Aya Expanse 8B Mkd_Cyrl

Language-enhanced Aya-Expanse-8b model for Macedonian using sparse subnetwork fine-tuning.

Method

• Training approach: Language-specific neuron identification + subnetwork fine-tuning
• Parameters trained: <1% of total model parameters
• Framework: Language Subnetwork Enhancement

Performance

Enhanced monolingual capabilities in Macedonian while preserving multilingual performance.

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("DGurgurov/aya-expanse-8b-mkd_cyrl")
tokenizer = AutoTokenizer.from_pretrained("DGurgurov/aya-expanse-8b-mkd_cyrl")

prompt = "Your Macedonian prompt here"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_length=100)
print(tokenizer.decode(outputs[0]))
