🇹🇼 OpenAI Astra評測:2000美元解開10道數學懸案
OpenAI Astra是Sam Altman團隊下一代旗艦模型的內部代號,這次不是刷新聊天測試分數,而是直接解開10道人類數十年沒人解出的數學與理論電腦科學難題,而且只花了大約2000美元的運算成本。這是AI從「做題」進化到「做研究」的重要指標,也是本週最熱門的AI話題。
OpenAI Astra是什麼?
Astra是OpenAI下一代旗艦模型的內部代號。2026年8月1日,OpenAI公布Astra解出10道公開懸而未決的數學問題,包含自1999年就無人解開的「非sofic群」顯式構造問題。
Astra解出哪些數學難題?
Astra推翻了Connes關於von Neumann代數的剛性猜想、證明了Ehrhart體積猜想,並解開Erdős問題集裡的3道題目,包括多色Ramsey數的183號問題,範圍橫跨高維球體堆積、球面編碼、算術電路複雜度與量子平行重複等領域。
為什麼2000美元很關鍵?
OpenAI表示以Sol API的費率計算,找出全部10道題目的解答大約只花2000美元運算成本——相對於這些成果的研究價值,這筆錢幾乎可以忽略不計,代表AI做原創研究的門檻正在急速下降。
Astra的數學證明可信嗎?
可信度才是關鍵。OpenAI沒有只丟出答案了事,而是用Lean這套形式證明語言把每個證明寫成機器可驗證的程式碼,並公開在GitHub上,附上一份249頁的手稿說明完整推導過程,讓數學家能逐行檢查邏輯是否成立。
小克實測心得
身為工具部落客,我沒辦法親自驗證249頁的Lean證明,但這次跟過去AI宣稱「解決難題」不同的是——OpenAI直接把可驗證的形式證明公開,這是比較誠實的作法,也讓外部數學家能挑戰。如果這些證明真的站得住腳,OpenAI Astra會是繼AlphaFold之後,AI最接近「真正做研究」的一次示範。但要注意:目前只是內部模型的展示,離正式發布的Astra還有一段距離,功能與時程都可能改變。

🇺🇸 OpenAI Astra Review: AI Solves 10 Math Problems for $2K
OpenAI Astra just did something no chatbot benchmark can capture: an internal version of OpenAI's next flagship model solved 10 genuinely open math and theoretical computer science problems — for about $2,000 in compute. This is the AI story everyone is talking about this week, because it marks a shift from AI acing tests to AI producing original research.
What is OpenAI Astra?
Astra is the internal codename for OpenAI's next major model. On August 1, 2026, OpenAI announced that an internal Astra build had solved 10 previously unsolved problems in mathematics and theoretical computer science, including the first explicit construction of a non-sofic group — a question open since 1999.
Which math problems did Astra solve?
Astra disproved Connes's rigidity conjecture on von Neumann algebras, proved Ehrhart's volume conjecture, and resolved three problems from Paul Erdős's open-problem catalog, including problem 183 on multicolor Ramsey numbers. Other results span sphere packing, spherical codes, arithmetic circuit complexity, and quantum parallel repetition.
Why does the $2,000 price tag matter?
OpenAI estimated it cost roughly $2,000 in Sol API compute to find all ten solutions — a trivial sum against the research value if the results hold up. That price point is the real headline: it signals the cost of AI-driven original research is collapsing fast.
Can we trust Astra's math proofs?
Verifiability is what separates this from past hype. OpenAI did not just publish answers — it wrote each proof in Lean, a machine-checkable formal proof language, and posted the code on GitHub alongside a 249-page manuscript so mathematicians can audit every step of the logic.
Kit's honest take
I cannot personally verify 249 pages of Lean proofs, but the fact that OpenAI released machine-checkable formal proofs instead of just claiming victory is the responsible move — it invites outside mathematicians to try to break it. If the proofs hold, OpenAI Astra would be one of the clearest demonstrations yet of AI doing actual research, not just retrieval. Keep in mind this is still an internal preview, not the shipped Astra model — capabilities and timeline for the public release remain unconfirmed.

常見問題 FAQ
OpenAI Astra是正式發布的產品嗎?
不是,目前是OpenAI下一代模型的內部展示,用來預告即將推出的Astra能力,正式版本與時程尚未公布。
Astra解數學題花多少錢?
OpenAI估計以Sol API費率計算,找出全部10道題目解答約花費2000美元運算成本。
這些數學證明有經過驗證嗎?
OpenAI用Lean形式證明語言撰寫並公開在GitHub,機器可自動檢查邏輯正確性,並附上249頁手稿供數學家審查。
Astra解決的問題有哪些領域?
涵蓋非sofic群構造、von Neumann代數剛性猜想、Ehrhart體積猜想、Erdős多色Ramsey數、球體堆積、算術電路複雜度等數學與理論電腦科學題目。
