XAI has announced the integration of Grok 4.3 into Nous Research’s open-source Hermes Agent, effective May 15, 2026. This integration enables users to leverage Grok’s text conversation and advanced reasoning features within the Hermes Agent environment. Hermes Agent is designed to run persistently on any computer, sandbox, or VPS, creating long-term memory across sessions and learning as it is used. The agent supports connections to various messaging platforms including WhatsApp, Discord, Telegram, and Signal. With Grok integrated, users can also utilize Grok Text-to-Speech for spoken responses and Grok Imagine for generating images and videos. The integration is available across all subscription tiers of Grok. To set up the connection, users must first install Hermes Agent using the provided script and then select the XAI Grok OAuth option for their subscription. The process involves signing in through a browser and initiating chat sessions. For further details, users are directed to the Hermes Agent xAI Grok OAuth documentation. More open-source agents and integrations are expected to be released in the near future. *Source: [xai](https://x.ai/news/grok-hermes)*
