I built RIVAL to see how different AI models respond to the exact same one-shot prompt, side-by-side in a visual way. It lets you compare one-shot responses from models like GPT4.5, Claude Sonnet 3.7, Grok 3, and others across different challenge types (coding, web design, SVG generation, text analysis).
