Excited to share our #ICCV2025 work Reusing Computation in Text-to-Image Diffusion for Efficient Generation of Image Sets!

Our method generates large sets of images using significantly less compute than standard diffusion.

This work was led by Sining Lu and Guan Chen, in collaboration with Nam Anh Dinh, Itai Lang, Ari Holtzman, and me.

We’re still actively developing LL3M, and we’d love to hear your thoughts! 7/

Another cool thing about LL3M: the Blender code it writes is actually readable. Clear structure, detailed comments, intuitive variable names. Easy to tweak a single parameter (e.g. key width) or even change the algorithmic logic (e.g. the keyboard pattern). 6/

LL3M generates 3D assets in 3 phases with specialized agents:
1️⃣ Initial Creation → break prompt into subtasks, retrieve relevant code snippets (BlenderRAG)
2️⃣ Auto-refine → critic spots issues, verification checks fixes
3️⃣ User-guided → iterative edits via user feedback
5/

LL3M can create a wide range of shapes, without requiring specialized 3D datasets or fine-tuning. Every asset created is represented under the hood as editable Blender code. 4/

Even non-experts can jump right in and easily edit 3D shapes. Blender code created by LL3M generates a node graph that is packed with tunable parameters, enabling users to tweak colors, textures, patterns, lengths, heights, and more. 3/

What we ❤️ about LL3M: You're in the loop! If you want to make a tweak, LL3M can be your collaborative 3D design partner. And there's no need to regenerate the entire model each time - target a specific part, provide follow-up prompts, and the rest stays intact. 2/

We’ve been building something we’re 𝑟𝑒𝑎𝑙𝑙𝑦 excited about – LL3M: LLM-powered agents that turn text into editable 3D assets. LL3M models shapes as interpretable Blender code, making geometry, appearance, and style easy to modify. 🔗 threedle.github.io/ll3m 1/

Our work “Geometry in Style” will be presented at #CVPR2025 on Sunday at 4pm in ExHall D, poster 219. Drop by and say hi!

Our technique is capable of performing expressive text-driven deformations that preserve the input shape identity.

Congrats Brian and team on the best paper honorable mention at #3dv2025 🥳🎉
Brian (hywkim-brian.github.io/site/) is going to start his PhD next year at Columbia with @silviasellan.bsky.social Make sure to watch out for their awesome works 📈📈📈

Tweet advertising that Rana Hanocka at UChicago CS is recruiting PhD students.

My colleague Rana Hanocka does exciting work on the frontier for 3D graphics and AI/ML, and she’s recruiting PhD students this cycle!
