Update @ 2024.01.29 New Model beomi/Yi-Ko-DUS-9B Released! 🎉
Update @ 2023.12.03 Yi-Ko(KoEN)-6B Achieved #1🥇 Pretrained Models at Open Korean LLM Leaderboard! 🎉
Update @ 2023.12.01 Alpha Release of Yi-Ko(KoEN)-6B model 🎉
beomi/Yi-Ko-6B
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*.
*Yi model architecture is based on Llama2, so it can be loaded via LlamaForCausalLM class on HF.
| Model Name | Training Data | Params | Context Length | GQA | Trained Tokens | LR | Batch Size(per step) |
|---|---|---|---|---|---|---|---|
| Yi-Ko-6B | A mix of Korean + English online data | 6B | 4k | O | >60B | 5e-5 | 2048 |
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'] |
| *Equal Korean vocab with Llama-2-Ko Series |
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', '.'] |
| Expanded Yi-Ko Series | 21 | ['▁The', '▁Y', 'i', '▁series', '▁models', '▁are', '▁large', '▁language', '▁models', '▁trained', '▁from', '▁scratch', '▁by', '▁developers', '▁at', '▁', '0', '1', '.', 'AI', '.'] |
| *Equal Korean vocab with Llama-2-Ko Series | *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. |
