CAP RLVR GRPO Model - Summarise Task

This model is a Group Relative Policy Optimization (GRPO) fine-tuned version of Qwen3-14B for legal reasoning tasks, specifically optimized for the summarise task.

Training Details

Base Model: Qwen/Qwen3-14B (via SFT checkpoint)
Task: summarise (legal summarise task)
Training Method: GRPO (Group Relative Policy Optimization)
Training Pairs: 755
Epochs: 3
Learning Rate: 5e-06
Final Loss: -0.0025146465063452376

Model Architecture

This is a LoRA (Low-Rank Adaptation) model that can be loaded with the base Qwen3-14B model.

Usage

python

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

# Load base model
base_model = AutoModelForCausalLM.from_pretrained("Qwen/Qwen3-14B")
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen3-14B")

# Load GRPO adapter
model = PeftModel.from_pretrained(base_model, "kylebrussell/cap-rlvr-grpo-summarise")

# Use for summarise tasks
inputs = tokenizer("Your summarise query here", return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=200)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)

Dataset

Trained on CAP RLVR (Caselaw Access Project - Reinforcement Learning with Value-based Rewards) dataset, focusing on legal reasoning tasks.
