# Gen-Searcher SFT Model

This repository contains the Supervised Fine-Tuning (SFT) model presented in the paper: [Gen-Searcher: Reinforcing Agentic Search for Image Generation](https://arxiv.org/abs/2603.28767).

This is an intermediate model prepared for subsequent reinforcement learning (RL) training using the GRPO algorithm with dual reward feedback.

We introduce **Gen-Searcher**, as the first attempt to train a multimodal **deep research agent** for image generation that requires complex real-world knowledge. Gen-Searcher can **search the web, browse evidence, reason over multiple sources, and search visual references** before generation, enabling more accurate and up-to-date image synthesis in real-world scenarios.

We build two dedicated training datasets **Gen-Searcher-SFT-10k**, **Gen-Searcher-RL-6k** and one new benchmark **KnowGen** for search-grounded image generation. 

Gen-Searcher achieves significant improvements, delivering **15+ point gains on the KnowGen and WISE benchmarks**. It also demonstrates **strong transferability** to various image generators.

All code, models, data, and benchmark are fully released.
