A Rosetta Stone for AI Benchmarks (2512.00193v1)
Abstract: Most AI benchmarks saturate within years or even months after they are introduced, making it hard to study long-run trends in AI capabilities. To address this challenge, we build a statistical framework that stitches benchmarks together, putting model capabilities and benchmark difficulties on a single numerical scale. This acts as a "Rosetta Stone", allowing us to compare models across a wide range of abilities and time, even if they are not evaluated on the same benchmarks. Moreover, this works without assuming how capabilities evolve across time or with training compute. We demonstrate three applications of this framework. First, we use it to measure the speed of AI progress over time, and to forecast future AI capabilities. Second, we estimate the rate of improvements in algorithmic efficiency, finding estimates that are higher, but broadly consistent with prior work. Finally, we find that our approach can be used to detect rapid accelerations in AI progress.

Unifying AI Benchmark Evaluation: An Expert Perspective on "A Rosetta Stone for AI Benchmarks" (2512.00193)
Introduction
"A Rosetta Stone for AI Benchmarks" proposes a principled statistical framework to unify the evaluation of disparate AI models across heterogeneous benchmarks. This approach addresses the perennial issue whereby individual benchmarks rapidly saturate, leading to fragmented and temporally inconsistent measurements of AI capability. The authors formalize model capabilities and benchmark difficulties on a shared quantitative scale and demonstrate the utility of this framework for analyzing efficiency trends, forecasting capabilities, and detecting performance accelerations.
Methodological Framework
At the core, the methodology adapts ideas from Item Response Theory (IRT), operationalizing both model capability () and benchmark difficulty () onto a single axis. The observed benchmark score for model on benchmark is modeled as:
Here, the sigmoid captures the nonlinear relationship between model ability and performance: as increases, performance transitions smoothly from failure to success. Benchmarks are "stitched" together by solving for the parameters globally over a large dataset of 179 models and 38 benchmarks (filtered for sufficient overlap), enabling direct comparisons even between models not co-evaluated.
This model selection favors simplicity and identifiability. Anchor fixes (setting slope and difficulty for one benchmark) resolve scale and shift invariances, while regularization stabilizes the regression fit.
Model Capability and Benchmark Difficulty Calibration
The inferred model capabilities and benchmark difficulties are shown to align broadly with practitioner intuition. State-of-the-art models (e.g., GPT-5) consistently outrank previous generations, and top benchmarks (FrontierMath Tier 4) are rated as difficult. However, the framework sometimes overestimates difficulty for benchmarks lacking successful model completions, primarily due to data sparsity on the upper tail (flat sigmoid region).
Empirical calibration indicates strong numerical reliability: capability differences correspond closely to familiar jumps (e.g., GPT-4 vs GPT-5), and mapping capability to the "time horizon" metric—how long humans require for equivalent tasks—yields an correlation.

Multidimensionality and Specialization
The model assumes capability is uni-dimensional; analysis of residuals reveals this is a pragmatic but imperfect abstraction. Certain models, notably Anthropic's Claude and Google DeepMind's Gemini, show specialization on different benchmarks (coding vs multimodal tasks). This suggests labs optimize architectures for distinct objectives, reflecting multidimensional skill axes not captured by the scalar .

Algorithmic Progress and Scaling Laws
By pairing estimated capability scores with training compute (), the framework recovers historical scaling trends. Across LLaMA family models, capability scales linearly with , and effective algorithms reduce required compute by an estimated 4–20 annually (subject to high uncertainty), which is consistent with—but higher than—prior estimates. This provides quantitative support for measuring algorithmic efficiency advances separately from brute-force scaling.

Forecasting and Temporal Trends
Longitudinal extrapolation of the frontier yields a capability increase rate of ≈0.55 units/year, equivalent to repeated GPT-4.5 to GPT-5 leaps. Naively projected, this posits tripling current capabilities in three years, with top labs (OpenAI, DeepMind, xAI) within months of each other's frontier. Importantly, benchmarking saturation does not limit analysis range due to the framework's cross-benchmark synthesis.

