# Tiny GPT memorization checkpoint (8m, near-capacity / saturation boundary)
From an exploratory tiny-scale replication of
[How much do language models memorize?](https://huggingface.co/papers/2505.24832).
- Architecture: GPT-2 (transformers), trained from scratch.
- Parameters: 7,916,160 (non-embedding 7,098,624).
- Vocab: 2048 data tokens (uniform random) + BOS = 2049 model vocab.
- Sequence length: 64 (paper S=64).
- Dataset: 44000 sequences, 2,816,000 data tokens,
dataset entropy 30,976,000 bits (30.976 Mbits).
- Trained 15698 steps, AdamW, bfloat16, lr 0.002, batch 512.
- Result: train loss 5.8075 bits/tok, held loss 16.6023,
memorized 14,622,163 bits = **1.847 bits/parameter**.
This is the **near-capacity (saturation-boundary)** run for this model size.
Below- and above-capacity checkpoints for the same architecture are published as
`state.pt` files in the results dataset `evalstate/tiny-memorization-results`.
Load with:
```python
from transformers import GPT2LMHeadModel
model = GPT2LMHeadModel.from_pretrained("evalstate/tiny-gpt-memorization-8m")
```
Findings are scoped as an exploratory tiny-scale check (three architectures),
NOT a universal scaling law.
