"Yupp makes testing AI models fun and rewarding"

Yupp lets you run prompts through over 500 AI models (like ChatGPT, Claude, Gemini, Grok) side by side, and pick which answer is best. You earn “Yupp credits” for voting and explaining why, which can be cashed out via PayPal, Venmo, or stablecoins on Base and Solana up to about $50 a month. What I find cool is how it gamifies a process that’s usually boring: voting, scratching for random reward points, and climbing a public “VIBE” leaderboard that ranks models based on real user opinions. Backed by a $33M seed round led by a16z crypto (with Biz Stone, Jeff Dean, Coinbase Ventures, and more), Yupp combines serious Web3 transparency (blockchain logged preference data) with consumer-friendly design.
