|
|
### Model Description |
|
|
|
This model is created for answering the KUET(Khulna University of Engineering & Technology) information. |
|
|
|
- **Developed by:** Md. Shahidul Salim |
|
- **Model type:** Question answering |
|
- **Language(s) (NLP):** English |
|
- **Finetuned from model:** mistralai/Mistral-7B-Instruct-v0.1 |
