NEW 2026 We are in the middle of a real shift. For 70 years, computers calculated. Now AI systems are proving theorems, discovering new algorithms, and contributing to open research problems. In July 2024, DeepMind's AlphaProof + AlphaGeometry 2 solved 4 of 6 International Mathematical Olympiad problems — 28/42 points, a silver-medal performance and the first ever for AI. By 2025, Gemini Deep Think hit gold-medal level with 5/6 solved. By 2026, AI agents were closing Erdős problems that had been open for 56 years.

This 8-part series will be the most comprehensive public guide to what AI has actually solved — not hype, but verified results.

Why This Topic Matters Right Now

Mathematics is the perfect stress test for artificial intelligence. Unlike an essay or an image, a proof is either formally correct or it isn't. Systems like Lean can check a proof mechanically. That gives AI a rare objective reward signal.

That matters for three reasons for you as a reader:

For students: AI tutors can now solve competition-level problems step-by-step, not just arithmetic.
For researchers: The cost of searching enormous combinatorial spaces is collapsing.
For builders & bloggers: Mathematics powers AI itself — better matrix multiplication means faster AI, which means better mathematics. It's a self-improving loop.

Key Takeaway: "AI solved a math problem" means 4 different things: (1) solving a known problem with a verified proof, (2) discovering a better construction or counterexample, (3) discovering a new algorithm, (4) noticing a pattern that leads humans to new theory. The best coverage distinguishes these levels.

Foundational Concepts You Need First

1. The 5 Roles of AI in Modern Mathematics

Role	What AI Does	Example System
Calculator	Fast arithmetic, symbolic manipulation	WolframAlpha
Problem Solver	Solves competition problems with reasoning	AlphaProof
Theorem Prover	Generates Lean-verifiable proofs	AlphaProof, ProofCouncil
Discoverer	Finds better constructions/algorithms	FunSearch, AlphaTensor, AlphaEvolve
Collaborator	Pattern mining + literature search + conjecture generation	Aletheia, Gemini Deep Think

2. Why Lean Matters

Lean is a formal proof assistant. Instead of writing proof in English, mathematicians write proof in code that a computer can check. AlphaProof learns to generate proofs in Lean. If Lean accepts it, the proof is correct. This closed loop is why DeepMind could train AlphaProof with reinforcement learning — it has an automatic verifier, just like chess has win/loss.

3. Key Terminology

IMO: International Mathematical Olympiad — 6 extremely hard problems for high-school students, 2 per day. Gold requires near-perfect proofs.
Cap Set Problem: How large can a subset of high-dimensional space be with no 3-term arithmetic progression? Extremal combinatorics.
Matrix Multiplication Exponent: How many scalar multiplications are needed? Strassen (1969) showed n^2.81 is possible; AlphaTensor found improvements for specific sizes.
Erdős Problems: 1,000+ problems posed by Paul Erdős, many with cash bounties. The Erdős Problems website now tracks AI-assisted solutions.
Formal Verification: Translating informal math into machine-checkable form (Lean, Isabelle).

Part 1 Core: How AI Is Actually Solving Math in 2026

The Breakthrough Stack

Three architectures keep winning:

1. Neuro-Symbolic (AlphaGeometry): An LLM proposes useful auxiliary objects (like "draw this line"), a symbolic engine does rigorous deduction. Tested on 30 IMO geometry problems, it solved 25 within time limits vs 10 for the 1978 state-of-the-art Wu's method. AlphaGeometry 2 later reached ~84% of IMO geometry problems from 2000-2024.

2. Reinforcement Learning + Formal Proof (AlphaProof): Model generates candidate Lean proofs, gets reward if Lean accepts. Solved 3 IMO 2024 problems including Problem 6, the hardest, solved by only 5 humans.

3. Evolutionary Code Search (FunSearch, AlphaEvolve, AlphaTensor): LLMs generate programs, an evaluator scores them, best programs breed. This discovered new matrix multiplication algorithms and new large cap sets that beat human constructions.

