Cursor drops custom LLM with 4X speed gains

“Cursor just proved that sometimes the best way to go faster is to build your own engine—4X faster, to be exact.”

Hello Builders! 👋

The AI coding wars are heating up as Cursor launches Composer, their first in-house LLM promising massive speed gains, while OpenAI expands Sora access globally and developers everywhere are leveling up their prompt optimization game. It's a big day for builders looking to ship faster and smarter.

Cursor just dropped their own LLM called Composer, and they're claiming a 4X speed boost. Bold move for a company that's basically been the poster child for wrapping other people's AI models in a slick interface. Now they're playing in the big leagues with OpenAI and Anthropic.

Here's the thing though—4X faster at what exactly? Autocomplete? Whole file generation? Making me feel inadequate about my coding skills? The devil's in the details, and we need to see some real benchmarks before we start throwing confetti.

The builders who win won't be the ones with the most features. They'll be the ones who made people feel something in the first 30 seconds. Speed and emotion are eating strategy for breakfast.

So what are you building right now? Not the polished pitch version—what's the actual thing you're wrestling with this week? The feature that won't behave? The positioning that feels off? Hit reply and tell me. I read every response, and honestly, your builds inspire half my best ideas.

Keep shipping,

P.S. If you haven't shipped anything in the last 7 days, this is your sign. Deploy something today—even if it's broken, ugly, or just a landing page that says "I'm building this, want in?" Momentum beats perfection every single time.
