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 is the base-model pretrained on general text completion. On it's own, it isn't very useful, but it can be fine-tuned for specific tasks (instruct, chat, QA, and more).
You can access the instruct-tuned model here.
Sample usage (for text completion):
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
tokenizer = AutoTokenizer.from_pretrained('dicta-il/dictalm-7b')
model = AutoModelForCausalLM.from_pretrained('dicta-il/dictalm-7b', trust_remote_code=True).cuda()
model.eval()
with torch.inference_mode():
# this prompt was taken from the headline of a [YNet](https://www.ynet.co.il/architecture/article/b1j3bzcrn) article.
prompt = 'ืื ืืจื ืืืืืข ืื ืืืืกืืช ืืืงืืืงื ืคืืกืืืง: ืืฆืฆื'
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 samplign 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', 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', 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', trust_remote_code=True, use_flash_attention=True)
