猜测：OpenAI 砍掉 Astra 是为给更强的 Bel 级模型让路
一种解读认为，与其赶工 Astra 去压 Opus，不如把算力留给内部更强的新模型，同时向监管展示安全姿态。
What I think happened is that OpenAI basically “cleared the distractions out of the way.” Spending too much time on GPT-6.1 Astra right now may simply not be worth it if that same effort can go into the much more powerful Bel-class systems instead. From an engineering perspective, it makes more sense to focus on the thing that could genuinely shake Anthropic’s entire lineup rather than ship a faster model just to beat Opus. Because let’s be real, Fable 5.5 is sitting there waiting to bury OpenAI if they don’t respond hard enough by December. And strategically, the sequence makes sense: tell regulators you’re taking safety extremely seriously, spend that time shaping something much more powerful internally, then ship it once it’s actually safe enough. Everyone wins. And this lines up with something else I’ve heard for a while now: OpenAI has an internal model that makes the current Astra look like a weak little silicon baby by comparison.