Acceleration Detection
Synthetic and real data analyses validate that the framework can detect capability accelerations (e.g., rapid increases in slope). When simulated, a 2 acceleration is reliably detected within three months post-breakpoint under moderate noise. Applied retrospectively, a 1.95 acceleration coincides with the reasoning model paradigm shift in early 2024, corroborating external "time horizon" acceleration metrics.
Figure 7: Synthetic detection identifies a 2 acceleration post-breakpoint.
Figure 8: Real model data exhibits a 1.95 acceleration, temporally aligned with paradigm shift events.
Robustness and Limitations
Several robustness checks are performed, including varying benchmark inclusion, anchors, overlap criteria, and statistical modeling choices (sigmoid vs clipped linear). All confirm the principal findings: capability rates are stable across variations, and there is no statistically significant evidence of systematic benchmark gaming or overfitting by labs.
Yet, interpretability challenges remain. Capability metrics are not directly translatable to real-world task automation due to benchmark limitations (task realism, economic value, evaluation setting idiosyncrasies). The single-number capability assumption, while operationally convenient, omits skill vector composition—future work should explore multidimensional extensions (e.g., PCA-based decompositions).
Figure 9: Varying benchmark anchors yields negligible shifts in capability/difficulty estimates—robust anchoring.
Broader Implications and Future Developments
By consolidating disparate benchmarking efforts, this framework enables unified analysis of AI progress, algorithmic improvement rates, and systemic risk (e.g., detection of abrupt capability shifts). Practically, its application in the Epoch Capabilities Index provides continuously updated insights critical for research prioritization, policy consideration, and safe deployment. The system's extensibility allows practitioners to weight, filter, or modify included benchmarks to suit specialized evaluation requirements.
Open avenues include:
- Modeling and monitoring multidimensional capability vectors
- Incorporating item-level (question-level) response data for finer granularity
- Enriching benchmarks to better reflect economically relevant tasks and operational settings
- Formalizing acceleration detection methods from advanced time-series/statistical sequential analysis
Conclusion
The "Rosetta Stone for AI Benchmarks" establishes an effective, extensible method for aggregating cross-benchmark model performance into unified capability and difficulty metrics. The resulting analyses afford comparative, longitudinal, and acceleration-sensitive perspectives that were unattainable via isolated benchmarks. As the field advances toward more general and economically substantive AI, frameworks like this will be foundational for rigorous capability tracking, forecasting, and model evaluation.

