ORIGEN Zero-Shot 3D Orientation Grounding in Text-to-Image Generation

Inference-time scaling can work for flow models KAIST AI proposed 3 key ideas to make it possible: • SDE-based generation – Adding controlled randomness allows flow models to explore more outputs, like diffusion models do. • VP interpolant conversion – Guides the model from

Unconditional Priors Matter! The key to improving CFG-based "conditional" generation in diffusion models actually lies in the quality of their "unconditional" prior. Replace it with a better one to improve conditional generation! 🌐 unconditional-priors-matter.github.io

🔥 Grounding 3D Orientation in Text-to-Image 🔥 🎯 We present ORIGEN — the first zero-shot method for accurate 3D orientation grounding in text-to-image generation! 📄 Paper: arxiv.org/abs/2503.22194 🌐 Project: origen2025.github.io

🚀 Check out our inference-time scaling with FLUX. GPT-4o struggles to follow user prompts involving compositional logical relations. Our inference-time scaling enables efficient search to generate samples with precise alignment to the input text. 🔗 flow-inference-time-scaling.github.io

Introducing ORIGEN: the first orientation-grounding method for image generation with multiple open-vocabulary objects. It’s a novel zero-shot, reward-guided approach using Langevin dynamics, built on a one-step generative model like Flux-schnell. Project: origen2025.github.io

#ICLR2025 Come join our StochSync poster (#103) this morning! We introduce a method that combines the best parts of Score Distillation Sampling and Diffusion Synchronization to generate high-quality and consistent panoramas and mesh textures. stochsync.github.io

❗️Vision-Language Models (VLMs) struggle with even basic perspective changes! ✏️ In our new preprint, we aim to extend the spatial reasoning capabilities of VLMs to ⭐️arbitrary⭐️ perspectives. 📄Paper: arxiv.org/abs/2504.17207 🔗Project: apc-vlm.github.io 🧵[1/N]

I recently presented our work, “Inference-Time Guided Generation with Diffusion and Flow Models,” at HKUST (CVM 2025 keynote) and NTU (MMLab), covering three classes of guidance methods for diffusion models and their extensions to flow models. Slides: onedrive.live.com/?redeem=aHR0cH…

📈 Can pretrained flow models generate images from complex compositional prompts—including logical relations and quantities—without further fine-tuning? 🚀 We have released our code for inference-time scaling for flow models: github.com/KAIST-Visual-A…

🧐 Can we define a better initial prior for Sequential Monte Carlo in reward alignment? That's exactly what Ψ-Sampler 🔱 does. Check out the paper for details: 📌 arxiv.org/abs/2506.01320
