Good morning, Tech Family! ☀️ It's Saturday! No plans for today yet. Maybe it's time to step away from the screen and touch some grass for the first time in a while. 😂🌱 What are you all up to this weekend?

Fable is incredibly powerful, and its performance is seriously impressive. By the time Astra arrives, Fable might have already established a firm grip on the AI coding landscape. The real question is: Can Astra rise to the challenge and compete with Fable? The next battle between OpenAI and Anthropic is going to be fascinating.

Good morning, Tech Family! ☀️ I've been feeling under the weather for the past couple of days and barely had the energy to check X. But I think I'm finally getting back to normal today! ☕️ I was half-expecting some big GPT news while I was away, but apparently nothing major

What do you all think about the potential evolution of Astra 6.2 and Fable 5.5? 👀 The jump to Astra 6.2 is particularly interesting to me. If OpenAI is truly confident in what they've built, wouldn't they be able to ship it without worrying too much about what Anthropic does
