Our Commentary ​

DevDay is always a whirlwind, and 20+ announcements is just... a lot. GPT-6 Astra is obviously the headliner, but I'm genuinely curious about the smaller tools and API updates. Sometimes those are the ones that quietly change how we build. We're seeing OpenAI really push the envelope on what's possible, and it's both exhilarating and a little overwhelming to keep up.
