My initial takeaway is that GPT-6 is mostly a lower cost win, for Luna. GPT-6 Max is an upgrade on intelligence too, but its mostly a cost play (which is great, not complaining).

Overall, I expect for most people think the winner of today was Anthropic. I personally am preferring Opus 5.5 at medium over GPT-6 Sol Max, in very very early tests. Similar price range, more capability.

But competiton is great, these are solid releases by OpenAI today.

Those two reasoning efforts are for entirely different classes of problems. I'd compare Opus Medium vs Sol High.
