LakonLab
Research hub for flow-based generative models and 3D generation, with top-venue publications and open source demos.
Essential bookmark for researchers tracking flow-based and diffusion models. The breadth of high-impact publications is impressive, but don't expect a usable product—it's a project listing with links to code and demos. Go straight to the GitHub repos for hands-on work. For a production-ready alternative, consider commercial APIs like Stable Diffusion or Midjourney, which offer hosted interfaces.

About LakonLab
LakonLab is the personal research page of Hansheng Chen, cataloging over a decade of peer-reviewed work on generative AI across image, video, and 3D modalities. The site serves as a structured index of projects—each linking to arXiv papers, GitHub repositories, and live demos—making it a practical resource for researchers and advanced practitioners who want to reproduce or build on state-of-the-art methods. It is not a product or API; it's an academic portfolio designed for exploration. The page is anchored by several high-impact flow-based generative models. AsymFlow (arXiv 2026) introduces a rank-asymmetric flow parameterization that achieves 1.57 FID on ImageNet, beats its latent base after latent-to-pixel finetuning, and ranks #1 on the HPSv3 text-to-image benchmark. pi-Flow (ICLR 2026) distills pre-trained flow models into a policy-based model using imitation learning, delivering state-of-the-art 4-step text-to-image generation with teacher-aligned quality. GMFlow (ICML 2025) generalizes diffusion/flow matching by predicting Gaussian mixture denoising distributions, adding novel GM-SDE/ODE solvers and probabilistic guidance for few-step sampling. Beyond image generation, LakonLab covers substantial 3D work: 3D-Adapter for geometry-consistent multi-view diffusion, MVEdit for training-free 3D editing via off-the-shelf Stable Diffusion, and GRM for large Gaussian reconstruction in ~0.1s. Recent additions include Img2CAD (SIGGRAPH Asia 2025), which reverse-engineers editable CAD models from single images using VLM assistance, and a zero-shot inversion-free method for video editing from flow-based I2V models (arXiv 2025). Earlier projects like Zero123++ and One-2-3-45++ remain foundational for image-to-3D tasks. What distinguishes LakonLab is its track record: publications at ICML, ICLR, ECCV, SIGGRAPH Asia, CVPR, and ICCV, including a CVPR Best Student Paper for EPro-PnP. The research balances theoretical novelty with practical scalability, but the page is strictly an index—you'll need to follow links to GitHub and demos for hands-on work.
Behind the Verdict
LakonLab is a goldmine for anyone serious about generative models. The research spans image, video, and 3D, with a clear focus on flow-based methods—a cutting-edge area. AsymFlow's 1.57 FID on ImageNet is a state-of-the-art result in pixel-space generation, and pi-Flow's 4-step generation is a practical advance for speed-sensitive applications. GMFlow's theoretical contributions to few-step sampling are well-regarded in the community. Strengths: Each project links to arXiv, GitHub, and often a live demo, so you can quickly evaluate and reproduce results. The work is published at top venues (ICML, ICLR, ECCV, CVPR), signaling rigor. The 3D generation track is particularly strong, with methods like GRM achieving ~0.1s reconstruction—useful for real-time pipelines. Weaknesses: The page is a static index; there's no unified API or hosted service. You'll need to clone repos, manage dependencies, and have capable hardware to run demos. Documentation varies per project. Neither is there a community forum or support channel. Where it fits: Best for researchers, grad students, and engineers at AI labs who want to build on state-of-the-art methods. If you need a plug-and-play solution, look elsewhere—commercial APIs like Stable Diffusion or Midjourney offer hosted interfaces, but you lose the flexibility and transparency of open-source code. Where it doesn't: Non-technical users or those needing production SLAs will find no support. The lack of a unified interface makes it unsuitable for rapid prototyping without ML expertise.

Models Under the Hood
as of 2026-08-30
Limitations
- LakonLab is a research project page, not a product.
- There are no hosted APIs, customer support, or user-friendly interfaces.
- All models require technical expertise to use and are provided as open-source code.
- The page primarily serves as a directory; actual usage depends on third-party platforms (GitHub, Hugging Face demos).
