OpenAI releases GPT-5.5 system card detailing safety testing and capabilities of its latest AI model

OpenAI published a technical document (System Card) for GPT-5.5, a new version of its large language model (AI that understands and generates text). The document outlines how the company tested the model for safety risks, including potential for misuse, and what real-world tasks it can handle.

The System Card reveals OpenAI's testing methodology—how engineers checked whether GPT-5.5 could be used to generate harmful content, manipulate people, or bypass security systems—and describes which safeguards the company built in before release. This level of transparency is rare in the AI industry, where most companies keep such details private.

For business professionals and AI teams evaluating whether to use GPT-5.5, the System Card provides concrete evidence of safety measures rather than marketing claims alone. For regulators and policymakers watching AI deployment, it sets a precedent for accountability that competitors may now face pressure to match.
