Developers can access Astra in the API as gpt-6-astra or through Amazon Bedrock, OpenAI said, priced at $10 per million input tokens and $50 per million output tokens. Pro, Business, and Enterprise users also get a variant called Astra Pro, and the company said Astra supports Zero Data Retention for eligible API customers.
Company claims perfect score on exploit benchmark
OpenAI said it tested Astra without production safeguards on ExploitBench, and that the model scored 100%, up from 78.5% for predecessor GPT-5.6 Sol. On ExploitGym, a broader exploit-development benchmark, the company said Astra reached a 42.4% success rate against 30.3% for Sol, while using fewer output tokens.
“Its ability to identify and develop zero-day exploits can help defenders find and patch weaknesses, but it also creates a need for stronger safeguards,” OpenAI said in the blog post.
