Model Card for BiMediX-Bilingual
Model Details
- Name: BiMediX
- Version: 1.0
- Type: Bilingual Medical Mixture of Experts Large Language Model (LLM)
- Languages: Arabic
- Model Architecture: Mixtral-8x7B-Instruct-v0.1
- Training Data: BiMed1.3M-Arabic, an arabic dataset with diverse medical interactions.
Intended Use
- Primary Use: Medical interactions in both English and Arabic.
- Capabilities: MCQA, closed QA and chats.
Getting Started
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "BiMediX/BiMediX-Ara"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)
text = "مرحبًا بيميديكس! لقد كنت أعاني من التعب المتزايد في الأسبوع الماضي."
inputs = tokenizer(text, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=500)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
Training Procedure
- Dataset: BiMed1.3M-Arabic.
- QLoRA Adaptation: Implements a low-rank adaptation technique, incorporating learnable low-rank adapter weights into the experts and the routing network. This results in training about 4% of the original parameters.
- Training Resources: The model underwent training on the Arabic corpus.

visibility and check back later, or deploy to Inference Endpoints (dedicated)
instead.
