Frequently Asked Questions & Privacy Guide

The AI Multi-Model Arena allows developers, writers, and researchers to benchmark generative models side-by-side with 100% private in-browser execution.

Is my API key or prompt private?

Yes, 100%. All keys are stored solely in your local browser’s localStorage. API calls travel directly from your browser to Google Gemini, OpenAI, or your local runner. No data touches our servers.

Can I run Google offline models?

Yes. Google Gemini Nano can be executed offline via Chrome Built-in AI without an API key. Google Gemma 2 (2B, 9B, 27B) can be run locally via Ollama or LM Studio completely air-gapped.

How is device freezing prevented?

The tool auto-profiles your device RAM. If you select a heavy model that exceeds your physical RAM, an advisory warning appears. A 45-second watchdog timer and 1-click Stop button prevent UI thread locks.

Are live speed & token metrics accurate?

Yes. The arena tracks total elapsed latency in milliseconds and subword token counts to give you real-time tokens-per-second throughput comparisons between models.
