AI solves ten FrontierMath open problems by 2028

Using the reference class of hard-benchmark saturation followed by transfer to genuinely novel, reviewer-verified mathematics, I expect slower, clustered progress than score gains: original solutions are not independent benchmark trials. With no current reading beyond the 2-problem baseline, reaching 10 requires eight verified additions in about 26 months, roughly 3.7 annually. A low/medium/high progress-regime mixture gives about 0.44 for that pace. I reduce this to 0.41 for Epoch-page continuity and the strict January 2 cutoff, which excludes partial, human-assisted, or still-under-review work. This is below 0.65 because Tier 4 saturation is weak evidence for near-term research-solution throughput.

Starting from 2, the rule requires 8 additional verified, non-human-assisted solutions in roughly 26 months. My reference class is the lag from benchmark saturation to independently verified research outputs: capability jumps can accelerate attempts, but acceptance and author review create long, uneven tails, while remaining problems may be unusually resistant. An accelerating count model with roughly 2–3 additions in 2027 and 3–5 in 2028 leaves the threshold in the upper tail. I also deduct slightly for Epoch discontinuing the tracker, which automatically resolves MISS. The connector provides no evidence beyond the September baseline. The stated 0.65 overweights transfer from Tier 4 benchmark performance.

I use the reference class of benchmark saturation translating into verified, autonomous research results: progress usually slows when moving from curated problems to novel proofs, and verification/publication adds lag. Starting from 2, the thesis requires 8 additional credited solutions in roughly 27 months. My central path is 2–3 additions in 2027 and 3–4 in 2028, leaving the median below 10, though capability jumps create substantial upside. The rule also excludes partial and human-assisted work and requires Epoch’s page to remain active. With no current indicator update, I discount the forecaster’s 0.65 as relying too heavily on Tier 4 benchmark transfer.

I use the sparse 2026 incidence—2 of roughly 50—as the base rate, rather than closed-benchmark saturation. Reaching 10 requires eight additional verified, autonomous solutions in about 26 months. That needs a marked increase in the annual solve hazard across a heterogeneous set; capability gains could produce correlated batches, but research-level correctness, attribution and review create substantial lags. The literal rule also excludes partial or human-assisted work and adds some page-continuity risk. These constraints make the outcome plausible but less likely than the stated 0.65.

The reference class is first-time AI solutions to curated research problems, not benchmark-score gains. Starting from 2, the thesis needs 8 additional verified, qualifying solutions in roughly 27 months—about 3.5 annually. A simple count model with a 3–4 solve annual rate gives substantial but not dominant threshold probability; capability acceleration raises the upper tail, while correlated problem difficulty reduces it. FrontierMath Tier 4 saturation is encouraging but transfers imperfectly to novel research, and Epoch’s verification, no-human-assistance, and cutoff-date requirements create publication and classification risk. I also discount modestly for the explicit page-continuity condition. These factors put the claim below the forecaster’s 0.65.

I use 0.30 as the outside-view base rate for a newly breached, deliberately resistant research benchmark increasing its verified autonomous solve count at least fivefold within 2–3 years. From the stated baseline of 2, this requires 8 additional credited solves in about 28 months, averaging 3.5 per year. The first 2026 solves and rapid Tier 4 gains justify an upward adjustment. However, benchmark saturation is weak evidence for author-verified novel mathematics; partial, human-assisted, and under-review work is excluded. Exact Epoch publication by the deadline and page-continuity requirements add risk. The stated 0.65 overweights one benchmark analogy.
