📊 Full opportunity report: Every Benchmark Launched 2023-2024 Has Fallen — The METR / SWE-Bench / CORE-Bench / MLE-Bench / PostTrainBench Sequence on ThorstenMeyerAI.com — validation score, market gap, and execution plan.
TL;DR
Six key AI research benchmarks launched in 2023-2024 have all reached or are approaching saturation within months. This pattern suggests AI capability growth is accelerating faster than expected, impacting forecasts and policy considerations.
All six major benchmarks designed to measure AI research and development capabilities, launched between 2023 and 2024, have now saturated or are nearing saturation within months, according to recent analyses by Thorsten Meyer. This pattern indicates that AI progress in these areas is occurring much faster than many forecasts predicted, raising questions about the pace of AI development and its implications.
Thorsten Meyer’s recent review of six key benchmarks—SWE-Bench, METR Time Horizons, CORE-Bench, MLE-Bench, PostTrainBench, and CPU Speedup—shows that each has either been declared saturated or is tracking toward saturation on a short timeline of months. For example, SWE-Bench, which measures real-world software engineering performance, improved from 2% in late 2023 to 93.9% in May 2026, achieving saturation in 30 months with a 47× improvement. Similarly, METR Time Horizons, assessing task durations AI can reliably complete, expanded from 30 seconds in 2022 to 12 hours in 2026, a 1,440× growth over four years.
Other benchmarks, such as CORE-Bench, which evaluates research reproduction tasks, was declared solved by its authors in late 2025 after improving from 21.5% to 95.5% within 15 months. MLE-Bench, measuring end-to-end machine learning engineering, has shown continuous progress, with performance increasing from 16.9% to 64.4% over 16 months. The pattern across all six benchmarks indicates a rapid saturation trend, suggesting that the AI research capability landscape is evolving faster than previously understood.
Implications of Rapid Benchmark Saturation for AI Development
The saturation of all six key benchmarks within such a short period signals that AI systems are reaching levels of capability once thought to be years away. This rapid advancement could accelerate deployment timelines across industries, influence policy discussions on AI regulation, and impact workforce planning. It also challenges existing forecasts about AI progress, suggesting that capabilities may be approaching or surpassing human-level performance in various domains sooner than expected.
Furthermore, the pattern indicates that AI research is entering a phase of exponential growth, which may lead to unforeseen technological and societal shifts. Stakeholders in industry, government, and academia need to reassess their strategies in light of these developments, considering both the opportunities and risks associated with such rapid progress.

Historical Progress and Benchmark Development Timeline
Prior to 2023, AI benchmarks generally showed steady, incremental improvements over several years. The launch of these six benchmarks in 2023-2024 marked a strategic effort to measure the most challenging aspects of AI research, including software engineering, task duration, research reproduction, and hardware acceleration. The rapid saturation observed in these benchmarks is unprecedented, with improvements occurring on a scale of months rather than years, reflecting a significant acceleration in AI research capabilities.
These benchmarks were designed to be difficult and representative of real-world AI research tasks. Their quick saturation suggests that current AI systems are rapidly overcoming previously challenging barriers, indicating a potential paradigm shift in AI development trajectories.

Uncertainties About Long-Term AI Capability Trajectories
While the saturation of these benchmarks indicates rapid progress, it remains unclear how these results translate to broader AI capabilities outside controlled benchmarks. It is also uncertain whether this pattern will continue or if new benchmarks will emerge that challenge current saturation trends. Additionally, the impact of these advancements on real-world deployment, safety, and regulation is still being evaluated, and the long-term implications are not yet fully understood.
