# finetune-indoMMLU-Merak-7B-v4
Based on Merak-7B-v4 Mistral: https://huggingface.co/Ichsan2895/Merak-7B-v4<br>
Dataset used on Fine Tuning: https://github.com/fajri91/IndoMMLU
<br>

Some training params used:
```python
lora r=64
lora_alpha=16
lora_dropout=0.05

learning_rate = 2e-4
lr_scheduler = "constant"
optimizer = "paged_adamw_32bit"
max_seq_length = 2048
```

Inference:
```python
