From the Hugging Face model README
rostlabs/rost-286m-sft
286M parameter nanochat GPT (sft stage), research tag normalized-d12-004b, checkpoint step 000600.
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, 12 layers, 768 embed, 2048 context |
| tokenizer | included under tokenizer/ (32,768 vocab) |
| training mixture | Romanian SFT mixture (OpenLLM-Ro datasets) with input diacritic augmentation |
| stage | sft |
| val bpb (own split) | 0.49526 |
The best Romanian conversational model of the rost small series (research tag normalized-d12-004b). Input-side diacritic augmentation makes it robust to unaccented Romanian as actually typed (cum te cheama?). Base: rost-286m-base.
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.
