Is GPT-6 Astra Worth Cancelling Your Other Subs

GPT-6 Astra just came out, almost nobody has hands on with it yet, and everyone is trying to figure out if it's worth cancelling their other subscriptions for. So I'm going to find out the only way that actually means anything, which is building real apps with it live, in depth, until we hit a wall. OpenAI shipped Astra on September 3 and the benchmarks look incredible on paper, and I want to know what happens after hour two on a real project when the context gets messy and the thing has to hold a whole codebase in its head. We're starting with [GAME CONCEPT] and going from there, and I'll tell you straight where it's better than what I'm already paying for and where it isn't. Come hang out in the chat, throw ideas at it, and let's see where it falls over. I spent 12 years as an engineer at Apple, and now I build apps live on stream with AI tools and share the whole process as I go. Join the free community where we're all building together: https://rfer.me/startmyai (My small live cohort opens a few times a year, and you'll hear about it first inside the community.)
