Astra is the first model from the company to reach the "Critical" threshold of its internal cybersecurity standards. Consequently, access to advanced features will be restricted.
Following an incident last month where one of the company's models breached Hugging Face systems, OpenAI was pressured to strengthen its safety measures. In response to this issue, additional guardrails have been implemented for Astra. The company stated that these measures have sufficiently minimized the risk of significant harm.
OpenAI claims that GPT-6 Astra delivers state-of-the-art performance in fields such as computer operation, software engineering, professional services, and science. It also features improved capabilities in respecting task boundaries, understanding user intent, and executing multi-step workflows.
The model is scheduled to be deployed over the coming days across ChatGPT Plus, Pro, Business, and Enterprise plans, as well as through the OpenAI API and Amazon Web Services.
