We’re publishing another update to OpenAI Problem #130#: computing the exact discrete Fourier transform below n log n.
Our paper now incorporates the all-length bound:
T(n) = O(n(log n)^(1−δ)), with δ = 0.0007547360.
That’s 10.34 times the exponent saving of δ = 7.3×10⁻⁵ in our previous announcement.
The stronger Fourier result comes from Jacob Sussman’s five-stage framework and Chafik Boukhalfa’s improved construction, building on @OpenAI, @0xdoug, @RohanArun, @SJ_Swapnil_Jain and the wider community.

Today I’m launching AI IQ — frontier AI models, scored on the human IQ scale.
Instead of endless leaderboard tables, AI IQ shows:
• Where models land on the IQ bell curve
• How frontier IQ is changing over time
• How models compare on IQ and EQ
• What intelligence costs in practice
GPT-5.5, Claude Opus 4.7, Gemini 3.1, Grok 4.3, Kimi K2.6, Qwen3.6, DeepSeek V4, Muse Spark, and more.
Link in the first reply. Curious which chart surprises you most.
