DictaLM: A Large Generative Language Model for Modern Hebrew
A large generative pretrained transformer (GPT) language model for Hebrew, released here.
- This is an alpha version of the model, and there are many improvements to come.
- We are actively working on improving the model, so stay tuned.
This model was fine-tuned for instructions, here are a few examples of the different types of instructions the model was trained on:

Sample usage:
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
tokenizer = AutoTokenizer.from_pretrained('dicta-il/dictalm-7b-instruct')
model = AutoModelForCausalLM.from_pretrained('dicta-il/dictalm-7b-instruct', trust_remote_code=True).cuda()
model.eval()
with torch.inference_mode():
prompt = 'ืชืฆืืข ืืื ืจืขืืื ืืช ืืคืขืืืืช ืขื ืืืืื ืื ื 5:\n'
kwargs = dict(
inputs=tokenizer(prompt, return_tensors='pt').input_ids.to(model.device),
do_sample=True,
top_k=50,
top_p=0.95,
temperature=0.75,
max_length=100,
min_new_tokens=5
)
print(tokenizer.batch_decode(model.generate(**kwargs), skip_special_tokens=True))
There are many different parameters you can input into kwargs
for different results (greedy, beamsearch, different sampling configurations, longer/shorter respones, etc.).
You can view the full list of parameters you can pass to the generate
function here.
Alternative ways to initialize the model:
If you have multiple smaller GPUs, and the package accelerate
is installed, you can initialize the model split across the devices:
model = AutoModelForCausalLM.from_pretrained('dicta-il/dictalm-7b-instruct', trust_remote_code=True, device_map='auto')
If you are running on linux and have the bitsandbytes
package installed, you can initialize the model in 4/8 bit inference mode:
model = AutoModelForCausalLM.from_pretrained('dicta-il/dictalm-7b-instruct', trust_remote_code=True, load_in_8bit=True)
If you have FlashAttention installed in your environment, you can instruct the model to use the flash attention implementation (either V1 or V2, whichever is installed):
model = AutoModelForCausalLM.from_pretrained('dicta-il/dictalm-7b-instruct', trust_remote_code=True, use_flash_attention=True)
Colab notebook demos
You can try the model on a free tier google colab using the following notebooks:
- Streamlit based - you will need first to log in https://ngrok.com/ and get an authtoken, then paste it in the notebook (screenshot).
- Gradio based - uses deep speed for faster inference, text streamer to get the results as they are being generated and the UI is a widget embedded in the notebook (screenshot).
