About

What chinese-babylm-cog-a197-strict-best is

Model Summary

chinese-babylm-cog-a197-strict-best is a custom BERT-based wrapper model for the NLPCC 2026 Chinese BabyLM shared task, optimized for the Cognitive Modeling (Cog) Track. It combines internal strict BERT branches, official-corpus static features, and MLM uncertainty features for brain-aligned fMRI evaluation.

Components

Word branch: A180 strict word BERT, layers [2,3,4] concat, RI scale 3.05 + log-frequency features.

Sentence branch: A130 + gamma -5.1 × (A158_s0250 − A122_s1500), layers [6,7,8] weighted [0, 0.98, 0.02] + raw384 window8 + log-frequency features.

Uncertainty: A129 step_01000 MLM features (logprob, surprisal, entropy, margin, probability), scale 1.25.

Hidden Evaluation

Usage

from transformers import AutoModel, AutoTokenizer

repo_id = "LikC1606/chinese-babylm-cog-a197-strict-best"
tokenizer = AutoTokenizer.from_pretrained(repo_id, trust_remote_code=True)
model = AutoModel.from_pretrained(repo_id, trust_remote_code=True, output_hidden_states=True)

inputs = tokenizer("春天的花开了。", return_tensors="pt")
outputs = model(**inputs, output_hidden_states=True)

Limitations

  • Feature extraction model only, not for text generation.
  • Requires trust_remote_code=True.
  • Optimized for Cog track; not intended as a general NLU model.

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys chinese-babylm-cog-a197-strict-best for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (chinese-babylm-cog-a197-strict-best below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/embeddings \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"chinese-babylm-cog-a197-strict-best","input":"text to embed"}'
