OpenAI has begun rolling out Lockdown Mode, an optional security setting designed to offer users advanced protection from prompt injection attacks.
For the unfamiliar, prompt injection is a form of social engineering that is specific to conversational chatbots.
As AI systems have become better at pulling information from the internet, people have begun hiding malicious instructions on webpages and other places to try and trick those systems.
OpenAI is billing Lockdown Mode as a sort of last line of defense against prompt injections, building on the robust protections that it says it already offers through ChatGPT, its models and backend systems.
"Lockdown Mode is not intended for everyone," OpenAI explains.
