Stage III model in Qiushi Engine's BabyLM Strict-Small research program.
Frontier Advancement -> Principle Discovery -> Principle-Guided Frontier Advancement.
This model continues training from the Stage I model. It hides more words in each rewrite while retaining the source passage, and applies prediction loss only at selected positions. An additional loss keeps predictions on ordinarily masked inputs close to those of the parent model. Only the second adapter is updated.
The two releases connect three research stages: training a limited-data language model, studying how it learns from paired texts and retains learned behavior, and using those findings to develop a continuation method tested against matched controls.
Companion model: Qiushi-Engine-Frontier-Advancement.

| Parameters, including masked-language-model head | 36,458,592 |
| Encoder parameters | 36,210,368 |
| Second adapter parameters | 995,584 |
| Layers / hidden size / attention heads | 8 / 480 / 8 |
| Adapter bottleneck / scales | 128 / 1.75 and 0.75 |
| Tokenizer | 16,384-entry byte-level BPE |
| Corpus budget | 10,000,000 counted words in 64,740 rows |

| Local full-evaluation Overall | 42.2464 |
Use
from transformers import AutoModelForMaskedLM, AutoModel, AutoTokenizer
repo = "leslie721007/Qiushi-Engine-Principle-Guided-Frontier-Advancement"
tokenizer = AutoTokenizer.from_pretrained(repo)
model = AutoModelForMaskedLM.from_pretrained(repo, trust_remote_code=True)
encoder = AutoModel.from_pretrained(repo, trust_remote_code=True)
The custom code is required: both adapter paths are part of the model. The encoder
entry point supports downstream fine-tuning. The included requirements.txt records
the tested model-loading environment. For a fixed experiment, use the same Hub commit
for tokenizer, model and encoder.
Full Evaluation
Local results from the full BabyLM evaluation. SuperGLUE uses the custom encoder with both adapters and fine-tuning seed 42.
| Component | Score |
|---|---|
| BLiMP | 68.2600 |
| Supplement | 63.2800 |
| EWoK | 49.8200 |

Overall is the arithmetic mean of the nine components. Age of Acquisition (AoA) was evaluated across 18 checkpoints and scored 0.
Research Comparison
| Method | Continuation seed 62064 | Continuation seed 62065 |
|---|---|---|
| Stage I parent | 42.0240 | 42.0240 |
| Ordinary continuation | 42.0926 | 42.1159 |
| Dense input masking, sparse target supervision | 42.2025 | 42.1789 |
| With ordinary-input preservation | 42.2464 | 42.2317 |
Both continuation runs start from the same Stage I model. The final method improves Overall over ordinary continuation in each run; individual task scores vary. METHOD.md explains the training changes and what the comparisons measure.
Artifacts
EVALUATION.json: exact local component scores and model identity.METHOD.md,TRAINING.md,DATA.md: design, recorded training and data provenance.CHECKPOINTS.json: shared intermediate checkpoints and actual exposure counts.evaluation/: complete final prediction files, AoA measurements and Fast metrics.submission/: full and full-plus-Fast official-format prediction bundles.VALIDATION.json: package loading and save/reload tests.
Intended uses are masked-token prediction, sentence scoring and encoder fine-tuning. The experiments cover English language modeling under the BabyLM Strict-Small budget.
