# BabyLM Challenge 2026 submission | RecGPT-100M

RecGPT-100M is a 124.03M-parameter recursive causal language model trained for the BabyLM 2026 Strict track. It was trained for 10 epochs on a custom 100M-word English corpus using a 32,768-token BPE vocabulary.

The model applies a shared Transformer block recursively for 24 iterations. Its hidden size is 1,408, embedding size is 768, and feed-forward intermediate size is 22,528. Training used Aurora for the recursive block and AdamW for the embedding-related parameters, with a token batch size of 32,768 and sequence length 512.

## Usage

This repository contains custom Transformers code, so loading requires `trust_remote_code=True`:

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "Serdar404/RecGPT-100M-Fixed"
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(model_id, trust_remote_code=True)
```

The model is intended for scoring text as a causal language model. KV-cache generation is not currently implemented.

## BabyLM 2026 evaluation
