Base + Language-Specific LangMAP — gemma2-2b × fin_Latn

Unsupervised tokenization specialised for fin_Latn, derived from the gemma2-2b base BPE tokenizer using the LangMAP framework.

This repository bundles:

• base_tokenizer.json — joint LAS Unigram base
• langspec_fin_Latn.json — language-specific overlay (re-EM on fin_Latn corpus)
• tokenizer.json — alias for the overlay (default load target)

Inference uses base + language-specific scores together (the LangMAP variant); do not use the bare overlay or base on its own.

Trained from job smoke.fin.gemma2-2b.v256000 (vocab=256000, langs=[fin_Latn], iters=5, em_mode=soft, byte_fallback=True, seed-fix applied).
