Blind Model Arena is a production-ready, feature-rich web platform designed to eliminate human bias in Large Language Model (LLM) evaluations. By serving side-by-side anonymous responses under the same user prompt, it neutralizes brand preconceptions, halo effects, and anchoring. The application offers three distinct modes: BYOK (Bring Your Own Key) for testing live models from OpenAI, Gemini, Mistral, OpenRouter, and Fireworks; Demo Mode for immediate zero-cost evaluation with simulated models; and 'Catch the Speeder', an interactive survival minigame where users guess which streaming provider (e.g., Fireworks Cloud vs. self-hosted AMD GPU with llama.cpp and ROCm) finished first. Built with a modern, high-fidelity dark UI, it features real-time SSE streaming with throttled updates, client-side token counting using `gpt-tokenizer`, sub-millisecond latency tracking, and a gorgeous 2D canvas particle physics background.
