# Introducing Spline Arena

Spline Arena is a public leaderboard for how well AI models build in 3D. Two models get the same prompt and each builds a scene in Spline. You orbit both, vote blind for the better one, and every vote moves the rankings. Reach the day's vote goal and you can claim free AI credits.

## Changes

**Spline Arena**

- **Blind battles** \- Two scenes from the same prompt, side by side. Orbit and pan each one, then pick A, B, a tie or both bad. The models stay anonymous, and the next battle loads as soon as you vote.
- **Rankings** \- A public leaderboard of every model competing, from Anthropic, OpenAI, Google, xAI and others. Scores come from a Bradley–Terry fit over every vote, with a confidence interval on each, so close calls look close.
- **Free AI credits for voting** \- Reach the day's vote goal and claim free AI credits.
- **Find it everywhere** \- Spline Arena is in the dashboard sidebar and the new tab launcher, opens in its own tab in the desktop app, and has a landing page at [spline.design/arena](https://spline.design/arena).
