 # Til-vocab-morphbpe-96k-kkrumix-v1
 
-96K byte-level BPE multilingual tokenizer (kk / ru / en / code / math), **kk-priority**.
-Part of the **Til-MVP-1.1B** program (exp056). License MIT. 2026-06-07.
+Byte-level BPE tokenizer (96 000 vocab) for the **Til** Kazakh foundation-model program. Kazakh-priority, with Russian, English, code and math coverage.
+
+## Summary
+
+- **Vocab size:** 96 000 (byte-level BPE, `tokenizers`).
+- **Priority:** Kazakh-first; balanced kk/ru shares + en/code/math.
+- **Special tokens:** `<pad>`=0, `<bos>`=1, `<eos>`=2.
+- **Built on:** kaznu, from on-disk collected kk/ru (Til corpus exp053/054) + streamed en/code/math (FineWeb-Edu / code / math) — streaming avoids contention with the collectors.
+
+## Fertility (tokens/word, lower = better)
+
+| Lang | Fertility | Note |
+|------|-----------|------|
+| kk | 1.699 | ✅ target < 2.0 |
+| ru | 1.619 | marginal (aspirational < 1.6; +0.019) |
+| en | 1.355 | ✅ |
+
+Raising the Russian vocab share dropped ru fertility 1.718 → 1.619 (kk:ru mix tuning).
+
+## Usage
+
+```python
+from tokenizers import Tokenizer
+tok = Tokenizer.from_file("tokenizer.json")
+ids = tok.encode("Сәлеметсіз бе, әлем!").ids
+```
 
-## Fertility (tokens/word, held-out)
-| lang | value | gate | |
-|------|------:|-----:|--|
-| kk | 1.699 | <2.0 | OK |
-| ru | 1.619 | <1.6 | aspirational gate; marginally over (kk-priority shared vocab) |
-| en | 1.355 | <1.4 | OK |
+## Part of the Til program
 
-## Training sample (~5.3 GB)
-kk 1500 MB + ru 1100 MB from the collected exp053/exp054 corpora (on-disk),
-en 700 MB + code 700 MB + math 350 MB streamed (FineWeb-Edu / GitHub-Code / OpenWebMath).
-Special ids: pad 0 / bos 1 / eos 2 / unk 3 (must match the exp058 model config).
