**Update Log**
- 2024.05.16: Released Solar-Ko-Recovery
# **Solar-Ko-Recovery** 🌟❤️🩹
Solar-Ko-Recovery aimed to recover Solar's capability on Korean with re-arrange of Embeddings and LM head, featuring an expanded vocabulary and the inclusion of a Korean+English corpus for enhanced representation.
## Model Details
**Model Developers:** Junbum Lee (Beomi)
**Variations:** Solar-Ko-Recovery is available with one parameter sizes — 10.8B.
**Input:** The model accepts only text input.
**Output:** The model produces text output exclusively.
**Model Architecture:**
Solar-Ko-Recovery is an auto-regressive language model that leverages an optimized transformer architecture derived from Llama-2.
| |Training Data|Parameters|Content Length|GQA|Tokens|Learning Rate|
|---|---|---|---|---|---|---|
|Solar-Ko-Recovery|*A curated mix of Korean+English Corpora*|10.8B|4k|O|>30B*|5e<sup>-5</sup>|
> NOTE: Only Embedding layer and LM Head layer are trained.
**Vocab Expansion**
Vocab expansion is conducted on edited [upstage/solar-1-mini-tokenizer](https://huggingface.co/upstage/solar-1-mini-tokenizer), which is superset of Solar tokenizer.
| Model Name | Vocabulary Size | Description |
| --- | --- | --- |
| Original Solar | 32000 | Sentencepiece BPE |
| **solar-1-mini-tokenizer** | 64000 | Sentencepiece BPE. Added Ko/JP vocabs |
**Tokenizing "안녕하세요, 오늘은 날씨가 좋네요."**
- SOLAR-10.7B: 26 tokens
- Solar-Ko-Recovery: 7 tokens
| Model | Tokens |
| --- | --- |
| SOLAR-10.7B | `['▁', '안', '<0xEB>', '<0x85>', '<0x95>', '하', '세', '요', ',', '▁', '오', '<0xEB>', '<0x8A>', '<0x98>', '은', '▁', '날', '<0xEC>', '<0x94>', '<0xA8>', '가', '▁', '좋', '네', '요', '.']` |
| Solar-Ko-Recovery | `['▁안녕하세요', ',', '▁오늘은', '▁날씨가', '▁좋', '네요', '.']` |
**Tokenizing "Meet 10.7B Solar: Elevating Performance with Upstage Depth UP Scaling!"**
- SOLAR-10.7B: 22 tokens
- Solar-Ko-Recovery: 22 tokens
| Model | Tokens |
