What it changes
If this result held, it would move the question forward without closing it. Erdős problem #12 belongs to number theory; on October 12, 2026, erdosproblems.com listed it as open.
What remains unclear
The wiki points to a proof in Lean (a language in which a computer checks every step of a proof) without naming a third-party verifier, and no independent verification is recorded. The sources read do not say what the first and second parts of the problem are, or what the result covers exactly.

this status is an unofficial crowdsourced classification of the problem
Method
Source: the “AI contributions to Erdős problems” wiki of the teorth/erdosproblems repository (a repository presented by Terence Tao in his blog post of August 31, 2025); frozen on June 30, 2026 (commit c8ad430, “freeze”) and read on October 12, 2026 in the git repository. Category 1(c), “AI building on literature” (literature known beforehand and not rediscovered afterwards; no significant human involvement). Humans named by the wiki: none; AI system: DeepMind prover agent. Date given by the wiki: April 7, 2026. Exact text: “Partial result (Lean) (solutions to first part and second part)”; yellow flag (“partial progress”, according to the wiki's legend). The wiki flags a Lean proof without naming a third-party checker. Prior literature cited by the wiki: Erdős and Sárközy (1970). Status of the problem in the teorth/erdosproblems community database (data/problems.yaml, unofficial classification, snapshot of October 12, 2026 with no commit identified, current state, not that of June 2026): open (informal_status=open); no formalised solution known (formal_status=unformalized). This status concerns the problem, not this contribution. Problem page not read by DiscoverIA: https://www.erdosproblems.com/12. DiscoverIA status: not evaluated (only the wiki's classification exists). Recorded on October 12, 2026.
Limits
DiscoverIA has not checked this contribution itself. The claimant supplies a Lean proof; as of this date, DiscoverIA has found no independent verification of this proof or of the result.