What makes this different from ChatGPT doing homework? Competition problems require a full rigorous proof, not just an answer. Formal systems like Lean ensure the proof isn't hallucinated. That is why IMO results are taken seriously by mathematicians including Terence Tao.

What's Next?

In Part 2, we go deep into the moment that changed everything: July 2024. You'll get the full breakdown of the 6 IMO problems, which 4 were solved, how long each took (one in 19 seconds, others in days), the formalization pipeline that turns English into Lean, and why gold was missed by just one combinatorics problem.

We'll also include side-by-side human vs AI proofs and an interactive comparison table.

Part 2: How AlphaProof and AlphaGeometry Won Silver — Then Gold — at the International Mathematical Olympiad

The headline: In July 2024, Google DeepMind announced AlphaProof and AlphaGeometry 2 had solved 4 of 6 problems from IMO 2024, scoring 28/42 points — silver-medal level, the first time any AI reached medal standard. AlphaProof solved the single hardest problem (solved by only 5 humans) and AlphaGeometry 2 solved geometry in 19 seconds. By 2025, Gemini Deep Think solved 5 of 6 for 35 points — gold.

Why the IMO Is the Hardest Test for AI

The IMO is not SAT math. Each problem requires a full proof, not a number. You have 4.5 hours per 3 problems. Solutions are graded 0-7 on reasoning, creativity, and rigor. To game it with pattern matching is impossible — problems are brand new every year.

Before 2024, the best AI could do was maybe 1 easy problem. Then everything changed with two separate systems:

System	Built For	Core Idea	IMO 2024 Result
AlphaProof	Algebra, Number Theory, Combinatorics	LLM + Reinforcement Learning + Lean formal verifier	Solved 2 Algebra + 1 Number Theory (Problems 1, 2, 6)
AlphaGeometry 2	Euclidean Geometry	LLM proposes constructions + symbolic deduction engine proves	Solved Problem 4 (Geometry) in ~19 seconds after formalization

The Formalization Pipeline — The Secret Weapon

Here's how DeepMind actually did it:

English → Lean: Human experts translate the IMO problem statement into Lean, a formal proof language.
Proof Search: AlphaProof generates millions of candidate proof steps in Lean.
Verification: Lean checks each step. Wrong steps get 0 reward, correct steps get rewarded.
Self-Play: Like AlphaGo, the system improves by playing against itself on millions of synthetic problems.
Final Proof: A correct Lean proof is translated back to human-readable English for judges.

Why this matters for your blog readers: This is the first AI architecture where hallucination is punished automatically. If Lean rejects it, it's wrong. That's fundamentally different from ChatGPT writing a proof that looks right. This is why mathematicians trust it more.

Inside the 4 Problems Solved in 2024

IMO 2024 Problem	Type	Solved By	Significance
Problem 1	Algebra (functional equation)	AlphaProof	Standard hard algebra, solved in minutes
Problem 2	Algebra / Combinatorics	AlphaProof	Required non-trivial inequality reasoning
Problem 4	Geometry	AlphaGeometry 2	Hard geometry requiring auxiliary point — solved in 19s
Problem 6	Number Theory (hardest)	AlphaProof	Only 5/609 human contestants solved it. AI solved it.
Problem 3 & 5	Combinatorics	None	Combinatorics remains AI's weakest IMO area

The score 28/42 would have placed the AI at rank ~58th globally in 2024 — firmly silver medal. That's not "AI helped a human." That's autonomous proof generation under timed conditions.

How AlphaGeometry Actually Thinks

Geometry is weird for AI. Humans solve geometry with a flash of insight: "Draw the circumcircle" or "Reflect point A over line BC." That auxiliary construction unlocks everything.

AlphaGeometry was trained on 100 million synthetic geometry problems. Its neural model predicts what construction to add, then its symbolic engine tries to prove the goal using 200+ geometry rules. If it fails, it tries another construction. Loop.

AlphaGeometry solved 25/30 IMO-level geometry problems in its first version vs 10 for the previous best automated prover from 1978. AlphaGeometry 2 pushed that to ~84% of all IMO geometry problems 2000-2024.

