Qwen 2.5 7B Instruct - Counseling Fine-tuned (LoRA)

This model is a fine-tuned version of Qwen/Qwen2.5-7B-Instruct using LoRA on a counseling conversations dataset.

🎯 Model Description

This model has been fine-tuned to provide empathetic and professional counseling responses. It's designed to assist with emotional support and guidance in conversations.

⚠️ Important Disclaimer: This model is for educational and research purposes only. It should NOT replace professional mental health services, therapy, or crisis intervention.

🚀 Usage

Installation

pip install unsloth transformers

Basic Usage

from unsloth import FastLanguageModel

# Load model
model, tokenizer = FastLanguageModel.from_pretrained(
    model_name="Ibrahim-AI-dev/mental-health-counseling-chatbot",
    max_seq_length=2048,
    dtype=None,
    load_in_4bit=True,
)

# Enable inference mode
FastLanguageModel.for_inference(model)

# Create messages
messages = [
    {"role": "system", "content": "You are a professional counselor providing empathetic and helpful responses."},
    {"role": "user", "content": "I'm feeling anxious about my future. What should I do?"}
]

# Generate response
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")

outputs = model.generate(
    **inputs,
    max_new_tokens=512,
    temperature=0.7,
    do_sample=True,
    top_p=0.9,
)

response = tokenizer.decode(outputs[0][inputs['input_ids'].shape[1]:], skip_special_tokens=True)
print(response)

Advanced Usage with Custom Parameters

# More creative responses
outputs = model.generate(
    **inputs,
    max_new_tokens=512,
    temperature=0.9,  # Higher = more creative
    top_p=0.95,
    top_k=50,
    repetition_penalty=1.1,
)

# More focused responses
outputs = model.generate(
    **inputs,
    max_new_tokens=512,
    temperature=0.3,  # Lower = more focused
    top_p=0.85,
    do_sample=True,
)

💾 Model Size

• —Full Base Model: ~14 GB (required separately)
• —Merged Model: Available at Ibrahim-AI-dev/mental-health-counseling-chatbot-merged (if uploaded)

🎓 Training Configuration

- Learning Rate: 2e-4
- Batch Size: 2 (effective: 8 with gradient accumulation)
- Gradient Accumulation Steps: 4
- Optimizer: AdamW 8-bit
- Max Sequence Length: 2048

📈 Intended Use Cases

• —Research in conversational AI for mental health
• —Educational demonstrations of fine-tuning techniques
• —Prototyping counseling chatbot applications
• —Studying empathetic response generation

⚠️ Limitations

• —NOT a replacement for professional mental health care
• —May not handle crisis situations appropriately
• —Trained on specific conversation patterns and may not generalize to all scenarios
• —Should be used with human oversight
• —May occasionally generate inappropriate or incorrect responses
• —Limited to text-based interaction

🔒 Ethical Considerations

• —Always inform users they are interacting with an AI
• —Provide crisis hotline information for emergencies
• —Monitor outputs for harmful content
• —Do not use for diagnosis or treatment
• —Respect user privacy and confidentiality
