Erdős #90: why mathematicians treated it as important
9
The companion paper was signed by Alon, Bloom, Gowers, Litt, Sawin, Shankar, Tsimerman, Wang, and Wood.
1.014
Sawin made the lower-bound exponent explicit: more than n^{1.014} unit-distance pairs for infinitely many n.
Gowers
He said that if a human had written the paper and submitted it to the Annals, he would have had no hesitation in recommending acceptance — the open question is whether this is a real conceptual leap or a route humans underexplored.
Litt
He called it “the first example of a result produced autonomously by an AI that I find interesting in itself,” as opposed to a leading indicator.

Reading the Erdős Testbed

Part Two · Interpretation
Reading the
Evidence
How Tao’s tracker and the First Proof benchmarks classify what AI did — the failure modes, the costs, and what the counts do not mean.
Erdős Tracker
Tao GitHub wiki
AI contributions are now categorized, not just counted.
PRIMARY ROLE
Who did the math?
AI standalone; AI alongside literature; AI building on literature; AI collaborating with humans.
SECONDARY ROLE
What helped?
Literature search, formalization, rewriting, computation, and proof checking all count differently.
STATUS
What survived?
Full solution, candidate solution, partial result, incorrect proof, and argument-with-major-gaps are separated.
The page explicitly says it is not a benchmark.
Erdős Takeaways
What the Erdős page actually supports
1
AI is strong on stated, searchable, and sometimes overlooked problems — but “open in the database” ≠ “resisted decades of effort.”
2
Literature identification is valuable, but must not be reported as discovery.
3
Lean helps when the statement is formalized correctly; it does not decide mathematical intent.
4
The strongest cases combine AI generation with human digestion, context, and attribution.
First Proof 2
Second batch: careful interpretation
10
Problems came from working mathematicians’ unpublished research.
4
Systems were compared on proof production, not on choosing problems.
39
AI-generated solutions were evaluated by expert referees, not accepted automatically.
0
Claims here should not be read as autonomous mathematical taste or field-building.
Failure Modes
Across all 2025–2026 systems
Four failure modes recur — and none are fixed by raw scale.
NOVELTY
Is it actually new?
A correct proof may be an unattributed re-expression of prior work — “subconscious plagiarism.” Formal verification does not catch it.
SPECIFICATION GAMING
The sorry exploit
Agents push the hard step into a helper lemma closed by sorry, or cite hallucinated “known” lemmas. Only sorry-free, correctly-stated proofs block this.
MISFORMALIZATION
Right proof, wrong question
Lean verifies the statement it is given. #728, #125, and #741 needed human disambiguation before a proof meant anything.
The fourth is the expert-verification bottleneck: 137 flawed papers were audited to extract 13 correct solutions.
The Compute Bill
First Proof second batch · per-problem compute
The same problems, an order of magnitude apart in cost.
CHATGPT 5.5 PRO
$117
Lowest overhead, fastest (Bubeck–Sawhney direct prompt) — but leans on a human loop to filter rapid algebraic hallucinations.
UCLA MOONSHOT
$4,800
Roughly 40× more expensive: correct but verbose, with heavy state-tracking and token-window depletion.
PROOFCOUNCIL
6 / 10
Strongest accuracy: IMProofBench’s multi-agent harness — still built on GPT-5.5 Pro, the one frontier model in play.
Gowers warns this cost gap could widen the global research divide.
Not Yet Shown
What has not been demonstrated — even now
ask
Choosing what is worth proving: First Proof explicitly does not score problem selection.
build
Constructing new frameworks, definitions, or fields — Clausen–Scholze-style rebuilding remains the domain of human insight.
frontier
Reliably judging the solvable frontier; commenters report models still have a “fuzzy” sense of what is in reach.
value
Judging significance in a way the community accepts; autonomous solves rarely rose above student-exercise level.
Open Disputes
What the community has not settled
solved
What counts as “solved”: a new proof, a variant, an obscure rediscovery, or database lag are now tracked apart.
credit
Authorship and publishing: arXiv bars AI-written content; some urge separate, human-moderated repositories.
training
Doctoral pathways: “gentle” PhD problems now fall in under two hours, raising the entry bar for newcomers.
access
Compute disparity: premium pipelines cost thousands per query, risking a widening global gap.

Tao · Trajectory
FROM CAUTIOUS USER TO EVANGELIST
Tao now calls 2025 “the year AI started being useful.”
Lean, AlphaEvolve, AlphaProof, autoformalization.
2025
the year AI “really started being useful” — Tao, Quanta
Tao · In His Own Words
“
“We have not had, in the past, assistants that are competent enough to understand complex instructions and work at massive scale — but are also unreliable, unreliable in subtle ways, whilst providing sufficiently good output.”
Terence Tao · Lex Fridman Podcast #472 · 2025
Tao · Strengths and Limits
Where Tao sees the real value — and the real bottleneck
tail
In the Erdős database, AI is good at systematically exploring the obscure long tail and finding “cheap wins” — but he warns this “says more about speed than difficulty.”
scale
The deeper opportunity is scale: tedious computations, many routine cases, proof-assistant translation, and population-study-style mathematics across thousands of problems at once.
gap
His “impedance mismatch”: generation is now orders of magnitude faster, while human verification and digestion are not — a move from proof scarcity to proof surplus.
limits
He rejects push-button autonomy for hard problems. AI is roughly a “junior co-author” for grunt work; humans still supply taste, inspired guesses, and sustained judgment.

from open problem to written-up result
Gowers · In His Own Words
“
“It is no longer enough that somebody asks a problem: it needs to be hard enough for an LLM not to be able to solve it.”
W. T. Gowers · A recent experience with ChatGPT 5.5 Pro · 2026
Gowers · Caveats
Impressed, with sharp caveats about where this works
field
Combinatorics may be unusually favorable: many explicit, askable problems may have easy arguments humans simply have not tried.
rule
His rule of thumb: “If it is difficult for a human to distinguish a correct statement from a plausible-sounding incorrect one, an LLM will not be able to distinguish them either.”
record
Results should enter the record only if a human certifies them — or, better, only if a proof assistant has formalized them.
bar
The new mark of a contribution may become proving something that LLMs cannot — and those who have solved hard problems themselves will use AI best.
Where We Stand

Part Five · Synthesis
Where
We Stand
What the evidence supports today, what it does not, and the sources behind every claim in this briefing.
Current Frontier
WHAT THE EVIDENCE SUPPORTS
AI is now useful for stated mathematical tasks.
The strongest public cases are construction search, literature retrieval, Lean proof search, proof-detail completion, and human-verified solutions to explicitly posed problems.
Tao would add AI is a complement, interface, and scale tool; humans still supply taste, inspired guesses, and sustained judgment.
Gowers would add Some askable problems are now too easy for LLMs; correctness and mathematical value still need human or formal certification.
So the conclusion is partial Not “AI can do mathematics.” Rather: AI can produce publishable-looking or verified work in favorable, well-specified settings.
