LisanBench estimated the output tokens alone would cost about $6.5 million at consumer prices, with total costs possibly reaching $10 million to $40 million. The achievement drew criticism from mathematicians Tristan Buckmaster and Levent Alpöge over data usage, which OpenAI denied but said it 'cannot rule out that de-identified data derived from their usage of our products helped improve our models.'", "body_md": "Math is hard. And, apparently, expensive.\n\nOn Tuesday, OpenAI said its agents had [solved the Navier-Stokes equations](https://www.businessinsider.com/navier-stokes-millennium-prize-problems-2014-10), a 90-year-old set of mathematical formulas that can predict how liquids and gases move. It's so complicated that the Clay Mathematics Institute has offered a [$1 million prize](https://www.businessinsider.com/millennium-prize-problems-million-dollar-prize-2017-12) to any mathematician who finds the solution.\n\nOpenAI said that finding the solution required a lot of resources. Its coordinating AI agents sent 2.7 million messages while working on the proof. The effort involved about 10,000 concurrent agents and reached a resolution after 88 hours. Verification took another 17 hours.\n\nSuch intensive use of AI doesn't come cheap. In a post on X, LisanBench, an LLM benchmark evaluator, estimated that the output tokens alone would cost about $6.5 million at OpenAI's average consumer price. Including the far larger volume of input tokens, the post estimated the total could reach $10 million to $40 million.\n\nOpenAI CEO Sam Altman replied, joking that AI was a bubble.\n\nOpenAI's announcement that it [solved the age-old mathematics problem](https://www.businessinsider.com/openai-navier-stokes-math-breakthrough-drama-2026-9) was celebrated within the AI industry. It's also been widely criticized after two mathematicians — Tristan Buckmaster and Levent Alpöge — raised questions about how OpenAI used their related research data to train its models.\n\nOpenAI denied direct access to their work, but said that it \"cannot rule out that de-identified data derived from their usage of our products helped improve our models.\"\n\nThe company didn't immediately respond to a request for comment from Business Insider.", "url": "https://wpnews.pro/news/it-took-openai-s-agents-130-billion-tokens-to-crack-a-90-year-old-math-problem", "canonical_source": "https://www.businessinsider.com/openai-math-problem-solved-tokens-cost-altman-2026-9", "published_at": "2026-09-09 15:55:21+00:00", "updated_at": "2026-09-09 16:18:07.775947+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-agents", "ai-research"], "entities": ["OpenAI", "Sam Altman", "LisanBench", "Tristan Buckmaster", "Levent Alpöge", "Clay Mathematics Institute", "Business Insider"], "alternates": {"html": "https://wpnews.pro/news/it-took-openai-s-agents-130-billion-tokens-to-crack-a-90-year-old-math-problem", "markdown": "https://wpnews.pro/news/it-took-openai-s-agents-130-billion-tokens-to-crack-a-90-year-old-math-problem.md", "text": "https://wpnews.pro/news/it-took-openai-s-agents-130-billion-tokens-to-crack-a-90-year-old-math-problem.txt", "jsonld": "https://wpnews.pro/news/it-took-openai-s-agents-130-billion-tokens-to-crack-a-90-year-old-math-problem.jsonld"}}
