OpenAI’s Greg Brockman: Z.ai’s GLM-5.3 likely to “significantly accelerate the threat landscape”

OpenAI president Greg Brockman warned that Chinese AI company Z.ai's upcoming GLM-5.3 model poses a growing cybersecurity risk, citing its strong performance on coding and vulnerability-finding tasks. Z.ai plans to release the model's weights publicly in late August, while OpenAI restricts access to its own cybersecurity models through identity verification and hardware security keys. Security experts debate whether GLM-5.3 truly represents a significant threat escalation, with some arguing that open-weight models' ability to remove safeguards matters more than raw benchmark performance.
