Description
Arthur is an AI monitoring and guardrails company, with Adam Wenchel as chief executive, that helps teams deploy language models safely in production. Arthur Shield acts as a firewall between an application and a model, validating prompts and responses to block prompt injection, sensitive-data leakage, toxic content, and hallucinations before they reach a user. The Arthur Engine is available as open source for running guardrails and evaluations, while the enterprise platform adds model monitoring, custom metrics, and on-premise deployment.
