right now. I'm using Composer 2 fast model. Um, this…”
Cloud Agents
“I like to actually go to this uh UI for new changes. As you can see, I can choose what repository I'm working in, so I can change repositories really easy. But then I can also choose what model I'm using. So, I think this is a good thing to…”
Cursor 101
“Claude, GPT, Gemini, and then we have our own in-house model as well, uh called uh Composer 2. And um and that's really nice because I mean, I'm sure you've seen on the news, there's just so many models that come out all the time. And it's…”
Cursor for Designers
“Cool. So starting with the Agents window. Quick tour. As I mentioned, the agent is front and center. So here is where you're going to be doing most of your work with Cursor. This is where you're going to be doing your prompting, where you'r…”
Cursor Automations
“on a new feature, I always, you know, say, "Is this code regressing anything outside the feature flag?" And I'll kick that off with Opus or GPT-4 or Composer 2. Or I'll say, "You know, make sure this isn't regressing like this specific feat…”
Cursor CLI
“in? What MCPs do I have access to? And one of the things that, um, you know, we'll start with here at the very very beginning is just like let's do something pretty basic. Let's switch from the model that I'm currently in, which I think is…”
Model Selection & Token Efficiency
“And then scope out the context, right? So, if you have specific files, specific skills, or sub agents that are relevant to the task at hand, make sure to loop those in as well. Finally, execute that. Use Composer 2, fantastic execution mode…”
