To construct Hunyuan-DiT, we carefully design the transformer structure, text encoder, and positional encoding. We also build from scratch a whole data pipeline to update and evaluate data for iterative model optimization. For fine-grained language understanding, we train a Multimodal Large Language Model to refine the captions of the images. Finally, Hunyuan-DiT can perform multi-turn multimodal dialogue with users, generating and refining images according to the context. Through our holistic human evaluation protocol with more than 50 professional human evaluators, Hunyuan-DiT sets a new state-of-the-art in Chinese-to-image generation compared with other open-source models.</em></p> <p>You can find the original codebase at <a href="https://github.com/Tencent/HunyuanDiT" rel="nofollow">Tencent/HunyuanDiT</a> and all the available checkpoints at <a href="https://huggingface.co/Tencent-Hunyuan/HunyuanDiT" rel="nofollow">Tencent-Hunyuan</a>.</p> <p><strong>Highlights</strong>: HunyuanDiT supports Chinese/English-to-image, multi-resolution generation.</p> <p>HunyuanDiT has the following components:</p> <ul><li>It uses a diffusion transformer as the backbone</li> <li>It combines two text encoders, a bilingual CLIP and a multilingual T5 encoder</li></ul> <blockquote class="tip"><p>Make sure to check out the Schedulers <a href="../../using-diffusers/schedulers">guide</a> to learn how to explore the tradeoff between scheduler speed and quality, and see the <a href="../../using-diffusers/loading#reuse-a-pipeline">reuse components across pipelines</a> section to learn how to efficiently load the same components into multiple pipelines.</p></blockquote> <blockquote class="tip"><p>You can further improve generation quality by passing the generated image from <code>HungyuanDiTPipeline</code> to the <a href="./stable_diffusion/stable_diffusion_xl#base-to-refiner-model">SDXL refiner</a> model.</p></blockquote> <!> <p>You can optimize the pipeline’s runtime and memory consumption with torch.compile and feed-forward chunking.
