# Maestrale chat alpha ༄

By @efederici and @mferraretto

## Model description

- **Language Model**: Mistral-7b for the Italian language, continued pre-training for Italian on a curated large-scale high-quality corpus, merged with [occiglot](https://huggingface.co/occiglot/occiglot-7b-eu5). 
- **Fine-Tuning**: SFT performed on 1.7M convs/instructions for 2 epochs.

**v0.4**
- Agent
- Improved truthfullness
- Improved Math & Reasoning capabilities
- Mermaid mindmaps
- More latin translations, poems, ...

This model uses ChatML prompt format:
```
<|im_start|>system
Sei un assistente utile.<|im_end|>
<|im_start|>user
{prompt}<|im_end|>
<|im_start|>assistant
```

## Usage:

```python
from transformers import (
    AutoTokenizer, 
    AutoModelForCausalLM, 
    GenerationConfig,
    TextStreamer
)
import torch

tokenizer = AutoTokenizer.from_pretrained("mii-llm/maestrale-chat-v0.4-alpha-sft")
model = AutoModelForCausalLM.from_pretrained("mii-llm/maestrale-chat-v0.4-alpha-sft", load_in_8bit=True, device_map="auto")

gen = GenerationConfig(
    do_sample=True,
    temperature=0.7,
    repetition_penalty=1.2,
    top_k=50,
    top_p=0.95,
    max_new_tokens=500,
    pad_token_id=tokenizer.eos_token_id,
    eos_token_id=tokenizer.convert_tokens_to_ids("<|im_end|>")
)

streamer = TextStreamer(tokenizer, skip_prompt=True)

messages = [
    {"role": "system", "content": "Sei un assistente utile."},
    {"role": "user", "content": "{prompt}"}
]

with torch.no_grad():
    temp = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
    inputs = tokenizer(temp, return_tensors="pt").to("cuda")

    _ = model.generate(
        **inputs,
        streamer=streamer,
        generation_config=gen
    )
```

## Intended uses & limitations

It's an alpha version; it's not `safe`, but it can refuse to answer.
