rostlabs/rost-126m-diacritics-stripped
126M parameter nanochat GPT (base stage), research tag stripped, 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.

Diacritics-study ablation (research tag stripped, d8). Pays ~57% more bits-per-byte than the normalized twin on correct Romanian.
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.
