Epoch AI's Tier 4 Math Benchmark Saturated: 5% to 98% in 14 Months
Jsevillamol · x · 2026-09-11
- Citing official Epoch AI data: when the Tier 4 math benchmark launched on July 11, 2025, the top score was just 5%; less than 14 months later the top score is 98% and the benchmark is considered saturated.
- The retweeter notes AI's math progress felt sudden: LLM-based models couldn't even add three years ago, now they top hard math evals.
- Another sign that benchmark saturation is outpacing eval design.
