GPT-5.5 System Card

GPT-5.5 is a new AI model from OpenAI designed to handle complex work tasks like coding, research, and document creation with less user guidance than previous models. OpenAI conducted extensive safety testing including red-teaming (simulated attacks by security experts to find vulnerabilities) and feedback from nearly 200 early partners before release, and deployed it with what they describe as their strongest safeguards to date.
