GPT-6 Astra: What’s Actually New in OpenAI’s New Frontier Model

OpenAI has released GPT-6 Astra, its newest frontier model, less than a week after Anthropic’s Claude Fable 5.1. OpenAI calls Astra the world’s most intelligent and aligned model yet. What actually makes Astra different? The simplest way to put it is this: Astra is built to do more, not just answer more. It can use a computer to complete tasks instead of telling you how to do them. It can create finished documents instead of giving you a rough first draft. During long coding sessions, Astra can also remember what happened earlier instead of starting from scratch. And it’s better at knowing when to take action and when to stop and ask. The bigger shift isn’t just smarter answers. AI is getting closer to actually getting the work done. Some important caveats remain, though. Astra doesn’t beat every competing model, and some of its biggest benchmark numbers come with asterisks. Let’s look at what’s new, what Astra does well, and where the caveats are.
