I really can't tell the difference at this point between Mythos 5.0 and GPT 5.6.

I mean, primarily because neither one of them has been released yet and I've had no chance to use them, but still.

@tunguz Mythos is the one that feels to dangerous to release. Like GPT-2.

@tunguz Şu an GPT-5.5 Instant ve GPT-5.5 Thinking sürümleri var. 5.6 çıktığı zaman ikisi de aynı anda mı güncellenecek? Yani GPT-5.6 Instant ve GPT-5.6 Thinking olarak mı devam edecek? 🤔

@tunguz Hot Take: They're the same thing.

@tunguz Does mythos still pretend to be your parent(s) and tell you to go to bed ever 5 seconds?

@tunguz When the frontier models start blurring together, the real differences move to taste and tooling.
