This is a [Mistral7B](https://huggingface.co/mistralai/Mistral-7B-v0.1) model fine-tuned with 4bit-QLoRA on Czech Wikipedia data. The model is primarily designed for further fine-tuning for Czech-specific NLP tasks, including summarization and question answering. This adaptation allows for better performance in tasks that require an understanding of the Czech language and context.

For exact QLoRA parameters, see the Axolotl's  [YAML file](cswiki-mistral7.yml).

**Example of usage:**:

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_name = "simecek/cswikimistral_0.1"
device = "cuda" if torch.cuda.is_available() else "cpu"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name, device_map="auto", load_in_4bit=True)

def generate_text(prompt, max_new_tokens=50):
    inputs = tokenizer(prompt, return_tensors="pt").to(device)
    attention_mask = inputs["attention_mask"]
    input_ids = inputs["input_ids"]
    
    output = model.generate(
        input_ids,
        attention_mask=attention_mask,
        max_new_tokens=max_new_tokens,
        num_return_sequences=1,
        pad_token_id=tokenizer.eos_token_id,
    )
    
    return tokenizer.decode(output[0], skip_special_tokens=True)

prompt = "Hlavní město České republiky je"
generated_text = generate_text(prompt, max_new_tokens=5)
print(generated_text)
```
