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.
