Arena.ai Plus

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.