Overview: What this paper is about
This paper tackles a big problem in AI research: most tests (called “benchmarks”) get solved quickly, so it’s hard to track AI progress over many years or compare different models that weren’t tested on the same things. The authors build a simple “translator” for benchmarks — like a Rosetta Stone — that puts both model ability and test difficulty on the same scale. That lets us compare many AI models across time, even if they were measured on different tests.
Key questions the paper asks
- Can we create one shared scale that tells us how capable an AI model is and how hard each benchmark is?
- Can this scale help us track AI progress over time and make simple predictions?
- Can it help estimate how much of AI improvement comes from smarter methods (algorithms), not just more computing power?
- Can it spot sudden “jumps” or accelerations in AI progress?
How they did it (in plain language)
The authors gathered many scores from many AI models on many benchmarks (179 models, 38 benchmarks, 1,324 scores). Some of these came from their own tests, others from public results. Then they fit a simple statistical model that treats:
- each model as having a single “capability score” (how strong it is overall), and
- each benchmark as having a “difficulty score” (how hard it is), plus a “slope” (how sharply scores jump as models get better).
Think of it like this:
- Models are students with a single overall skill level.
- Benchmarks are tests with a difficulty level (how tough) and a sharpness (how quickly scores climb from failing to acing as students get better).
They assume scores follow an S-shaped pattern:
- If a test is too easy, strong models all get near 100%.
- If a test is too hard, weaker models all get near 0%.
- In the middle, small changes in ability lead to big score changes.
By fitting this S-shaped pattern across many model–benchmark pairs, they can “stitch” everything together onto one shared ruler: higher numbers mean stronger models; higher benchmark numbers mean harder tests.
Technical choices, explained simply:
- They use a standard curve-fitting method (least squares with a small regularizer) to find the numbers that best match all the observed scores.
- Because the scale could be shifted or stretched in many equally good ways, they pin it down by choosing one benchmark (WinoGrande) as the anchor: they set its difficulty to 0 and its slope to 1. This makes the numbers comparable across runs.
Main findings and why they matter
Here are the most important takeaways from the stitched-together scale.
- Models and benchmarks both got tougher over time
- Newer models have higher capability scores.
- New benchmarks are increasingly difficult (which is good, because they keep challenging new models).
- The rankings make sense
- Stronger modern models (like GPT-5-level systems) rank above earlier ones, matching everyday experience.
- Harder tests (like FrontierMath Tier 4) rank as tougher than easier ones.
- A single number surprisingly predicts “how big” tasks are
- The model’s capability score strongly predicts a “time horizon” — roughly, how long tasks take humans to do at the same success rate. Higher capability → longer, harder tasks.
- Their stitched capability score predicts time horizons better than most individual benchmarks.
- Simple, real-world progress trend and forecast
- The strongest (frontier) models have improved by about 0.55 “capability units” per year — roughly the jump from GPT-4.5 to GPT-5 in a year.
- If that kept up, we’d expect around 1.6–1.8 more units in three years (a big jump), roughly matching a move toward tasks that take weeks for humans to complete.
- Labs may specialize
- Some models do a bit better than expected on coding (e.g., some Claude models on SWE-Bench Verified), while others do better on multimodal tasks (e.g., some Gemini models on GeoBench). That suggests different labs optimize for different strengths.
- Algorithmic progress (smarter methods) looks fast, but uncertain
- They relate capability to training compute and find that, for frontier models, the compute required to reach a fixed ability seems to drop by around 6× per year on average (with big uncertainty).
- Put another way: even if you didn’t increase compute, smarter training alone could raise capability notably each year.
- Because results depend on limited families of models and assumptions, these numbers come with wide error bars.
- Detecting “accelerations” in progress is possible
- In simulated tests, their method can typically spot a 2× acceleration within 2–3 months when noise is moderate.
- On real data, they see a notable acceleration around spring 2024 (about 1.95×), which lines up with the rise of “reasoning” models and other evidence from independent studies.
What this research could change
- Better long-term tracking: Because benchmarks saturate fast, this stitched scale gives a stable way to track progress over years, not just months.
- Clearer comparisons: It helps compare models tested on different benchmarks — a common real-world problem.
- Practical forecasting: Even a simple trendline on the stitched scale produces useful, interpretable forecasts and can warn us if progress speeds up suddenly.
- Smarter measurement: It shows which benchmarks are too easy or too hard, guiding where new tests are needed.
- Policy and planning: If capabilities are climbing steadily (and sometimes accelerating), companies, researchers, and policymakers can plan evaluations, safety checks, and deployments more responsibly.
Important notes and limits
- One number can’t capture all abilities
- Real AI skills are multi-dimensional (e.g., coding vs. vision). The single capability score works surprisingly well overall, but some models specialize.
- Benchmarks have flaws
- Some tests have errors, don’t reflect real-world tasks, or depend heavily on prompts and scaffolding. The stitched results inherit these issues.
- Early data can mislead
- Very new, very hard benchmarks often show many low scores, which can make them look even harder than they really are until more models improve.
- Acceleration alarms need confirmation
- The detection method is a helpful early-warning tool, but it can raise false alarms. It works best when combined with other evidence.
In short: The authors propose a simple, cheap, and surprisingly powerful way to “translate” many AI benchmarks onto one shared scale. That makes it much easier to understand how fast AI is improving, compare different models fairly, estimate the role of smarter algorithms, and notice when progress speeds up.
Knowledge Gaps
Unresolved gaps, limitations, and open questions
Below is a concise, actionable list of what remains missing, uncertain, or unexplored in the paper’s framework and results.
- Validate the single-dimensional capability assumption by building and comparing multidimensional latent ability models (e.g., domain-specific components for coding, math, multimodal), and test whether they significantly reduce residuals on specialized benchmarks.
