Anthropic is piloting Claude, an AI agent, in Chrome to test its browser-based capabilities while addressing safety and security concerns. The pilot aims to refine Claude's prompt injection classifiers and underlying models to prevent malicious actors from tricking the AI into taking harmful actions. The company is starting with controlled testing, allowing trusted users to instruct Claude to take actions on their behalf within the browser. Claude's capabilities will be expanded to more users as the company develops stronger safety measures.
