Qwen 3 Story Point Estimator - appceleratorstudio - titanium
This model is fine-tuned on issue descriptions from appceleratorstudio and tested on titanium for story point estimation.
Model Details
Base Model: Qwen 3
Training Project: appceleratorstudio
Test Project: titanium
Task: Story Point Estimation (Regression)
Architecture: PEFT (LoRA)
Tokenizer: Qwen BPE Tokenizer
Input: Issue titles
Output: Story point estimation (continuous value)
Usage
from transformers import AutoModelForSequenceClassification
from peft import PeftConfig, PeftModel
from transformers import AutoTokenizer
# Load peft config model
config = PeftConfig.from_pretrained("DEVCamiloSepulveda/33-Qwen3SP-appceleratorstudio-titanium")
# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained("DEVCamiloSepulveda/33-Qwen3SP-appceleratorstudio-titanium")
base_model = AutoModelForSequenceClassification.from_pretrained(
config.base_model_name_or_path,
num_labels=1,
torch_dtype=torch.float16,
device_map='auto'
)
model = PeftModel.from_pretrained(base_model, "DEVCamiloSepulveda/33-Qwen3SP-appceleratorstudio-titanium")
# Prepare input text
text = "Your issue description here"
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=20, padding="max_length")
# Get prediction
outputs = model(**inputs)
story_points = outputs.logits.item()
