📊 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 benchmarks launched between 2023 and 2024 have all reached saturation or are close to it within months. This pattern suggests AI research is advancing faster than expected, with implications for AI development and deployment timelines.
All six major AI research benchmarks launched in 2023 and 2024 have been saturated or are nearing saturation within months, according to recent analysis by Thorsten Meyer. This pattern indicates that AI capabilities are advancing at a faster rate than previously estimated, with significant implications for AI development timelines and deployment strategies.
Thorsten Meyer’s latest review highlights that each of the six benchmarks designed to measure AI research and engineering skills has either been declared solved, saturated, or is rapidly approaching that point. These benchmarks include SWE-Bench, METR Time Horizons, CORE-Bench, MLE-Bench, PostTrainBench, and CPU Speedup, each assessing different facets of AI progress.
For example, SWE-Bench, which measures real-world software engineering capabilities, improved from 2% in late 2023 to 93.9% in May 2026, achieving saturation after 30 months. Similarly, METR Time Horizons, measuring task durations AI can reliably complete, expanded from 30 seconds in 2022 to 12 hours in 2026, representing a 1,440-fold improvement over four years. The CORE-Bench, which reproduces research papers, was declared solved in December 2025 after reaching 95.5% from 21.5% in September 2024, marking a 15-month progression.
These rapid advancements suggest that AI research is approaching a phase where many capabilities are effectively saturated, challenging previous assumptions about the slow pace of AI development and raising questions about the future trajectory of AI progress.
Implications of Rapid Benchmark Saturation for AI Progress
The saturation of these benchmarks within such short timeframes indicates that AI systems are rapidly approaching human-level or superhuman performance across a range of critical skills. This accelerates the timeline for deploying advanced AI in real-world applications, potentially transforming industries, workforce dynamics, and AI regulation. It also raises concerns about the limits of current evaluation methods and the need for new benchmarks to measure future AI capabilities accurately.

Recent Trends in AI Benchmark Performance Improvements
Over the past few years, AI research has seen exponential improvements across multiple benchmarks, driven by advancements in model architectures, training compute, and data availability. Notably, the METR Time Horizons benchmark has expanded from 30 seconds to 12 hours, while SWE-Bench has seen a 47× improvement, reflecting a pattern of rapid progress since 2022.
These benchmarks were explicitly designed to challenge AI systems and measure different aspects of AI research and engineering. The fact that all six launched in 2023-2024 are now saturated suggests a structural shift in AI development, where many capabilities are reaching their upper limits within months rather than years.
“The pattern across all six benchmarks indicates that AI capabilities are advancing faster than previously thought, with saturation occurring within months rather than years.”

Uncertainties Surrounding Benchmark Saturation and Future Progress
While the saturation of these benchmarks is well-documented, it is unclear whether they fully capture the limits of AI capabilities or if future benchmarks will reveal new challenges. There is also uncertainty about whether current evaluation methods remain valid as models approach saturation, and how this rapid progress will influence regulatory and ethical considerations.
Additionally, the extent to which saturation indicates true generalization or merely overfitting to specific benchmarks remains under discussion among experts.

Next Steps in Monitoring AI Capability Growth
Researchers and industry observers will likely focus on developing new, more challenging benchmarks to measure ongoing AI progress beyond current saturation points. Monitoring how models perform on these next-generation tests will be critical to understanding if the rapid advancements continue or plateau.
Further analysis is expected to assess whether saturation indicates genuine mastery of skills or if models are exploiting overfitting and data contamination. Regulatory bodies may also review the implications of these rapid capabilities for AI safety and governance.

Key Questions
What do benchmark saturations mean for AI development?
Saturation suggests that AI systems are reaching or have reached human-level performance in specific skills, indicating rapid progress and possibly signaling a new phase in AI development.
Are current benchmarks sufficient to measure future AI capabilities?
Likely not. As benchmarks saturate, new, more challenging tests will be needed to gauge ongoing progress and prevent overfitting or overestimation of AI skills.
How might this rapid saturation impact AI deployment?
It could accelerate the deployment of advanced AI systems across industries, but also heighten risks related to safety, ethics, and regulation due to faster-than-expected capability growth.
Is this saturation indicative of true AI mastery?
Not necessarily. Saturation may reflect overfitting or models exploiting data patterns rather than genuine understanding, which underscores the need for more robust evaluation methods.
