+# Re:Form: Reducing Human Priors in Scalable Formal Software Verification with RL in LLMs
+
+This repository contains a model from the **Re:Form** framework, presented in the paper [Re:Form -- Reducing Human Priors in Scalable Formal Software Verification with RL in LLMs: A Preliminary Study on Dafny](https://huggingface.co/papers/2507.16331).
+
+**Re:Form** is a novel approach that addresses the challenges of unreliable and unscalable verification processes in Large Language Models (LLMs) that typically operate with informal languages. It proposes grounding LLMs in rigorous formal systems, specifically using the Dafny formal language, to enable automatic and mathematically provable verification of their reasoning processes and outcomes. This capability is pivotal for achieving large-scale, reliable formal software verification.

+## Overview
+
+The `Re:Form` pipeline focuses on reducing human priors in complex programming tasks through an automatic and scalable data curation pipeline. It integrates careful Reinforcement Learning (RL) designs with feedback from a formal language verifier. This methodology allows even small models (e.g., 0.5B) to generate syntactically valid and verifiable Dafny code, surpassing proprietary models and demonstrating stronger generalization to out-of-domain tasks, including on the challenging DafnyComp benchmark.

+
+## Usage
+
+You can load and use the `Re:Form` models with the Hugging Face `transformers` library. The model uses the `Qwen2ForCausalLM` architecture.
+
+Here's an example of how to perform text generation for Dafny code:
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+import torch
+
+# Replace "Veri-Code/sft_7B" with the specific model checkpoint you want to load
+# e.g., "Veri-Code/sft_0.5B", "Veri-Code/sft_1.5B", "Veri-Code/sft_3B", "Veri-Code/sft_14B", or "Veri-Code/14B-RL-entropy"
+model_id = "Veri-Code/sft_7B" 
+
+tokenizer = AutoTokenizer.from_pretrained(model_id)
+model = AutoModelForCausalLM.from_pretrained(
+    model_id,
+    torch_dtype=torch.bfloat16, # Adjust dtype based on your hardware (e.g., torch.float16 for GPUs without bfloat16 support)
+    device_map="auto"
+)
+
+# Example: Generate Dafny code for a function that returns the absolute value
+dafny_prompt = """function Abs(x: int): int
+ensures Abs(x) >= 0
+{
+"""
+
+inputs = tokenizer.apply_chat_template([{"role": "user", "content": dafny_prompt}], return_tensors="pt", add_generation_prompt=True)
+outputs = model.generate(inputs.to(model.device), max_new_tokens=100)
+generated_text = tokenizer.decode(outputs[0], skip_special_tokens=True)
+
+print(generated_text)
+```
