AI models a new attack vector for hackers. They can use AI models to generate malicious content, spam, or phishing attacks. OpenShield is a firewall for AI models. It provides rate limiting, content filtering, and keyword filtering for AI models. It also provides a tokenizer calculation for OpenAI models.
