OpenAI Releases GPT-5.2 System Card Update
OpenAI has published a system card update for GPT-5.2, the latest model family in the GPT-5 series. The safety mitigation approach is described as largely consistent with the prior GPT-5 and GPT-5.1 system cards. Training data sources follow the same pattern as other OpenAI models: publicly available internet data, third-party partnerships, and user/researcher-generated content.
