# Adapting LLMs to Hebrew: Unveiling DictaLM 2.0 with Enhanced Vocabulary and Instruction Capabilities
|
||
|
||
The DictaLM-2.0 Large Language Model (LLM) is a pretrained generative text model with 7 billion parameters trained to specialize in Hebrew text.
|
||
|
||
For full details of this model please read our [release blog post](https://dicta.org.il/dicta-lm) or the [technical report](https://arxiv.org/abs/2407.07080).
|
||
|
||
This is the full-precision base model.
|
||
You can view and access the full collection of base/instruct unquantized/quantized versions of `DictaLM-2.0` [here](https://huggingface.co/collections/dicta-il/dicta-lm-20-collection-661bbda397df671e4a430c27).
|
||
|
||
## Example Code
|
||
|
||
```python
|
||
from transformers import pipeline
|
||
import torch
|
||
|
||
# This loads the model onto the GPU in bfloat16 precision
|
||
model = pipeline('text-generation', 'dicta-il/dictalm2.0', torch_dtype=torch.bfloat16, device_map='cuda')
|
||
|
||
# Sample few shot examples
|
||
prompt = """
|
||
עבר: הלכתי
|
||
עתיד: אלך
|
||
|
||
עבר: שמרתי
|
||
עתיד: אשמור
|
||
|
||
עבר: שמעתי
|
||
עתיד: אשמע
|
||
|
||
עבר: הבנתי
|
||
עתיד:
|
||
"""
|
||
|
||
print(model(prompt.strip(), do_sample=False, max_new_tokens=8, stop_sequence='\n'))
|
||
# [{'generated_text': 'עבר: הלכתי\nעתיד: אלך\n\nעבר: שמרתי\nעתיד: אשמור\n\nעבר: שמעתי\nעתיד: אשמע\n\nעבר: הבנתי\nעתיד: אבין\n\n'}]
|
||
```
|
||
|
||
## Example Code - 4-Bit
|
||
|
||
There are already pre-quantized 4-bit models using the `GPTQ` and `AWQ` methods available for use: [DictaLM-2.0-AWQ](https://huggingface.co/dicta-il/dictalm2.0-AWQ) and [DictaLM-2.0-GPTQ](https://huggingface.co/dicta-il/dictalm2.0-GPTQ).
|
||
|
||
For dynamic quantization on the go, here is sample code which loads the model onto the GPU using the `bitsandbytes` package, requiring :
|
||
|
||
```python
|
||
from transformers import AutoModelForCausalLM, AutoTokenizer
|
||
import torch
|
||
|
||
model = AutoModelForCausalLM.from_pretrained('dicta-il/dictalm2.0', torch_dtype=torch.bfloat16, device_map='cuda', load_in_4bit=True)
|
||
tokenizer = AutoTokenizer.from_pretrained('dicta-il/dictalm2.0')
|
||
|
||
prompt = """
|
||
עבר: הלכתי
|
||
עתיד: אלך
|
||
|
||
עבר: שמרתי
|
||
עתיד: אשמור
|
||
|
||
עבר: שמעתי
|
||
עתיד: אשמע
|
||
|
||
עבר: הבנתי
|
||
עתיד:
|
||
"""
|
||
|
||
encoded = tokenizer(prompt.strip(), return_tensors='pt').to(model.device)
|
||
print(tokenizer.batch_decode(model.generate(**encoded, do_sample=False, max_new_tokens=4)))
|
||
# ['<s> עבר: הלכתי\nעתיד: אלך\n\nעבר: שמרתי\nעתיד: אשמור\n\nעבר: שמעתי\nעתיד: אשמע\n\nעבר: הבנתי\nעתיד: אבין\n\n']
|
||
```
|
||
|
||
|
||
## Model Architecture
|
||
|
||
DictaLM-2.0 is based on the [Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1) model with the following changes:
|
||
- An extended tokenizer with 1,000 injected tokens specifically for Hebrew, increasing the compression rate from 5.78 tokens/word to 2.76 tokens/word.
|
||
- Continued pretraining on over 190B tokens of naturally occuring text, 50% Hebrew and 50% English.
|
||
|
||
## Notice
|
||
|
||
DictaLM 2.0 is a pretrained base model and therefore does not have any moderation mechanisms.
