About

Arena.ai Plus is a Chrome Extension that enriches the Arena.ai leaderboards with exclusive columns and quality-of-life features — helping you save on API expenses by picking the smartest model at the right price.

Key Features:

1. "Bang for Buck" Index
The core value metric — designed to surface the smartest models for the lowest price.

Measures relative intelligence against cost using a logarithmic pricing curve.
Applies a quality bonus to top-ranked models so elite-tier performance is weighted fairly.
Helps you identify which models deliver the most intelligence per dollar.
2. Deep Model Insights

Model Age — See how many days since each model was released, so you can spot the newest contenders at a glance.
Modalities — Visual icons indicating support for Text, Image, Audio, or Video (both Input and Output).

3. Generation Alerts
Get browser notifications when a generation completes — works in Battle, Side-by-side, and Direct chat modes. Perfect for long code generations where you've switched to another tab!

4. Seamless UI Integration
Plus columns appear directly inside Arena's built-in "Edit Columns" panel, so you can toggle them on or off alongside native columns. All injected columns are fully sortable.
