UnimeType Transliteration 2.0 0.8B โ€” v2.1 (Long-Sentence Upgrade ยท GGUF Q4_K_M & Q8_0)

Current Release: v2.1 (2.0-v4 Multi-Clause Long-Sentence Upgrade) ยท Protocol: unimetype-convert-short-v3 (100% drop-in compatible with all Transliteration-2.0 clients)

UnimeType Transliteration 2.0 0.8B (v2.1) is a specialized multilingual input-method transliteration model built on Qwen/Qwen3.5-0.8B. It converts Chinese Pinyin, Japanese Romaji, Romanized Hindi / Hinglish, and Arabic Arabizi into their native scripts across both short phrases and multi-clause long sentences (60โ€“240+ chars) while preserving English technical terms, @handles, URLs, code spans, JSON literals, numbers, line breaks, and emoji in place.


Quickstart: unimetype-convert-short-v3 JSON Protocol (LM Studio / llama.cpp / mlx_lm)

Important for LM Studio / Ollama / GGUF Users: This model is a deterministic IME transliteration engine, not a general chat bot. Pass a single-line compact JSON object as the user message (with empty System Prompt and temperature: 0.0), or use the UnimeType Keyboard App which formats requests and replaces text in-place automatically.

What's New in v2.1 (Long-Sentence Upgrade)

  1. Multi-Clause Long-Sentence Mastery (v2.0 โ†’ v2.1): Trained on a balanced curriculum where 67.2% of training inputs are multi-clause sentences (60โ€“240 chars, 2โ€“5 clauses, max_seq_len=1024) covering spaced, phrase-grouped, and unspaced romanization, bilingual technical code-switching, protected placeholders, multiline layouts, and Another (reconvert) cycling:
    • 0.8B (v2.0 โ†’ v2.1): Multi-clause strict pass up 13ร— (0.6% โ†’ 8.1%), long-sentence character accuracy 69.2% โ†’ 76.5% (ja +11.9%, ar +9.2%), and standard 414-case benchmark up from 66.4% (275/414) to 72.7% (301/414), surpassing DeepSeek V4.1 Flash (70.5%).
    • 4B (v2.0 โ†’ v2.1): Multi-clause strict pass up from 20.0% (32/160) to 28.8% (46/160, 29.4% normalized), long-sentence character accuracy 90.4% โ†’ 93.21% (all 4 languages >90.9%), contract violations cut by -76.9% (13 โ†’ 3), and standard 414-case benchmark up from 87.4% (362/414) to 88.4% (366/414) (ja 61.5% โ†’ 76.9%).
  2. Unconditional Non-Thinking Generation Template: Ships with an unconditional non-thinking chat_template.jinja (<|im_start|>assistant\n<think>\n\n</think>\n\n) across all formats (MLX 6-bit, BF16 Safetensors, and GGUF), preventing Thinking Process: token waste or truncation in LM Studio, mlx-lm, and llama.cpp.