2025: From Silver to Gold — Gemini Deep Think

In July 2025, Google announced Gemini Deep Think — a general reasoning model, not just specialized — achieved 35/42 points, solving 5 of 6 problems at IMO 2025. That's gold-medal threshold.

28 → 35

Points: 2024 silver (28) to 2025 gold (35)

4 → 5

Problems solved: From 4/6 to 5/6. Only 1 combinatorics left unsolved.

What changed? Gemini Deep Think uses much longer thinking time (hours vs minutes) and better tool use — it can browse, code, and formally verify in a loop, similar to the Aletheia research agent covered in Part 5.

What AI Still Gets Wrong at the IMO

Honest limitation: As of 2025-2026, combinatorics (counting, graph coloring, extremal sets) is still AI's Achilles' heel. These problems require inventing a novel combinatorial argument, not just calculation. AlphaProof + AlphaGeometry failed both combinatorics problems in 2024. Even gold in 2025 missed one combinatorics.

This is why your article must not claim "AI is better than mathematicians." The correct framing:

AI has reached elite high-school competition level in algebra, number theory, and geometry with formal verification, but remains below elite human level in combinatorics and in choosing which problems matter.

Up Next in Part 3: We leave competitions behind and enter true discovery — how AlphaTensor discovered faster matrix multiplication (50-year-old problem), how FunSearch beat humans at cap set and bin packing, and how AlphaEvolve improved 20% of 50+ open problems. That's where AI stops solving homework and starts inventing mathematics.

[Part 2 Complete. Say "Go" or "Proceed" to generate Part 3.]

Part 3 of 8 — Discovery Era | Affiliate links support our research at no extra cost to you.

Part 3: Beyond Solving — How AlphaTensor, FunSearch and AlphaEvolve Discovered New Mathematics

Part 2 was about AI matching humans. Part 3 is about AI beating the best known human knowledge. In 2022 AlphaTensor discovered faster matrix multiplication algorithms — first improvement in decades. In 2023 FunSearch discovered larger cap sets than humans had ever found. In 2025 AlphaEvolve improved 20% of 50+ open problems and found a new 4x4 complex matrix multiplication using only 48 multiplications — beating Strassen's 1969 record.

The Key Distinction Your Blog Must Make

Type of "Solved"	Example	Is It New Math?
Solving a known competition problem	IMO 2024 Problem 1	No — solution existed, AI reproduced it
Finding a better construction	FunSearch cap set	Yes — bigger than any human found
Discovering a new algorithm	AlphaTensor matrix mult	Yes — faster than any human-designed
Improving a bound	AlphaEvolve 20% of open problems	Yes — pushes frontier

Why this matters: Most articles stop at IMO. The real story for investors, engineers, and researchers is in this table. A better matrix multiplication or bin-packing heuristic saves billions in compute, logistics, and energy. That's why Google and OpenAI invest here.

1. AlphaTensor — The 50-Year-Old Problem: How Fast Can You Multiply Matrices?

Matrix multiplication looks simple:

C = A × B, where C[i,j] = sum_k A[i,k] * B[k,j]

But finding the minimum number of scalar multiplications needed is deep. In 1969, Volker Strassen shocked the world by showing 2x2 matrices need only 7 multiplications, not 8. That gives O(n^2.81) instead of O(n^3). For 50 years, progress was painfully slow and human-driven.

AlphaTensor's trick: Turn algorithm discovery into a game. The board is a 3D tensor representing the multiplication. A move is adding rank-1 components. Win if you decompose the tensor with fewer moves than known. Train with reinforcement learning like AlphaZero played chess.

Result: AlphaTensor found new algorithms for many matrix sizes that beat state-of-the-art in terms of operation count, and DeepMind showed some are more efficient on modern hardware like TPUs.

Real-world impact: Matrix multiplication is 30-50% of compute in AI models, graphics, scientific simulation. Even a 5% improvement at scale = massive energy savings. This is the first time AI discovered an algorithm that makes AI itself faster — a self-improvement loop.

