🚀 PIPer: On-Device Environment Setup via Online Reinforcement Learning

Models

Dataset

License

Democratizing environment setup with on-device sized models that match the performance of much larger proprietary systems

🎯 Overview

Environment setup—the process of configuring systems to work with specific software projects—remains a persistent challenge in software engineering. PIPer addresses this by training specialized on-device models that can automatically generate correct Bash scripts for environment configuration.

Our approach combines:

📚 Supervised Fine-Tuning (SFT) with executable scripts from larger models
🎯 Reinforcement Learning with Verifiable Rewards (RLVR) using lightweight proxy LLM-reward

🏆 Key Results

Model	Size	EnvBench avg@5	Cost per 1M tokens
PIPer	8B	19.4	$0.60
GPT-4o	-	19.4	$15.00
Qwen3-32B	32B	16.2	$2.00
Qwen3-8B	8B	2.6	$0.60

🎉 PIPer achieves 9× improvement over its base model while matching GPT-4o performance at 25x lower cost
