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 or the technical report.

This model contains the GPTQ 4-bit quantized version of the base model DictaLM-2.0.

You can view and access the full collection of base/instruct unquantized/quantized versions of DictaLM-2.0 here.

Example Code

Running this code requires ~5.1GB of GPU VRAM.

from transformers import pipeline

# This loads the model onto the GPU in bfloat16 precision
model = pipeline('text-generation', 'dicta-il/dictalm2.0-GPTQ', 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=4, 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'}]

Model Architecture

DictaLM-2.0 is based on the Mistral-7B-v0.1 model with the following changes:

• An extended tokenizer with tokens for Hebrew, increasing the compression ratio
• 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.

Notice

DictaLM 2.0 is a pretrained base model and therefore does not have any moderation mechanisms.
