## Improvements from v1:
- Extended Training: Further refinement of the model, resulting in improved benchmark performance and overall text generation quality.
- Tokenizer changes.

## How coherent is the 150M model?
Let's look at real-world examples:

## Example 1
```
Input:
<s>user
What is the capital of France?</s> 
<s>assistant
The capital of France is Paris.</s> 
<s>user
What is the capital of Spain?</s>

Response:
<s>assistant
The capital of Spain is Madrid, which is known for its beautiful architecture and rich history.</s>
```

## Example 2
```
Input:
<s>user
Who wrote the play "Romeo and Juliet"?</s>

Response:
<s>assistant
The play "Romeo and Juliet" was written by William Shakespeare.</s>
```

## Example 3
```
Input:
<s>user
Tell me a joke</s>

Response:
<s>assistant
Why did the chicken cross the playground? Because it wanted to see who could get the ball!</s>
```

## Example 4 (RP)
```
Input:
<s>user
Let's roleplay. I'll be a customer at a restaurant, and you be the waiter. Ready?</s> 
<s>assistant
Certainly! I'll play the role of a waiter. Please go ahead and start the roleplay when you're ready.</s> 
<s>user
Hello, I'd like to see the menu please.</s> 
<s>assistant
Good evening, sir! Welcome to our restaurant. Here's our menu for today. May I recommend our chef's special, the grilled salmon with lemon butter sauce? Let me know if you have any questions about our dishes.</s> 
<s>user
I'll have the salmon. What wines do you recommend to go with it?</s> 

Response:
<s> assistant
To go with your salmon, we suggest a pair of red-tailed or white-tailed jackfights. The grilled salmon is creamy and has a nice acidity. The lemon butter sauce is a great addition to this dish.</s>
```

While the model performs well for straightforward tasks, it may lack depth in complex topics or sophisticated creative abilities.
It's optimized for scenarios where computational efficiency is paramount.
As a lightweight model, it may exhibit reduced accuracy and coherence compared to larger language models.

## Chat format

This model uses a specific chat format for optimal performance.
```
<s>system
[System message]</s>
<s>user
[Your question or message]</s> 
<s>assistant
[The model's response]</s>
```

## Usage with HuggingFace transformers 
The model can be used with HuggingFace's `transformers` library:
```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("OuteAI/Lite-Mistral-150M-v2-Instruct")
tokenizer = AutoTokenizer.from_pretrained("OuteAI/Lite-Mistral-150M-v2-Instruct")

def generate_response(message):
    # Encode the formatted message as input ids
    input_ids = tokenizer.encode(f"<s>user\n{message}</s>", return_tensors="pt")
    output = model.generate(input_ids, max_length=100, pad_token_id=tokenizer.eos_token_id)

    # Decode the generated output
    generated_text = tokenizer.decode(output[0], skip_special_tokens=True)
    
    return generated_text

message = "What is the capital of Spain?"
response = generate_response(message)
```
