+# WebGen-Agent
+
+WebGen-Agent is an advanced website generation agent designed to autonomously create websites from natural language instructions. It was introduced in the paper [WebGen-Agent: Enhancing Interactive Website Generation with Multi-Level Feedback and Step-Level Reinforcement Learning](fig/WebGen_Agent.pdf).
+
+## Project Overview
+
+WebGen-Agent combines state-of-the-art language models with specialized training techniques to create a powerful website generation tool. The agent can understand natural language instructions specifying appearance and functional requirements, iteratively generate website codebases, and refine them using visual and functional feedback.
+

+## How WebGen-Agent Works
+
+WebGen-Agent follows an iterative, multi-step paradigm for website generation:
+
+1. **Code Generation**: The agent generates code to create or edit website files based on natural language instructions
+2. **Code Execution**: Dependencies are installed and the website service is started
+3. **Feedback Gathering**: 
+   - A screenshot of the website is captured
+   - A Visual Language Model (VLM) provides appearance feedback and scores
+   - A GUI-agent tests the website functionality and provides functional feedback
+4. **Refinement**: Based on the feedback, the agent continues to improve the website until it meets requirements

+
+## Step-GRPO with Screenshot and GUI-agent Feedback
+
+The Step-GRPO with Screenshot and GUI-agent Feedback approach uses the screenshot and GUI-agent scores inherently produced in the WebGen-Agent workflow as step-level rewards:
+- **Screenshot Score**: Quantifies the visual appeal and aesthetics of the website
+- **GUI-agent Score**: Measures how well the website meets functional requirements
+
+These dual rewards provide dense, reliable process supervision that significantly improves the model's ability to generate high-quality websites.
