This preprint proposes L-State, a framework that uses four standardized micro-interventions to predict how language models will respond to further training. Across development and sealed test sets, the method reduces prediction error substantially relative to capability alone, but the work remains unreviewed and is designed for machine learning model development rather than clinical or consumer application.
Computational methods development with leave-one-family-out validation and sealed test evaluation. Language model checkpoints from GLM-4-9B, Granite-3.1-8B, and three additional model families; no human or clinical participants.. Intervention: L-State framework: four standardized target-independent micro-interventions applied to model checkpoints, with direct and operator readouts to predict training response. Compared with: Current capability (benchmark score) alone as baseline predictor.
In three-family leave-one-family-out development, both pulse readouts reduce source-standardized MSE by 39.4% relative to capability alone On sealed GLM-4-9B, operator readout reduces MSE by 78.3% and raises sign balanced accuracy from 0.366 to 0.754 On sealed Granite-3.1-8B, direct readout reaches RMSE 0.544 compared with 1.172 for capability alone

This is an unreviewed computational methods paper presenting a novel framework for predicting language model training response; it demonstrates proof-of-concept on multiple models but lacks clinical or real-world validation and has not undergone peer review.

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
Benchmark scores describe what a checkpoint can do now, but they do not determine how it will respond to the next training episode. We measure this missing state by branching four short, standardized, target-independent micro-interventions from the same checkpoint and recording their effects in a common capability space. Together with current capability, these responses form L-State; its pulse block supports a flexible direct readout and a structure-preserving operator readout. Under smooth local dynamics, the operator construction admits an end-to-end cross-family bound with explicit source- and target-family coordinate heterogeneity. In three-family leave-one-family-out development, both pulse readouts reduce source-standardized MSE by 39.4% relative to capability alone, while separating the best response and direction estimates. On sealed GLM-4-9B, the direct and operator readouts reduce MSE by 71.8% and 78.3%, respectively, and the operator readout raises sign balanced accuracy from 0.366 to 0.754. On sealed Granite-3.1-8B, the direct readout reaches RMSE 0.544 and a development-fitted action-wise selector reaches 0.554, compared with 1.172 for capability alone. A five-family audit finds that the operator coordinate varies by action and family, and that modeling these deviations improves retrospective held-trajectory prediction. Target-independent interventions therefore expose training-response information that current capability misses, with direct and structured readouts covering complementary transfer regimes.