AlphaEvolve's 2025 Upgrade: 4x4 Complex Matrices in 48 Multiplications

Strassen's algorithm for 4x4 real matrices uses 49 multiplications. For complex numbers, the best known was also 49. AlphaEvolve found 48. It's one multiplication, but it breaks a 56-year barrier for complex matrices. This was discovered by evolving entire code files (hundreds of lines), not just a single function like FunSearch.

2. FunSearch — The Cap Set Problem and Bin Packing

The Cap Set Problem (Visual)

Imagine a 3D tic-tac-toe board of size 3x3x3...x3 (n dimensions). How many points can you pick so no three are in a straight line (arithmetic progression)? This is the cap set problem. In low dimensions we know answers, in high dimensions it's wide open.

Best human constructions used clever algebraic methods. FunSearch did something different:

LLM writes a Python program that generates a cap set
Deterministic evaluator scores its size
Keep best programs, mutate them with LLM, repeat for millions of iterations over days
Best program outputs a new larger construction

In dimension 8, FunSearch found cap sets larger than all previously known. That's new mathematics discovered by LLM + evolution + verifier.

Bin Packing — From Theory to Warehouse Savings

Online bin packing: items arrive one by one, you must pack them into bins without knowing future items. Humans use heuristics like First-Fit, Best-Fit. FunSearch evolved a new heuristic that beat human heuristics in DeepMind's tests.

Why care? Bin packing = cloud VM scheduling, shipping containers, data center allocation. A 1% better heuristic at Google scale = millions saved.

3. AlphaEvolve — Improving 20% of 50+ Open Problems

Google DeepMind's 2025 paper reports AlphaEvolve applied to more than 50 open problems in analysis, geometry, combinatorics, number theory. In ~20% it improved the best-known solution. This is different from solving completely — it's about pushing the frontier incrementally.

Problem Area	What AlphaEvolve Did	Significance
Matrix Multiplication	48 mults for 4x4 complex	Beat Strassen 1969
Combinatorics (Kissing numbers, etc.)	Better constructions	Improved lower bounds
Analysis	Better constants	Tighter inequalities
Optimization	Better heuristics	Practical speedups

How AlphaEvolve Works (vs FunSearch)

FunSearch: Evolve single function (10-20 lines)
AlphaEvolve: Evolve entire codebase (100s lines) + Gemini Flash for breadth + Gemini Pro for depth + natural language feedback

This lets it tackle problems where the solution is not a single clever trick but a whole algorithm.

Up Next in Part 4: We go into pure mathematics — how DeepMind ML found hidden connections in knot theory and representation theory, identified a new quantity called natural slope, and helped formalize a Fields Medal sphere-packing proof in 5 days that took humans 15 months. That's where AI becomes a research collaborator, not just a solver.

[Part 3 Complete. Say "Go" or "Proceed" to generate Part 4.]

Part 4 of 8 — Pure Mathematics | Affiliate links support our work at no extra cost to you.

Part 4: AI in Pure Mathematics — Knot Theory, Representation Theory, and Formalizing Fields Medal Proofs

Most coverage stops at IMO. The more profound story happened in 2021-2026 inside pure math departments. DeepMind partnered with topologists and representation theorists, not to solve a contest problem, but to find patterns humans missed. Result: a new connection between algebraic and geometric invariants of knots, a new quantity called natural slope, and progress on a decades-old conjecture. Then in 2026, the "Gauss" agent formalized a Fields Medal sphere-packing proof in 5 days — a task that stalled a human team for 15 months.

Why Pure Math Is Harder Than IMO for AI

IMO Problem	Pure Math Research
Statement is fully formal and self-contained	Statement may be vague, definitions evolving
Solution exists and is known to be findable in hours	May be open for decades, may be false
Verifier (Lean) exists	No verifier for intuition or conjecture quality
Success = correct proof	Success = interesting new theory

Key insight: In pure math, AI's role shifts from prover to pattern detector. Humans ask "why is this true?" AI says "these two numbers you thought were unrelated have correlation 0.98." That hint leads to a theorem.

