🧠 Zigroo Mental Consultant 2 (Merged)

alibidaran/Zigroo-Mental_consultant2-merged

A fine-tuned large language model designed to provide empathetic, therapeutically-informed conversational support. Built on top of Qwen3-8B, this model was trained in two stages — Supervised Fine-Tuning (SFT) across five curated mental health datasets, followed by Direct Preference Optimization (DPO) to align responses toward reliable, compassionate, and therapeutically grounded outputs.

⚠️ Disclaimer: This model is intended for research and educational purposes only. It is not a substitute for professional mental health care, diagnosis, or treatment. If you or someone you know is in crisis, please contact a licensed mental health professional or a crisis helpline immediately.

🏋️ Training Pipeline

Stage 1 — Supervised Fine-Tuning (SFT)

The model was fine-tuned using a LoRA adapter (rank = 32) on five mental health and therapy datasets covering a wide range of therapeutic modalities:

Dataset	Description
vibhorag101/phr-mental-therapy-dataset-conversational-format-1024-tokens	Conversational mental therapy dialogues formatted to 1024 tokens
Ghani69/ACT_therapy_scripts	Acceptance and Commitment Therapy (ACT) scripts
to-be/annomi-motivational-interviewing-therapy-conversations	Motivational interviewing therapy conversations
fadodr/mental_health_therapy	General mental health therapy dialogues
arafatanam/Student-Mental-Health-Counseling-50K	50K student mental health counseling conversations

Stage 2 — Direct Preference Optimization (DPO)

Following SFT, the model underwent DPO training to align its outputs with preferred therapeutic response styles, improving reliability, empathy, and safety of generated responses.

Dataset	Description
jkhedri/psychology-dataset	Psychology-grounded preference pairs for DPO alignment

🚀 Usage

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "alibidaran/Zigroo-Mental_consultant2-merged"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

prompt = "I've been feeling very anxious lately and I don't know how to cope."

messages = [
    {"role": "user", "content": prompt}
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)

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

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

4-bit Quantized Inference (recommended for limited VRAM)

from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig
import torch

model_id = "alibidaran/Zigroo-Mental_consultant2-merged"

bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_compute_dtype=torch.bfloat16
)

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    quantization_config=bnb_config,
    device_map="auto"
)

⚙️ LoRA Configuration

This model was trained with a LoRA adapter and the weights have been merged into the base model for ease of deployment. The key LoRA hyperparameters used during training:

• Rank (r): 32
• Base model: Qwen3-8B (via Unsloth 4-bit quantized variant)
• Merged: ✅ LoRA weights fully merged into base model

---

🎯 Intended Use

• Research into LLM-based therapeutic conversational agents
• Prototyping mental health support chatbots
• Studying multi-stage fine-tuning pipelines (SFT + DPO) for sensitive domains
• Educational exploration of therapeutic dialogue generation

❌ Out-of-Scope Use

• Clinical diagnosis or treatment decisions
• Crisis intervention without human oversight
• Replacement of licensed therapists or psychiatrists
• Any deployment involving vulnerable populations without professional supervision

⚠️ Ethical Considerations & Safety

Mental health is a sensitive domain. Please be aware of the following:

• Not a therapist. This model does not possess clinical judgment and should never be used as a standalone mental health service.
• Hallucinations. Like all LLMs, this model can generate plausible-sounding but incorrect or harmful content.
• Bias. Training datasets may reflect biases in how mental health topics are framed; outputs should be reviewed critically.
• Crisis situations. This model is not equipped to handle acute crisis situations. Always redirect users in crisis to emergency services or licensed professionals.
