OpenAI claims that Astra is ‘the most intelligent and most aligned [available] model’ in the world. Not the most intelligent and aligned OpenAI model, but the most period. That is bold talk. It risks overstepping, and by doing so souring the release of what is clearly an excellent model. As...

OpenAI’s central message on Astra is that it is three things: 1. Highly capable and can do all the things for you. 2. Hard to monitor. 3. The most aligned model. The first claim largely checks out. Astra and Fable are both clearly excellent models. This post is about their...