- Quantify how much lab-specific optimization (e.g., Anthropic for code, Google DeepMind for multimodal) biases the single-score capability estimates; develop methods to correct for systematic specialization.
- Replace aggregate benchmark scores with item-level data where available and adapt the model toward question-level Item Response Theory to avoid arbitrary weighting artifacts (e.g., splitting one benchmark into two inflates its influence).
- Develop a principled benchmark weighting scheme (e.g., based on reliability, coverage, domain importance, error rates) and evaluate how weights affect capability and difficulty estimates.
- Measure and correct for evaluation setting heterogeneity (prompting, scaffolding, inference compute, temperature, tools) across “external” benchmarks; provide sensitivity analyses showing how these factors shift capability scores.
- Improve uncertainty quantification beyond the current sensitivity-based “error bars” and 5% loss threshold (e.g., via Bayesian hierarchical modeling, bootstrapping across models/benchmarks, and posterior intervals for C, D, α).
- Test alternative link functions and heteroscedastic error models beyond a single sigmoid per benchmark (e.g., mixture of sigmoids, probit, spline-based link) to capture non-sigmoidal score dynamics and plateaus.
- Assess whether benchmark slope parameters αb are stable over time and across evaluation protocols; investigate dynamic αb that adapt to evolving benchmark composition and scoring procedures.
- Systematically evaluate the impact of anchoring on WinoGrande (αWinoGrande=1 and DWinoGrande=0): perform anchor-swap experiments to test scale and shift invariance and to quantify anchor-induced bias in C and D.
- Report sensitivity of results to the L2 regularization strength (default = 0.1) and justify its choice; provide a hyperparameter sweep and demonstrate convergence stability under different initializations.
- Address potential overestimation of difficulties for new, unsaturated benchmarks (flat tail of sigmoid): propose calibration strategies (e.g., adaptive sampling to target mid-sigmoid regions, human/legacy model baselines).
- Expand benchmark coverage to reduce domain bias (e.g., economically relevant tasks, software engineering beyond SWE-Bench, multimodal grounded tasks, robotics/control, non-English and cross-lingual tasks).
- Introduce explicit treatment of benchmark ceilings/floors and error rates (label noise, ambiguous items) to avoid misinterpreting plateaued performance as capability limits.
- Validate out-of-sample predictive power by training on a subset of benchmarks and predicting performance on held-out benchmarks and models; report predictive metrics and failure modes.
- Incorporate speed, latency, cost, and energy as auxiliary axes of “capability” to better align the unified scale with practitioner-relevant trade-offs; explore multi-objective capability indices.
- Improve the mapping from capability to “time horizon” by expanding overlap with METR data, testing robustness across more models and domains, and validating temporal stability of the mapping as reasoning models change trends.
- Clarify and improve compute data quality: detail sources, uncertainty bounds, treatment of synthetic data generation, distillation, curriculum, and inference-time compute used during evaluation; propagate compute measurement error into algorithmic progress estimates.
- Move beyond estimating k from only three LLaMA families; add more families with documented training recipes to reduce variance and test whether k is algorithm- and scale-dependent.
- Test scale dependence of algorithmic progress explicitly (does k vary across 1021–1025 FLOPs?), rather than assuming a constant k across scales and time; quantify how this affects annual “×” estimates.
- Separate the effects of algorithmic progress and training compute more rigorously (e.g., instrumental variables, matched pairs, or controlled ablation studies) to address endogeneity and confounding.
- Reassess exclusion of distilled models: quantify how distillation and synthetic data alter the C–log(F) relation and provide corrected estimates or separate progress curves for distilled vs non-distilled lines.
- Formalize the definition of “frontier models” and test how different frontier-selection criteria affect trend slopes, breakpoints, and forecasting (e.g., top-k, Pareto front across capability/cost).
- Strengthen acceleration detection with change-point and sequential testing methods (e.g., CUSUM, Bayesian online change detection) to reduce false positives (~38% reported) and provide calibrated thresholds (targeting e.g., 5% FPR).
- Evaluate detection latency and specificity under real-world noise by integrating benchmark reliability scores, model-release cadence, and observation-window constraints; provide operational guidance for monitoring.
- Provide a plan for continuous, incremental updates (online fitting) with principled handling of identifiability, anchor stability, and time-varying benchmark properties as new models/benchmarks arrive.
- Explore cross-lab comparability audits: run standardized, replicated evaluations to reconcile internal vs external results and quantify lab-level systematic offsets or variance.
- Examine geographic, language, and modality coverage gaps and assess whether capability scores transfer across languages/cultures; add multilingual/multimodal anchors to improve generality.
- Test the forecasting method under structural breaks (e.g., paradigm shifts like reasoning models) using scenario-based and mechanistic models tied to drivers (compute trends, data availability, algorithmic innovations) rather than pure linear extrapolation.
- Publish detailed reproducibility kits: datasets, compute estimates, evaluation scripts, and benchmark metadata to enable independent replication and robust sensitivity checks across different research teams.

Notes on cross-cutting dependencies and assumptions
- Data quality and coverage: Reliable, overlapping benchmark evaluations are essential. External scores vary in scaffold/prompt; internal consistency improves fit quality.
- Modeling choices: The sigmoid form and single-dimensional capability are pragmatic simplifications; multidimensional extensions will better capture specialization.
- Mapping to real-world performance: Time-horizon mapping provides interpretability but is statistical; deployment constraints (latency, cost, reliability, tools) are not encoded.
- Forecast risk: Extrapolations do not model causal drivers (compute, algorithms, data); expect deviations if compute growth slows or agentic R&D accelerates.
- Detection specificity: Acceleration detection is useful for monitoring, not adjudication; pair with additional evidence before policy or deployment changes.
