Odaily News OpenAI announced the launch of the GPT-5.4-Cyber model. This model is fine-tuned based on GPT-5.4 for cybersecurity scenarios, reducing refusal restrictions on security-related requests under specific conditions to support professional operations such as binary reverse analysis.According to the introduction, the model is only available to vetted security vendors, enterprise security teams, and researchers through the "Trusted Access for Cybersecurity" (TAC) program. OpenAI stated that a layered mechanism will restrict the model's usage scope and impose additional constraints on access in low-visibility scenarios.
