复盘 OpenAI 用 Sol/Terra/Luna 命名拖时间为 Astra 争取窗口
作者认为 5.6 的三档命名是营销烟雾弹：Terra 只是撑场面，让 Sol 被当成对标 Fable 的答案，为 Astra 争取几个月。
aha! with the benefit of hindsight, i just figured out openai’s marketing team seriously cooked hard with their gpt 5.6 release let me reverse GTM what happened for you at that time, fable was already released and people were loving it. but openai knew astra was far from being ready if people ask “what’s your answer to fable” and they say “we are a few months behind”, it’ll damage their brand so instead of doing the typical 2-tier “gpt 5.6” and “gpt 5.6 mini”, they artificially created a 3-tier system with a new naming scheme - sol, terra, luna pretty sure terra was not even originally planned but added last minute to make this plan work. in their release announcement, terra was said to be the same performance as gpt 5.5, while sol is a step function better this created a perception that sol was openai’s fable equivalent. if you still remember, most of the reviews back then were comparing sol with fable. many of which even said sol was better that bought so much time for openai to catch up without being seen as falling behind and now that astra is here, terra immediately got killed in the 6 series because it was never real! everything made sense now, and it’s absolutely brilliant
