Video Generation
Now post-training Seedance at ByteDance. Previously worked on video pretraining, post-training (camera control, editing), and alignment tuning.
Gordon Guocheng Qian is a Staff Researcher at ByteDance, where he works on post-training of Seedance video generation models. Previously, he was a Senior Research Scientist at Snap Inc., where he worked on video generation pretraining and post-training and served as tech lead for personalized generation, filing six patents and shipping three research innovations to Snapchat products (Dreams, EasyLens, and AI Lens), impacting 900M+ monthly active users. He earned his Ph.D. in Computer Science from KAUST, advised by Prof. Bernard Ghanem.
He has authored 20+ top-tier publications with 4,000+ citations.
His representative works include PointNeXt (NeurIPS, 1.2K+ citations, 1K+ GitHub stars), Magic123 (ICLR, 450+ citations, 1.6K+ GitHub stars), and Omni-ID (CVPR, product integrated, patent filed). His research interests include streamable and unified multimodal understanding and generation. He serves as an Area Chair for ICLR and NeurIPS.

Now post-training Seedance at ByteDance. Previously worked on video pretraining, post-training (camera control, editing), and alignment tuning.
Tech lead of full-stack R&D. Shipped three products and filed three patents.
Worked on VLM post-training, VLM diffusion, and VLM-based reward tuning.
Worked across image-to-3D and text-to-3D generation, including high-impact systems for geometry, mesh generation, and controllable 3D content.
First-authored multiple projects on scalable spatial understanding and efficient 3D representation learning.
Selected projects below; * / † denote equal contribution / corresponding author. See Full publication list .
Prompt2Effect synthesizes effect-specific LoRA weights for image-to-video diffusion models in a single forward pass, reducing per-effect specialization from 56 GPU hours to 3.3 seconds.
Canvas-to-Image introduces a unified framework that consolidates heterogeneous controls (subject references, bounding boxes, pose skeletons) into a single canvas interface for high-fidelity compositional image generation.
Diffusion-DRF uses a frozen VLM critic to provide free, rich, and differentiable feedback for stable video diffusion fine-tuning.
EasyV2V: A high-quality instruction-based video editing framework that enables intuitive video manipulation through natural language instructions.
Omni-Attribute can isolate a specific attribute, whether it is an abstract concept or not, from any image and merge those selected attributes from multiple images into a coherent generation.
We prevent shortcuts in adapter training by explicitly providing the shortcuts during training, forcing the model to learn more robust representations.
ComposeMe is a human-centric generative model that enables disentangled control over multiple visual attributes — such as identity, hair, and garment — across multiple subjects, while also supporting text-based control.
ThinkDiff enables multimodal in-context reasoning in diffusion models by aligning vision-language models to LLM decoders, transferring reasoning capabilities without requiring complex reasoning-based datasets.
Omni-ID is a novel facial representation tailored for generative tasks, encoding identity features from unstructured images into a fixed-size representation that captures diverse expressions and poses.
WonderLand is a video-latent based approach for single-image 3D reconstruction in large-scale scenes.
AC3D studies when and how you should condition camera signals into a video diffusion model for a better camera control and a higher video quality.
Magic123 proposes a hybrid score distillation algorithm and a coarse-to-fine image-to-3D pipeline that produces high-quality high-resolution 3D content from a single unposed image.
Pix4Point shows that image pretraining significantly improves point cloud understanding.
PointNeXt boosts the performance of PointNet++ to the state-of-the-art level with improved training and scaling strategies.
ASSANet makes PointNet++ faster and more accurate.
