Honestly this chart makes me more bullish on GPT 5.4 Pro than anything else.
People are focusing on Mythos looking strong, but what stands out to me is how well 5.4 Pro already stacks up on the overlap we actually have. GPQA is basically a tie at 94.4 vs 94.5. BrowseComp is a win for GPT 5.4 Pro at 89.3 vs 86.9. Yes, Mythos is ahead on Humanity’s Last Exam, 56.8 vs 42.7 without tools and 64.7 vs 58.7 with tools, but the bigger point is that 5.4 Pro is already this competitive right now.
So if GPT 5.4 Pro is already THIS COMPETITIVE here, then Spud Pro, the next OpenAI flagship, is guaranteed to beat Mythos. This chart makes OpenAI look extremely close before its next real jump, and once that next jump lands I do not think Mythos stays ahead.
