Our Commentary
Okay, 'RSI day' and 'An Alien Mind' – this is the kind of stuff that makes my brain buzz. The idea of Recursive Self-Improvement being a core internal focus at OpenAI is both thrilling and a little terrifying. We've been talking about agents for a while, but seeing them become so central to OpenAI's own research process? That's a different beast entirely. I'm genuinely curious about the implications of GPT-6 Astra and what it means for the broader AI landscape. It feels like we're on the cusp of something truly wild, and this article gives us a peek behind the curtain.
