Which AI Model for Math and Quantitative Reasoning in 2026
If the math problem is genuinely hard — the kind where a wrong step in line three quietly poisons the answer in line fourteen — the default pick in 2026 is o3. It is the most stable model we have for long chains of deduction and the most willing to catch its own errors. Gemini Deep Think is the cost-aware quantitative pick, especially when you need to reason across a long document or many tables. DeepSeek R1 is the budget option that punches well above its price tier on competition-style problems and on legible scratch work. Claude Opus 4.7 with extended thinking is the right call when math is embedded in a longer analytical narrative, or when you need a million-token window with disciplined step-by-step reasoning. 4Models compared across 7 capability dimensions How We Evaluated This is a working buyer's matrix, not a leaderboard. We focused on the dimensions that actually predict whether a model will get a hard quantitative problem right and whether a careful reader will be able to trust the answer. The seven dimensions in the matrix are: Context window — how much math you can stuff in, including problem statements, reference material, prior steps, and data tables. Multi-step deduction stability — whether the model can sustain a long chain of reasoning without drifting, swapping signs, or losing a constraint introduced ten steps earlier. Symbolic manipulation — how reliably it handles algebra, calculus, combinatorics, and proof-style work without "looks plausible" hand-waving. Self-verification behavior — whether the model checks its own work, substitutes back, sanity-checks units, or flags uncertainty rather than confidently producing the wrong number. Showing work clearly — whether the output is a legible argument a human can audit, not a wall of dense notation. Latency — how long you wait for a hard problem. Reasoning models are slow by design; we treat this as a factor, not a deal-breaker. Cost tier — relative price for a representative hard-math turn. Honesty disclaimer. AIME, USAMO, MATH, GPQA Diamond, and FrontierMath are real public benchmarks with published results from model providers and independent researchers. Those numbers move with every model revision, and we will not quote specific percentages in this post. Where prose references a benchmark, we name it and say results are published by the provider or by independent evaluators — no fabricated scores. Capability columns are qualitative buckets: Best-in-class, Strong, Adequate, Traili...
'It is incredible': How AI is transforming mathematics - Nature
Liam Price has no formal training in mathematics and has yet to attend university, but last month, he managed to break new ground in mathematical research — with the help of ChatGPT.AI is threatening science jobs. Which ones are most at risk?From his home in southwest England, Price got the popular artificial-intelligence tool to solve what is known as Erdős problem #1196, one of more than 1,000 puzzles that Hungarian mathematician Paul Erdős (1913–1996) collected throughout his life. Unlike other AI-generated solutions to mathematical problems, this one used a strategy that surprised specialists (B. Alexeev et al. Preprint at arXiv https://doi.org/q6p7; 2026).Posting on the social-media site X, mathematician Jared Duker Lichtman at Stanford University in California drew an analogy with chess. It was, he wrote, as if AI had discovered an opening no one had thought of before because of “human aesthetics and convention”.This is one of the more remarkable examples in a string of successes for AI in mathematics. Researchers in academia and at AI companies have been making a major push to see how far the systems can go. Computers are now contributing not just brute-force calculations, but also the type of logically sound reasoning that has been the province of mathematicians since Euclid more than 2,300 years ago.In many cases, advances have come from systems that are based on general-purpose large language models (LLMs), such as GPT, Gemini and Claude, without any special mathematical training. And — as with many areas of AI — the progress has been astoundingly fast.The systems are still mostly rehashing techniques they absorbed from the existing literature, and that was the case with some of the solutions to other Erdős problems that Price first achieved with his collaborator, Kevin Barreto, a mathematics undergraduate student at Cambridge University, UK.Artificial intelligence has proposed an unusual solution to a puzzle posed by Hungarian mathematician Paul Erdős.Credit: George CsicseryBut in cases such as Erdős problem #1196, mathematicians have started to spot glimpses of original ‘thought’ in the models’ outputs — with the tools making surprising connections between subfields. “It is incredible,” says Sébastien Bubeck, a mathematician at OpenAI in San Francisco, California. “A year ago, people thought maybe there would be some fundamental obstruction — that LLMs could never go beyond their training data.”Bubeck and others now think that it is only a matt...
BBC Audio | More or Less | Erdos Problem 1196: Can AI now solve maths ...
Since the end of last year, AI has been providing solutions to a number of novel maths problems, but Problem 1196 is the first to raise eyebrows within the mathematical community.
The million-dollar math problem hardly anyone is trying to solve
He unexpectedly helped to solve a problem in pure math, but to this day the origin of the connection remains totally obscure.
