Re-evaluating the Pace of AI Efficiency: Is Catch-Up Progress Hitting 60x Annually?
Coverage of lessw-blog
In a compelling new analysis published on LessWrong, the author challenges existing estimates of algorithmic progress, proposing that the efficiency required to replicate frontier capabilities is improving at a rate of 16x to 60x per year.
In a recent post, lessw-blog discusses a potential anomaly in how the industry tracks Artificial Intelligence progress. While much of the conversation focuses on the sheer scale of compute clusters and the rising costs of training frontier models, this analysis looks at the inverse: how quickly the cost to reach a specific level of performance is dropping.
The Context
Historically, researchers have relied on benchmarks like those established by Ho et al. (2024), which analyzed the period from 2012 to 2023. That data suggested that pre-training compute efficiency-the ability to achieve the same result with less computational power-improved by approximately 3x annually. This rate is already impressive, outpacing Moore's Law significantly. However, as the AI ecosystem shifts from pure pre-training to complex post-training pipelines and architectural optimizations, the historical baseline may no longer apply to the current generation of models.
The Gist
The author of the LessWrong post argues that for the period of 2023-2025, "catch-up" algorithmic progress is moving significantly faster than the historical 3x trend. By analyzing data from Epoch AI and the Artificial Analysis Intelligence Index, the post tracks the compute efficiency of frontier models over time.
The findings are stark. When calculating the weighted mean of capability level slopes, the analysis indicates a 60x annual improvement in compute efficiency. This translates to a halving time of just two months. Even using a more conservative median metric, the improvement rate sits at 16x annually (a halving time of roughly 2.9 months). This suggests that the computational barrier to entry for "GPT-4 class" performance is collapsing far more rapidly than previously anticipated.
Why It Matters
If this analysis holds true, the implications for the AI market are profound. A 60x annual efficiency gain implies that open-weights models and smaller laboratories can replicate the capabilities of leading proprietary models with a lag time of only months, rather than years. It suggests that the "moat" provided by massive compute resources is more permeable than it appears, as algorithmic innovations (including better data curation and post-training techniques) allow for dramatic reductions in the resources needed to achieve state-of-the-art intelligence.
We recommend reading the full analysis to understand the methodology behind these numbers and what they signal for the democratization of high-level AI capabilities.

Key Takeaways
- Historical estimates (2012-2023) placed algorithmic progress at ~3x efficiency gains per year.
- New analysis suggests 'catch-up' progress for 2023-2025 is occurring at 16x to 60x annually.
- At a 60x rate, the compute required to match a specific capability level halves every 2 months.
- The study utilizes data from Epoch AI and the Artificial Analysis Intelligence Index to map capability slopes.
- These findings imply a rapid commoditization of frontier-level intelligence, lowering barriers for new entrants.
