Daily AI CatchupGPT-5.6 Sol Ultra Solves a 50-Year-Old Unsolved Math Problem Using 64 Subagents
OpenAI published an AI-generated proof of a 50-year-old unsolved math problem. GPT-5.6 Sol Ultra spun up 64 subagents and cracked it in under an hour — and OpenAI is temporarily removing the 5-hour usage restriction for Plus, Pro, and Business plans and resetting current usage for everyone.
Why it matters
💻 Developer · 64 parallel subagents solving a genuinely unsolved problem in under an hour is a striking demonstration of Sol Ultra's orchestration mode — worth testing on your hardest unsolved internal problem, even outside math.
📦 Product · Temporary removal of usage caps is a real opportunity to stress-test Sol Ultra at full capacity before limits return — worth prioritizing this week if you've been rationing usage.
🎨 Design · No direct design impact — this is a pure capability demonstration.
📈 Business · Solving genuinely open problems (not just benchmark tasks) is a meaningful capability signal worth tracking for any long-horizon bet on frontier model progress.
🤔 Just Curious · OpenAI's newest AI spent under an hour — using 64 separate AI "helpers" working together — to solve a math problem that had stumped human mathematicians for 50 years.
Try this: Usage caps are temporarily lifted for Plus, Pro, and Business plans — a good window to stress-test Sol Ultra on your hardest unsolved internal problem.
