## AI overview

GPT-5.5 is presented as a model for complex real-world work, including coding, online research, information analysis, document and spreadsheet creation, and tool use. The system card describes predeployment safety evaluations, targeted red-teaming, feedback from nearly 200 early-access partners, and safeguards intended to reduce misuse while preserving beneficial uses. It also notes separate consideration of GPT-5.5 Pro and additional safeguards for deployment in the API.

## Source excerpt

GPT-5.5 is a new model designed for complex, real-world work, including writing code, researching online, analyzing information, creating documents and spreadsheets, and moving across tools to get things done. Relative to earlier models, GPT-5.5 understands the task earlier, asks for less guidance, uses tools more effectively, checks it work and keeps going until it's done.
