Composer 2.5 prompt battle: Opus-level coding at a tenth of the cost

LLM prices have climbed all year, and the bill lands hardest on the people who code every day. Every refactor, every agent run, every long debugging session adds up. Managing that cost has quietly become part of the job.

Cursor's Composer 2.5 changes the math. You get Claude Opus 4.7-level coding at roughly a tenth of the cost. Independent testing from Artificial Analysis puts it third on the Coding Agent Index, behind only higher-effort Opus 4.7 and GPT-5.5; both cost around 10x more per task.

What is the Composer 2.5 prompt battle?

On Friday, July 3, we're running a prompt battle at CREATORS Space in Stuttgart. The rule is simple: one prompt, three minutes, and Composer 2.5 to build what we ask for. No second tries. No switching models.

You go head-to-head with other builders. Same problem, same model, same clock. The audience decides who shipped the better result. It's a clean test of one skill: how well you prompt one of the strongest coding models available.

How the day runs

Come anytime before 6 PM. Here's the schedule:

• 3:00–5:30 PM. Coworking. Grab a seat, open Cursor, and build alongside other people.
• 5:30–7:00 PM. Prompt battle. Same problem, same model, three minutes per round.
• 7:00–9:00 PM. Dinner and networking.

Free Cursor credits for everyone who shows up. Food and drinks are on us. You bring your laptop and your sharpest prompts.

Where: Epplestraße 225, Haus 3, 70567 Stuttgart, Etage 1.

Reserve your spot on Luma.
