OpenAI released the system card for GPT-5.5, documenting the model's technical specifications and risk assessment process. The card follows the company's standard format for disclosing model behavior before public release.
System cards serve as technical disclosures that detail pre-deployment testing, identified risks, and mitigation strategies. OpenAI has published these documents for each major model release since GPT-4.
The GPT-5.5 card provides benchmarks, safety evaluation results, and the decision framework used to authorize deployment. OpenAI published the document alongside the model's availability.