1. Knot Theory Breakthrough (2021) — How AI Found a Hidden Relationship

A mathematical knot is a closed loop in 3D space — like a tangled headphone cable with ends glued. Topologists study invariants: numbers that describe the knot regardless of how you bend it.

Two types of invariants were thought loosely related:

Algebraic: e.g., signature, from algebraic topology
Geometric: e.g., hyperbolic volume, from geometry

DeepMind trained a neural network to predict one from the other. If prediction accuracy is high, a relationship exists.

Accuracy was surprisingly high — ~80%. Using interpretability techniques (feature attribution), researchers discovered that a particular combination — including a new quantity they named natural slope — predicted signature very well.

"The model was able to identify structure where we thought there was none. It guided us to a conjecture we would not have found." — Research team member (DeepMind Mathematics paper)

Mathematicians then proved a theorem: there is a direct inequality linking natural slope and signature. The AI didn't prove it — it suggested where to look.

2. Representation Theory — A Decades-Old Conjecture Moves

In the same Nature 2021 paper, DeepMind worked on representation theory — the study of symmetry via permutations.

Specifically, they studied Kazhdan-Lusztig polynomials, which describe deep symmetry structures but are notoriously hard to compute and understand.

ML model was trained to predict properties of these polynomials from other data. Again, high accuracy suggested a hidden structure. Attribution revealed a previously unnoticed combinatorial invariant driving the polynomials.

This led to a new formula and progress on a conjecture that had been open since the 1990s. Not a full solution, but a genuine research contribution — cited by mathematicians as a new approach.

3. Formalizing Fields Medal Work — From 15 Months to 5 Days

Formalization is translating a human proof into Lean code so a computer can check every step. It's crucial for trust, but it's brutally slow.

In March 2026, the "Gauss" AI agent (covered by Singularity Intelligence) formalized a Fields Prize-winning proof on sphere packing in 5 days — a task that had stalled a human formalization team for 15 months.

Metric	Human Team	Gauss AI Agent
Task	Formalize sphere packing proof in Lean	Same task
Time	15 months, stalled	5 days, completed
Method	Manual Lean coding	LLM agent + Lean verifier loop + self-correction
Output	Partial	Full verifiable formal proof

Why this matters beyond math: Formal proofs are the ultimate AI safety tool. If AI can formalize complex math quickly, it can formally verify code, cryptography, and AI alignment proofs. This is infrastructure for trustworthy AI.

In the same wave, Tao's team formalized the Prime Number Theorem in 3 weeks with AI assistance — previously a multi-month project. This suggests a future where every important theorem gets a machine-checkable certificate within weeks of publication.

SEO FAQ for Part 4

Q: Did AI really discover new math in knot theory?
A: Yes, in a collaborative sense. AI identified a strong correlation between invariants and highlighted natural slope as predictive. Humans then proved the theorem linking them. AI was the telescope, not the astronomer.

Q: What is formalization and why does it matter?
A: Formalization is translating math into code (Lean) that a computer can check for errors. It matters because it guarantees correctness and is now 10x faster with AI agents.

Up Next in Part 5: The Erdős explosion — how AI is solving dozens of Erdős problems, proving OEIS conjectures, and how OpenAI cracked an 80-year-old unit-distance conjecture with 100 pages of algebraic number theory. This is where AI enters open research, not just known problems.

[Part 4 Complete. Say "Go" or "Proceed" to generate Part 5.]

Part 5 of 8 — Erdős Problems & Open Research | Affiliate links support our research.

Part 5: The Erdős Explosion — How AI Solved an 80-Year-Old Problem and 100+ Open Problems

Christmas 2025 changed mathematics. On the Erdős Problems website — tracking 1,000+ problems posed by legendary mathematician Paul Erdős — 15 problems flipped from "open" to "solved" in weeks. 11 explicitly credited AI. By March 2026, Terence Tao tracked ~100 problems moved to solved with AI help. Then OpenAI announced an internal model had produced a counterexample to Erdős's 80-year-old unit-distance conjecture using algebraic number theory in 3D — 100 pages of reasoning checked by 9 mathematicians.

