Evidence Relationship: Supports
Vote on whether "Autoformalization success on undergraduate competition corpora rose from 8% to 61% between 2022 and 2025 on the miniF2F-Lean4 benchmark" is good evidence that supports the claim "By 2035 a machine-generated proof of a previously open Annals-level conjecture will be formally verified in Lean and accepted without a human-written proof sketch"
Evidence Claim
Autoformalization success on undergraduate competition corpora rose from 8% to 61% between 2022 and 2025 on the miniF2F-Lean4 benchmark
Tracking the public miniF2F-Lean4 leaderboard, the best reported pass@64 rate climbed from 8.2% (Dec 2022) to 61.4% (Nov 2025, reported by the Kestrel-7 group of Adeyemi & Lindqvist). Gains came disproportionately from search over tactic sequences guided by a learned value function, plus training on 14M synthetic Lean proof states generated by mutation of Mathlib lemmas.
Main Claim
By 2035 a machine-generated proof of a previously open Annals-level conjecture will be formally verified in Lean and accepted without a human-written proof sketch
The claim requires four conjuncts to hold jointly before 31 Dec 2035: (a) the target was an open problem of a difficulty class typically published in Annals of Mathematics or comparable venues; (b) the proof's mathematical content originates from an automated system, not from human-supplied intermediate lemmas or a strategy outline; (c) the artifact typechecks in Lean (or a successor with a comparable kernel); (d) the community treats the result as established. Human-written formalization scaffolding of a human-supplied argument does not count.

Worth noting the 61.4% figure is pass@64 with a 30-minute budget per problem. The pass@1 number is 34%, which is still remarkable but changes what 'solved' means for anyone reading quickly.
Fair — I should have put both in the description. pass@64 is the number the leaderboard ranks on, but you're right that it flatters the system if you imagine an unattended agent.
miniF2F saturating tells us about miniF2F. The relevant question is whether anything on that curve has ever produced a lemma a working mathematician didn't already know how to prove.
