Today, I’m excited to announce the launch of Yupp, a fun and easy way to discover, compare, and use the latest AIs – all while helping to shape the future of the field.

The core idea is simple: instead of one AI response to your prompts, you get two (and more if you want them) from the best AIs in the world. Why would you want that? Maybe you’re curious. Maybe you like having choices. Perhaps you just want more than one opinion – because you know that any single AI can hallucinate, and you can never be fully sure if what you’re getting is right.

That’s exactly why we built Yupp.

For people who want to make their own decisions after consulting with many experts, not just one. For people who want to build their own “council of AIs”.

Yupp has over 500 models and counting: from ChatGPT and Claude to Gemini and DeepSeek, from Grok and Llama to text and image models you may not have even heard of. All of them, side-by-side, and all for free. You decide what’s best for you and are free to compare, contrast, and remix them as you wish.

And when you don’t want to read long AI responses, Yupp’s own QuickTake AI can give you a short, tweet-length response.

So how do we provide AIs for free? 

As you are browsing answers from different AI models, Yupp allows you to share which one you liked better and why, where they were right and where they fell short for you. Your feedback personalizes your future AI responses on Yupp to be better customized to your needs – and it’s what enables us to provide models for free. 

Our mechanism works through a system of points called Yupp credits. Everyone receives credits when they sign up for Yupp. These credits go towards using the AI models – even the most powerful and expensive ones like Claude Opus 4 or OpenAI o3 – but you’re rewarded credits for providing feedback. The higher quality your feedback, the more credits you get, so that you can continue to use the AI models for free.

All of your prompts in chats are always private, unless you explicitly make them public because you want to share them with the world. Even for public chats, your personal information is never shared, ever. We deeply value your privacy. You control when and what gets shared. To learn more, you can read our full privacy policy, and ask us any question at privacy@yupp.ai.

The world needs AI. AI needs you.

Your feedback helps tailor the AIs better for you, but it also helps the AI community build better models for everyone. Feedback from one user may or may not be reliable, but aggregating data from millions of users around the world creates powerful signals that can be used by AI model builders to improve their systems and agents. Using aggregate trends and privacy-preserving analytics, everyone can get a pulse of which models are performing better for which types of prompts. So if you are the sort of person who cares about making a meaningful contribution to the future of AI, you can, by simply using Yupp.

As a token of our appreciation and recognition of your contributions to the future of AI, we enable you to convert some of your credits to money in USD, Euro, and 20+ other currencies. We have partnered with payment providers like Stripe, Paypal, and Coinbase to meet our users where they are. We’ve also integrated stablecoins on Base Ethernet L2 and Solana blockchains to enable everyone in the world to get instant and free rewards in their pocket. 

The challenge of model evaluations in the field of AI

Beyond creating a better user experience, Yupp was founded to address a foundational challenge in the field of AI. Every AI builder wants to know how good their models or systems are, and for which use cases. Without this knowledge, it is not possible to meaningfully improve AIs. Thus, “model evals” are a foundational problem central to progress in the field. Because of the high-stakes AI race we are in, a great deal of attention is placed on model rankings in leaderboards. Unfortunately, recent research has shown that the existing leaderboard solutions have fundamental challenges, suffering from a lack of transparency, lack of fairness to participants in terms of model exposure, and lack of equitable access to evaluation data. These aren’t abstract concerns – they directly affect how AIs evolve and who benefits from them.

To tackle these challenges, we are launching the Beta version of our AI leaderboard today, ranking AIs by what we simply call the Yupp VIBE (Vibe Intelligence BEnchmark) Score. These scores are powered by rich and detailed preferences aggregated from users all around the world interacting naturally with Yupp. We’re taking a fundamentally different approach to forge a better way to evaluate AIs. The technical details behind our approach are interesting in their own right so we have detailed them in a separate blog post.

Our team and investors

I founded Yupp with my co-founder and AI lead Gilad Mishne in June 2024. Since then, we’ve assembled a cracked team of product builders and AI researchers. We’ve been in stealth, testing with friends and family for the last six months. We share our immense gratitude to each one of them for giving us valuable feedback that has brought us to the product launching today. The initial number of testers grew organically and rapidly as they enjoyed Yupp and spread the word to their own friends and family. Now we welcome you to join in, too!

We closed a seed round of $33M last year, led by the veteran investor and Internet luminary Chris Dixon at Andreessen Horowitz (a16z). Chris has been thinking about the protocols and economics underlying the Internet for a long time, including the bootstrapping of network effects (“Come for the tool, stay for the network”). In 2015, he wrote about how a large-scale crowdsourced approach to AI data is structurally better than alternative approaches. He has been one of the foremost evangelists of open-access and decentralized technologies like blockchains, stablecoins, and cryptographic protocols. These can help provide provable authenticity, fairness, transparency, and credible neutrality – all critical considerations for AI evals as explained in our complementary blog post. I’m thrilled to have his and a16z’s support in this journey.

In addition, we are proud to be backed by more than 45 individual angels and small investors who are among the finest builders, visionary thinkers, and tech executives – including Jeff Dean, Chief Scientist, Google; Biz Stone, co-founder Twitter; Evan Sharp, co-founder Pinterest; Aravind Srinivas, CEO Perplexity; Kunal Shah, CEO Cred; four professors at Stanford University (Prof Dan Boneh, Prof Chris Re, Prof Nick McKeown, Prof Balaji Prabhakar), Othman Laraki, Paul Grewal, Gokul Rajaram, and Coinbase Ventures.

Join us today by visiting yupp.ai 

If you look at the first iteration of any 21st century innovation – your phone or social media, for example –  they look almost nothing like they do today. Because it took time to figure out. And when it comes to AI... there’s still much to figure out. And more than any other technology innovation in history, AI depends on everyone participating and contributing. Yupp’s mission is to empower humanity to shape the future of AI.

Though a powerful technology, no AI is always right or has all the answers. Getting multiple opinions and perspectives can help you develop a more nuanced understanding, make better decisions, and ultimately get stuff done faster – all while making your mark on the AI era by sharing your feedback.

I hope you’ll visit yupp.ai today. We give you 5,000 credits to get started with, and if you use this special sign-up link by June 20 midnight PT, you will get an additional 2,500 credits. Remember, you can always get more credits as rewards so that you can continue to use the best AI models. We can’t wait to hear what you think.
