## Summary

Qiushi Engine's BabyLM 2026 Strict-Small project, using only a 10 million corpus and 100 million word presentations, conducted a comprehensive research program. The study divided into three stages: first, it combined compact restatements with budget reinvestment and residual incremental learning to create an advanced model; second, it discovered that exact repetition and aligned restatement have different patterns of context use based on target relations and prediction windows; third, it retained source text while masking more local clues, supervised selected targets, and preserved predictions on normally masked inputs. This led to improved performance across multiple metrics. The research also explored compression, relational anchors, shared representations, and measurement methods. These findings support a data-efficient learning principle: organize experience around needed contextual dependencies, design visible information and supervision separately, and test learning, generalization, and retention. All models are available on Hugging Face; the GitHub repository contains code and research records.

## Key points

- BabyLM 2026 Strict-Small used only a 10 million corpus and 100 million word presentations
- Three stages of research found different patterns of context use for exact repetition vs. aligned restatement
- Improved model performance across multiple metrics

## Why it matters

These findings provide insights into data-efficient learning, which could significantly reduce the need for large datasets in AI training.
