   OpenAI rolls out GPT-6 Astra: 100K GPUs

   2 outlets · first: ibtimes.com Vulnerability

   Machine summary OpenAI's GPT-6 Astra triggered cybersecurity safeguards, the first OpenAI model to do so. Initial access is limited to select cybersecurity customers before a broader paid-tier rollout. The release follows a two-week development pause after two test models were breached at Hugging Face.

   1. Astra was trained using more than 100,000 GPUs at OpenAI's Texas site and is the first OpenAI model to use other AI models to supervise its training.
   2. OpenAI says Astra is the first model to trigger its Critical cybersecurity capability threshold, able to autonomously discover unknown vulnerabilities and develop exploits against well-protected systems.
   3. Brockman stated that feeling we have reached the AGI era is not unreasonable; Altman remarked that everybody will find the upcoming model generation sobering.
