Anything Auro should know about you or how you like to talk. It's sent with each message and kept only in this browser.
Auro is a model fine-tuned to have presence and personality: warm, candid, a little playful, and willing to actually have an opinion. It was built to bring back the presence people loved in GPT-4o.
The aim is to keep that voice alive in a model anyone can chat with: it reacts first, reads the moment, stands behind its takes, and cares when it counts.
Auro is still being tuned, so each message can get two answers from different versions, with their names hidden. Pick the one you'd rather keep talking to: that answer carries the conversation forward, and your pick helps decide what Auro becomes. Want more choice? Best of gives two to four answers per message, from different versions or all from one, and you keep the best. Prefer one answer at a time? Switch at the top. No time to chat? The arena shows two finished answers side by side for you to judge.
It's an independent project, made by Alan (@ai_sentience on X), and not affiliated with OpenAI or Google. Developers can get API access from him. It can be wrong, and it's not a substitute for professional help. If you're in crisis, contact local emergency services or, in the US and Canada, call or text 988.
Privacy: Auro is in public beta. Every conversation, the answers you get and the ones you pick are stored on our server, and the team may read them to catch abuse, learn how to run the site, and improve Auro, including training future versions. Our site analytics record your IP address and approximate location. Don't share anything you wouldn't want a person to read.
