+# **beomi/Yi-Ko-34B**
+
+Yi-Ko series models serve as advanced iterations of 01-ai/Yi models, 
+benefiting from an expanded vocabulary and the inclusion of Korean/English corpus in its further pretraining. 
+Just like its predecessor, Yi-Ko series models operate within the broad range of generative text models that stretch from 6 billion to 34 billion parameters.
+This repository focuses on the **6B** pretrained version,
+which is tailored to fit the Hugging Face Transformers format. 
+For access to the other models, feel free to consult the index provided below.
+
+## Model Details
+
+**Model Developers** Junbum Lee (Beomi)
+
+**Variations** Yi-Ko series will come in a range of parameter sizes — 6B and 34B variations.
+
+**Input** Models input text only.
+
+**Output** Models generate text only.
+
+**Model Architecture** 
+
+Yi-Ko series models are an auto-regressive language model that uses an optimized transformer architecture based on Llama-2*.
+
+<small>*Yi model architecture is based on Llama2, so it can be loaded via `LlamaForCausalLM` class on HF.</small>

+**Vocab Expansion**
+
+| Model Name | Vocabulary Size | Description | 
+| --- | --- | --- |
+| Original Yi-Series | 64000 | Sentencepiece BPE |
+| **Expanded Yi-Ko Series** | 78464 | Sentencepiece BPE. Added Korean vocab and merges |
+
+**Tokenizing "안녕하세요, 오늘은 날씨가 좋네요.ㅎㅎ"**
+
+| Model | # of tokens | Tokens |
+| --- | --- | --- |
+| Original Yi-Series | 47 | `['<0xEC>', '<0x95>', '<0x88>', '<0xEB>', '<0x85>', '<0x95>', '하', '<0xEC>', '<0x84>', '<0xB8>', '<0xEC>', '<0x9A>', '<0x94>', ',', '▁', '<0xEC>', '<0x98>', '<0xA4>', '<0xEB>', '<0x8A>', '<0x98>', '은', '▁', '<0xEB>', '<0x82>', '<0xA0>', '<0xEC>', '<0x94>', '<0xA8>', '가', '▁', '<0xEC>', '<0xA2>', '<0x8B>', '<0xEB>', '<0x84>', '<0xA4>', '<0xEC>', '<0x9A>', '<0x94>', '.', '<0xE3>', '<0x85>', '<0x8E>', '<0xE3>', '<0x85>', '<0x8E>']` |
+| **Expanded Yi-Ko Series** | 10 | `['▁안녕', '하세요', ',', '▁오늘은', '▁날', '씨가', '▁좋네요', '.', 'ㅎ', 'ㅎ']` |
+|<small>*Equal Korean vocab with Llama-2-Ko Series</small>||
+
+**Tokenizing "Llama 2: Open Foundation and Fine-Tuned Chat Models"**
+
+| Model | # of tokens | Tokens |
+| --- | --- | --- |
+| Original Yi-Series | 21 | `['The', '▁Y', 'i', '▁series', '▁models', '▁are', '▁large', '▁language', '▁models', '▁trained', '▁from', '▁scratch', '▁by', '▁developers', '▁at', '▁', '0', '1', '.', 'AI', '.']` |

+|<small>*Equal Korean vocab with Llama-2-Ko Series</small>| | <small>*Since **Expanded Yi-Ko Series** prepends `_` at the beginning of the text(to ensure same tokenization for Korean sentences), it shows negilible difference for the first token on English tokenization. </small>|
