From the Hugging Face model README
stefaniancu/rost-126m-diacritics-raw
126M parameter nanochat GPT (base stage), research tag raw, checkpoint step 001920.
Part of the rost model zoo — the full set of trained variants behind the rost research series, published for reproducibility. This is a research model, not a product.
| architecture | nanochat GPT, 8 layers, 512 embed, 2048 context |
| tokenizer | included under tokenizer/ (32,768 vocab) |
| training mixture | Romanian, no normalization (mixed cedilla/comma encodings left as crawled) |
| stage | base |
| val bpb (own split) | 0.96765 |
Diacritics-study ablation (research tag raw). Trained on unnormalized text; the only arm that emits legacy cedilla codepoints — the orthographic-consistency finding.
Validation bits-per-byte is measured on this arm's own validation split and is not comparable across arms — cross-arm comparisons in the rost write-ups are always cross-evaluated on identical text.
