Performance Improvements After Fine-Tuning

The fine-tuning process was evaluated using the NVIDIA Nemotron-4-340B-Reward model, which assesses AI-generated responses on five key attributes: helpfulness, correctness, coherence, complexity, and verbosity. Based on this reward model, the fine-tuning resulted in the following performance improvements:

• Helpfulness: Increased from 0.4343 to 0.6166.
• Correctness: Increased from 0.5546 to 0.8130.
• Coherence: Increased from 2.4018 to 2.5711.
• Complexity: Decreased from 1.0023 to 0.9118.
• Verbosity: Decreased from 1.4032 to 1.1779.

These results indicate that the fine-tuning process improved the model's ability to generate more helpful, correct, and coherent responses. The reduction in complexity and verbosity means that the model's outputs are easier to understand and use fewer words to convey the same message, which is a positive improvement.

Uses

Direct Use

The model can be directly used for generating coherent and contextually relevant responses to a wide range of prompts, particularly in scenarios where instruction-following is essential.

Out-of-Scope Use

This model should not be used for tasks that require deep reasoning or extensive context beyond the given prompt. Additionally, it is not suitable for applications requiring highly specialized knowledge unless further fine-tuned on relevant data.

Bias, Risks, and Limitations

As with all language models, this model may reflect biases present in its training data. Users should exercise caution when deploying the model in sensitive contexts and should consider further fine-tuning or bias mitigation strategies if needed.

How to Get Started with the Model

Use the code below to get started with the model:

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "AmirMohseni/SmolLM-360M-Instruct-finetuned-sft-v2"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Example usage
prompt = "Explain the process of photosynthesis."
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)

Training Details
