	# InterleaveThinker-Critic Model

	This repository contains the InterleaveThinker-Critic-8B model presented in [InterleaveThinker: Reinforcing Agentic Interleaved Generation]().

	[Project Page]() \| [GitHub Repository](https://github.com/zhengdian1/InterleaveThinker) \| [Paper]()

	# 👀 Intro

	<div align="center">
	<img src="https://github.com/zhengdian1/InterleaveThinker/blob/main/assets/teaser.jpg?raw=true" alt="InterleaveThinker Teaser" width="80%">
	</div>

	We introduce InterleaveThinker, as the first multi-agent pipeline designed to endow any existing image generator with interleaved generation capabilities. InterleaveThinker can organize the image-text input sequence via a planner agent, evaluate generator outputs, identify deviations, and refine instructions via a critic agent, enabling complex interleaved text-image sequence generation for visual narratives, guidance, embodied manipulation and long-horizon sub-task annotation.

	We build three dedicated training datasets—Interleave-Planner-SFT-80k, Interleave-Critic-SFT-112k, and Interleave-Critic-RL-13k—for interleaved generation and step-wise instruction correction using GRPO with proposed accuracy and step-wise rewards.

	InterleaveThinker achieves performance comparable to Nano Banana and GPT-5 on interleaved generation benchmarks, delivering substantial gains on reasoning-based benchmarks (e.g., boosting WISE from 0.47 to 0.74 and RISE from 13.3 to 28.9 on 4-step FLUX.2-klein). It also demonstrates strong transferability, improving performance across various existing image generators.
