# Maestrale chat beta ༄
|
|
|
|
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.
|
|
- **Fine-Tuning**: SFT performed on convs/instructions for three epochs.
|
|
- **KTO**: Aligned with KTO.
|
|
|
|
**v0.3**
|
|
- Function calling
|
|
- Reduced default system prompt to avoid wasting tokens (pre-alignment)
|
|
|
|
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-v0.3-beta")
|
|
model = AutoModelForCausalLM.from_pretrained("mii-llm/maestrale-chat-v0.3-beta", 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 a beta version, but it's not `safe`.
