ReframeBot-SFT-Llama3.1-8B

ReframeBot-SFT-Llama3.1-8B

LoRA adapter for meta-llama/Meta-Llama-3.1-8B-Instruct, fine-tuned with Supervised Fine-Tuning (SFT) to support CBT-style Socratic questioning for university students under academic stress.

This is stage 1 of the ReframeBot training pipeline. The DPO adapter (ReframeBot-DPO-Llama3.1-8B) was initialised from this checkpoint.

Usage

from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig
from peft import PeftModel
import torch

base = "meta-llama/Meta-Llama-3.1-8B-Instruct"
adapter = "Nhatminh1234/ReframeBot-SFT-Llama3.1-8B"

bnb = BitsAndBytesConfig(load_in_4bit=True, bnb_4bit_compute_dtype=torch.bfloat16)
tokenizer = AutoTokenizer.from_pretrained(base)
model = AutoModelForCausalLM.from_pretrained(base, quantization_config=bnb, device_map="auto")
model = PeftModel.from_pretrained(model, adapter)

Training Details

Dataset: 4,500 synthetic multi-turn dialogues generated with GPT-4, covering academic stress scenarios (exam anxiety, GPA pressure, deadline overwhelm, imposter syndrome, burnout). All conversations follow CBT Socratic questioning patterns.

Intended Use

Designed as a component in the ReframeBot system — not a standalone mental-health tool. Must not be used for clinical intervention or crisis support without human oversight.
