What sort of maths are LLMs good at?
• In August 2026, OpenAI's LLMs solved 10 major math problems, including a non-sofic group and a superexponential Ramsey number lower bound.
• LLMs excel at finding counterexamples and examples, often via brute-force trial and broad mathematical knowledge.
• Finding a counterexample depends on context; existential statements can be examples or counterexamples.
• LLMs likely rely on exploring vast search trees, lacking humans' ability to prune unfruitful paths efficiently.
• Future breakthroughs depend on LLMs developing 'mathematical nose' for novel, deep insights beyond brute force.#AIinMath #MathBreakthrough #LLM