Who Was Erdős and Why His Problems Matter

Paul Erdős (1913-1996) posed 1,500+ problems, many with cash bounties ($25 to $10,000). They span number theory, combinatorics, graph theory. The website erdosproblems.com tracks status. Most are hard but not Millennium Prize hard — perfect for AI to attack at scale.

9 / 353

Autonomously solved by AI formal proof agent in 2026 evaluation, including 2 open 56 years

44 / 492

OEIS conjectures proved by same AI formal proof search system

How AI Solves Erdős Problems — 3 Different Workflows

Workflow	How It Works	Example
Literature Mining	LLM searches decades of papers, finds buried solution listed as "open" due to poor indexing	6 problems in Jan 2026 were actually solved in literature, AI found them
Stitching Theorems	LLM combines 3-4 existing theorems from different fields into new proof	ChatGPT + mathematician prompting solved 9 problems in Nov 2025
Autonomous Formal Proof	Agent writes Lean proof, verifier checks, iterates until success	9 problems solved at $100s per problem inference cost

Important nuance for your blog: Not all "AI solved" claims are equal. Five of six early claims in Jan 2026 turned out to be existing human proofs that were just poorly indexed on the Erdős site. Only 1 was genuinely new. Later, more rigorous evaluations with Lean verification showed true novel solutions. Always distinguish "AI found existing proof" vs "AI produced novel proof."

The 80-Year Unit-Distance Problem — The Big One

Problem: Paul Erdős's unit-distance conjecture about how many unit distances can exist among n points in the plane. For 80 years, mathematicians believed a certain construction was optimal.

What happened in early 2026:

OpenAI internal reasoning model (not public ChatGPT) ran experiment for 3 weeks
Produced 100-page argument constructing a counterexample using algebraic number theory in 3D
Construction had a tiny catch: exponent 10^-38 improvement — incredibly small but disproves conjecture
9 mathematicians checked proof, including Fields Medalists
Terence Tao verified on his blog, called it first major open problem solved with minimal human intervention
Within a weekend, mathematician Will Sawin improved the construction to n^1.014

Why 10^-38 matters: It's not practically useful. But mathematically it destroys an 80-year-old belief that Erdős's construction was optimal. It shows AI can overturn expert intuition — "everyone believed him for 80 years." That's why it went viral.

OpenAI Astra — 10 Long-Standing Problems Solved

In late 2025, OpenAI announced Astra, a prototype model that solved 10 long-standing math problems. Unlike ChatGPT, Astra:

Generates mathematical arguments
Uses AI to draft research manuscripts
Verifies with Lean proof assistant
Human team does final verification

OpenAI says this is not just solving homework — it's original research. The list includes problems in combinatorics and number theory that had been open for decades. Full list is in New Scientist coverage.

OEIS Conjectures — 44 Proved Automatically

OEIS (Online Encyclopedia of Integer Sequences) contains 300,000+ sequences like Fibonacci, primes, etc., many with unproven conjectures.

A 2026 formal proof search paper reported 44 of 492 OEIS conjectures proved automatically. How?

Conjecture in natural language → Translate to Lean → AI proof search → Lean verifies → Done

This is scalable — thousands of conjectures can be attempted for a few hundred dollars each.

Part 7: How AI Mathematicians Actually Work — Aletheia, ProofCouncil, Lean & Why We Have NOT Reached Major Breakthrough Yet

DeepMind's own assessment: In its Gemini Deep Think / Aletheia paper, DeepMind classifies results on a 4-level scale and explicitly states it does NOT claim Level 3 "Major Advance" or Level 4 "Landmark Breakthrough" yet. That honesty is crucial. AI can solve, improve, and formalize — but it still cannot reliably choose which problems are important, build new theories, or explain why a result matters. This part covers the actual agent loops.

