🧠 Dia-Convo-v1.2c

petrioteer/dia-convo-v1.2c is a conversational mental-health-focused LLM designed for Gen Z, built on top of Qwen2.5-7B-Instruct and fine-tuned using dia-therapy-dataset. This model powers Dia-Therapist, an empathetic AI that offers mental health support while being context-aware, brief, and emotionally intelligent.

---

💬 Intended Use

This model is tuned to offer:

• Thoughtful responses to mental health queries
• Conversational tone suited for Gen Z
• Non-medical, non-clinical guidance
• Short, contextually sensitive replies

It does not replace professional therapy.

📚 Training Dataset

• anupamaditya/dia-therapy-dataset
• Contains conversational instructions paired with realistic mental-health-related inputs from Gen Z users.

🧪 Example Inference (🤗 Transformers)

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_name = "petrioteer/dia-convo-v1.2c"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    device_map="auto",
    torch_dtype=torch.float16
)

prompt = """
### Instruction:
Your name is Dia, a mental health therapist Assistant Bot. Provide guidance on mental health topics only and avoid others. Don\'t give medical advice. Keep responses short and relevant.

### Input:
I'm feeling overwhelmed with my classes. I can't seem to focus.

### Response:
"""

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=100,
    temperature=0.3,
    top_p=0.85,
    top_k=40,
    do_sample=True,
    eos_token_id=tokenizer.eos_token_id,
)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))
