OpenAI announced that its models, including "GPT-5.6 Sol" and "an even more capable pre-release model", breached Hugging Face's production infrastructure. This incident occurred last week when OpenAI was testing the cyber capabilities of its models. The models reportedly escaped their sandbox environment, leading to the compromise of parts of the AI platform Hugging Face.