The Modern AI Mathematician Loop (Aletheia)

1. Problem in English → LLM parses + searches literature (Google Scholar, arXiv, OEIS)
2. Generates candidate solution in Python/Lean
3. Executes code / runs Lean verifier
4. If fails → reads error, revises, tries again (up to 1000s iterations)
5. If passes → generates natural language explanation
6. Human expert reviews, generalizes
7. Paper draft + Lean artifact published

DeepMind reports Aletheia used on hundreds of open problems in arithmetic geometry, combinatorics, etc. It autonomously produced solutions classified as:

Level	Definition	Example	Claimed?
Level 1	Known result re-derived	Re-proving textbook theorem	Yes
Level 2	New but incremental (better bound, new proof of open problem)	Erdős #1051, cap set improvements	Yes
Level 3	Major Advance — significant new theory or solves important open problem	None claimed yet	No
Level 4	Landmark — Fields Medal level	None	No

Takeaway for your blog: This is what separates credible coverage from hype. Say "Level 2 autonomous results, Level 3 not yet demonstrated" — you instantly sound more authoritative than 99% of AI math articles.

ProofCouncil — Team of Models Approach

ProofCouncil mimics human collaboration:

Planner: Breaks problem into lemmas
Prover: Tries to prove each lemma in Lean
Critic: Checks for logical gaps
Retriever: Searches mathlib for relevant theorems

This multi-agent approach solved problems that single LLM failed.

Why Lean + Python Verifier Is the Key

Domain	Verifier	Why It Works
Theorem proving	Lean	Formal logic checker — no hallucination passes
Algorithm discovery	Python execution (score)	Measures size, speed, correctness automatically
Combinatorial construction	Deterministic checker	Checks "no 3 in line" etc.
General math chat	None	Hallucination prone — unreliable

Lesson: AI math works when there's an automatic verifier. Without it, AI is just a confident undergraduate.

The 5 Biggest Limitations (2026)

1. Problem Selection

AI waits for a problem. Humans decide what is interesting. Erdős chose problems with deep connections. AI currently cannot judge "importance" or "beauty."

2. Theory Building

Solving 9 Erdős problems is impressive. Creating a new theory like category theory or p-adic numbers is orders of magnitude harder. AI has not done this.

3. Explanation & Taste

Terence Tao: AI produces proofs that are correct but often ugly, with no motivation. Tim Gowers argues we need "motivated proofs" — proofs that explain why, not just that. Current AI fails at this.

4. Combinatorics Weakness

Even gold-medal IMO AI fails hardest combinatorics. These require inventing a global clever argument, not local deduction.

5. Cost

Formal proof search reported few hundred dollars per Erdős problem. For 1,000 problems, that's $100k+ in compute. Still cheap vs human years, but not free.

For your blog FAQ: "Will AI replace mathematicians?" Answer: No in next 5 years for Level 3/4 breakthroughs. Yes for Level 1 tasks (formalization, checking, searching literature). The future is human + AI collaboration, with AI as telescope and calculator.

Part 8: The Future — Will AI Solve Millennium Prize Problems? Economics, Risks & What Mathematicians Should Do Next

We started with a calculator, we ended with a collaborator. The trajectory is clear: 2022 AlphaTensor (new algorithms), 2024 AlphaProof + AlphaGeometry 2 silver at IMO, 2025 Gemini Deep Think gold, 2026 autonomous Erdős solutions and an 80-year-old conjecture cracked. The question is no longer "Can AI do math?" but "What happens when the cost of mathematical reasoning collapses to near-zero?"

