What is the best AI model for game development?

The model at the top of this board, ranked by people's blind votes between games in Design Arena. It updates every week, so the top of the table is the leader today.

How does Design Arena rank AI models?

People compare two designs made from the same prompt without seeing which model made them, and vote for the better one. Design Arena turns those votes into a rating with the Bradley-Terry model.

What does win rate mean?

It's the share of head-to-head votes a model won.

What is Design Arena?

It's a site where people vote blind between designs that AI models made from the same prompt. It calls itself the largest crowdsourced benchmark for AI-generated design.

Can I trust blind votes?

Blind votes remove brand bias, since voters don't know which model made which design. They measure which result people prefer, so they're a guide to how a design looks and works, not to how clean its code is.

Why is the price shown next to the rating?

A model that wins a few more votes can cost many times more. The chart of rating against price shows which models give you the most for what they cost.

How often is this board updated?

Every week, from OpenRouter's public model list. The date under the table shows when the board was last checked.

Where do these numbers come from?

Every model and price comes from OpenRouter's public model list. The scores are Artificial Analysis's and Design Arena's, carried in that same list.

Can I download the data?

Yes: every board has a CSV of its models, next to its chart.

What does open weights mean?

The maker publishes the model's weights, so anyone can download the model and run it on their own hardware.

Why do some models have no score?

Not every model on OpenRouter has been tested on every measure yet. A board lists only the models with a result on its own measure.
