# Vitalik Buterin Launches AI Agent Privacy Mode Using zkAPI By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/34443 Published: 2026-10-18T18:00:36.000Z Updated: 2026-10-18T18:00:36.000Z Section: Technology > The system combines zkAPI, Tor, traffic obfuscation and local prompt rewriting, and accepts Ether and USD Coin deposits. Ethereum co-founder Vitalik Buterin launched a [privacy mode for his AI agent]() on Oct. 16. The privacy mode combines local software with zkAPI payments to obscure users’ identities, request origins and payment trails. An OpenAI-compatible daemon combines zkAPI, Tor, traffic obfuscation and local prompt rewriting. The system also includes a wrapper for the pi agent framework. It accepts deposits in Ether (ETH) and USD Coin (USDC). Buterin assessed the mode as usable, while noting that starting a new conversation is slow. Agents are also restricted to a software sandbox. ## Links in this article - [privacy mode for his AI agent](https://www.tokenpost.com/news/technology/33434)
