  "account": "On 3 September 2026, OpenAI released its latest model, GPT-6 Astra, which the company rated as Critical for cybersecurity risk. The announcement emphasizes that the model can find previously unknown security flaws and develop new ways to exploit them across many well-protected systems without human guidance. The release includes new safeguards such as misalignment monitoring, new blocking alignment evaluations, and restricted deployment access. These measures were implemented due to the model's ability to chain unknown flaws without human intervention. OpenAI co-founder and president, Greg Brockman, expressed his belief that GPT-6 Astra marks the beginning of the AGI era, although this is not a formal measurement. The system card provides information about the model's performance on various tasks, including its prompt-injection attack success rate of 8.5%, which is an improvement from its predecessor, Sol, with a rate of 27.0%. Despite this reduction in attack success, the number still represents a real threat, particularly when considering the various paths in which attacker-controlled text can reach the context of an agent.",
