More information

The following documents are applicable: OpenAI has incorporated additional safety measures including new techniques to help the models refuse unsafe requests. These advancements make the o1 series some of the most robust models available. OpenAI measures safety by testing how well models continue to follow its safety rules if a user tries to bypass them (known as "jailbreaking"). In OpenAI's internal tests, GPT-4o scored 22 (on a scale of 0-100) while o1-preview model scored 84. You can read more about this in the OpenAI's system card and research post .

Responsible AI considerations

GPT-5.4 poses an elevated risk of producing explicit content, compared to previous versions of the model. We recommend that customers evaluate content filter settings on production systems before launching and conduct appropriate post-launch monitoring. All customers must comply with the Microsoft Enterprise AI Services Code of Conduct. Configuration options for content filtering vary when you deploy a model for production in Azure AI; learn more .
