What Did OpenAI's Astra Change for Computer Use?

Ari Weinstein says Astra moved computer use forward at the edges even though computer-use models were already strong before Astra. It is a little faster on average because it uses fewer thinking tokens to do the same task. It is better at creative work, and it is more reliable around the edges.

In the launch video, someone talks to the model while it draws in Microsoft Paint, and Astra is way better at that sort of work. Weinstein thinks the improvement probably transfers to other creative tasks. He trusts it a little more. A small difference that is hard to perceive still matters between something being 99 percent reliable and 97 percent reliable, and Astra sits a little higher in a way that feels concrete.

OpenAI adds that Astra is also its most aligned model. The system card shows it is much better at resisting prompt injection and much better at avoiding unintended actions. For enterprise work on sensitive things, whether procurement, talking to vendors, or talking to customers, people are going to feel a lot safer using it.