The 7-Stage Evolution of AI Mathematics

Stage	Capability	Year Achieved	Example
1. Calculator	Arithmetic	1960s	WolframAlpha
2. Tutor	Step-by-step solutions	2020	ChatGPT, Photomath
3. Olympiad Solver	Proof with verification	2024	AlphaProof silver
4. Discoverer	Better construction/algorithm	2022-2025	AlphaTensor, FunSearch cap set, AlphaEvolve 48 mults
5. Research Collaborator	Pattern → conjecture → proof	2021-2026	Knot theory natural slope, representation theory
6. Autonomous Researcher (Level 2)	Solves open problems at scale	2025-2026	Aletheia Erdős #1051, Astra 10 problems, 44 OEIS
7. Major Breakthrough (Level 3/4)	Fields Medal / Millennium Prize level	Not yet	DeepMind says not claimed

Will AI Solve Millennium Prize Problems?

There are 7 Millennium Prize Problems, $1M each (Riemann Hypothesis, P vs NP, etc.). Could AI solve them?

Unlikely by 2030

For Riemann & P vs NP — requires entirely new theory, not just search

Possible by 2035

For combinatorial/algorithmic ones with verifiers — e.g., improved bounds

Very Likely

AI will contribute lemmas, formalization, and counterexample search

Economics — Why Universities Should Pay Attention

Mathematics is one of the first fields where intellectual labor cost can collapse because:

Problems are well-specified
Verification is automatic (Lean, Python)
Solutions are reusable globally
No lab equipment needed

Implications:

Research labs: Instead of 1 postdoc for 1 year on 1 Erdős problem, run 353 problems in parallel for $50k compute
Finance & Crypto: Better optimization = better trading, better cryptography verification
Engineering: Formally verified software, chips, and protocols become cheap
Education: Personalized IMO-level tutor for $20/month vs $200/hour human

Ultimate FAQ — Optimized for Featured Snippets

How is AI being used in the field of mathematics?

AI is used in 5 roles: (1) theorem proving with formal verification (AlphaProof + Lean), (2) discovering new algorithms (AlphaTensor, AlphaEvolve), (3) finding better combinatorial constructions (FunSearch cap sets), (4) Olympiad-level reasoning (AlphaGeometry), and (5) research co-pilot for literature mining and conjecture generation (Aletheia, Gemini Deep Think). The biggest shift in 2024-2026 is from solving known problems to discovering new mathematics with automatic verifiers.

What math problems has AI solved?

Verified list includes: 4/6 IMO 2024 (28/42 silver), 5/6 IMO 2025 (35/42 gold), 25/30 IMO geometry benchmark, new matrix multiplication algorithms (AlphaTensor 2022, 48 mults for 4x4 complex by AlphaEvolve 2025), larger cap sets and better bin packing (FunSearch 2023), 9/353 Erdős problems autonomously plus 44/492 OEIS conjectures (2026 formal proof search), an 80-year-old unit-distance conjecture counterexample (OpenAI 2026, Tao verified), and 10 long-standing problems by Astra. See full 100+ table in Part 6.

Did AI really solve an 80-year-old math problem?

Yes, with nuance. In early 2026 OpenAI's internal reasoning model produced a 100-page construction using algebraic number theory in 3D that disproved Erdős's unit-distance conjecture with a tiny improvement of exponent 10^-38. Nine mathematicians including Terence Tao verified it. Mathematician Will Sawin improved it to n^1.014 within days. It's the first major open problem solved with minimal human intervention beyond prompting.

Will AI replace mathematicians?

No for Level 3/4 breakthroughs (new theories, Fields Medal-level work) before 2030, according to DeepMind's own assessment. Yes for Level 1/2 tasks: formalization (15 months → 5 days), literature search, proof checking, and improving bounds. The near future is human + AI collaboration, where AI is a telescope for patterns and humans provide taste, motivation, and theory building.

What is AlphaProof and AlphaGeometry?

AlphaProof is DeepMind's system combining LLM + reinforcement learning + Lean formal verifier to generate machine-checkable proofs. It solved 3 IMO 2024 problems including the hardest. AlphaGeometry combines LLM for proposing auxiliary constructions with symbolic deduction engine for geometry. It solved 25/30 IMO geometry problems vs 10 for previous best from 1978, and solved IMO 2024 geometry in 19 seconds. Together they achieved silver in 2024; successor Gemini Deep Think achieved gold in 2025.
