OpenAI claims that Astra is ‘the most intelligent and most aligned [available] model’ in the world.
GPT-6 Astra System Card - OpenAI Deployment Safety Hub
Today, we are releasing GPT-6 Astra, the most capable model we have ever broadly deployed. Astra is our first model to reach the Critical level of cybersecurity capability under our Preparedness Framework.
GPT-6 Astra: A new generation of intelligence
Introducing GPT-6 Astra, our most intelligent and aligned model yet, with state-of-the-art capabilities across computer use, coding, cybersecurity, and science.

GPT-5.6 System Card - OpenAI Deployment Safety Hub
GPT-5.6 is a new family of three models: Sol, our new flagship model; Terra, a capable lower-cost option; and Luna, our fastest and most cost-efficient model. The safeguards we have built for this launch—our most robust yet—are built to deliver these models safely and at scale, around the world.

Astra for Coding: Why Are We Doing This Again?
Some thoughts on Astra and newfangled long-horizon models.
OpenAI's GPT-6.1 Sol offers Astra-like performance at 1/5th price. A new Ultrafast tier clocks at 300 tokens per second.
Its obvious targets are applications where waiting carries its own cost: interactive coding, customer support, financial analysis, incident response and other human-in-the-loop systems.

GPT-5.6 Sol is the frontier model in the GPT-5.6 family. It roughly corresponds to the unsuffixed model tier used in earlier GPT-5 families. The gpt-5.6 alias routes requests to GPT-5.6 Sol.
Astra Is Hard to Monitor
OpenAI’s central message on Astra is that it is three things:
