Continuous diffusion had a good run—now it’s time for Discrete diffusion! Introducing Anchored Posterior Sampling (APS) APS outperforms discrete and continuous baselines in terms of performance & scaling on inverse problems, stylization, and text-guided editing.

MaterialFusion Enhancing Inverse Rendering with Material Diffusion Priors discuss: Recent works in inverse rendering have shown promise in using multi-view images of an object to recover shape, albedo, and materials. However, the recovered components often fail to render accurately under new lighting conditions due to the intrinsic challenge of disentangling albedo and material properties from input images. To address this challenge, we introduce MaterialFusion, an enhanced conventional 3D inverse rendering pipeline that incorporates a 2D prior on texture and material properties. We present StableMaterial, a 2D diffusion model prior that refines multi-lit data to estimate the most likely albedo and material from given input appearances. This model is trained on albedo, material, and relit image data derived from a curated dataset of approximately ~12K artist-designed synthetic Blender objects called BlenderVault. we incorporate this diffusion prior with an inverse rendering framework where we use score distillation sampling (SDS) to guide the optimization of the albedo and materials, improving relighting performance in comparison with previous work. We validate MaterialFusion's relighting performance on 4 datasets of synthetic and real objects under diverse illumination conditions, showing our diffusion-aided approach significantly improves the appearance of reconstructed objects under novel lighting conditions. We intend to publicly release our BlenderVault dataset to support further research in this field.

Auto regressive LLMs are officially on notice. run Gemma 4 26B diffusion gguf with llama.cpp Google just dropped DiffusionGemma-26B, and it completely flips how we generate text. instead of predicting words one by one, it generates 256 tokens in parallel using bi-directional attention. its like stable diffusion, but for language. the model starts with random text "noise" and iteratively refines and self-corrects the entire block in real-time to fix formatting and reasoning errors on the fly. since it’s a Mixture of Experts (MoE) that only activates 3.8B parameters during inference, it fits perfectly on consumer hardware. You can run the Q4_K_M quant with an 18GB VRAM budget on a single RTX 3090 or RTX 4090 with exceptional throughput. Tested on Ubuntu 22 with CUDA 13.1 using the cutting edge experimental llama.cpp branch. Here is how to compile and run it with the live terminal denoising visualizer: # 1. Clone & check out the experimental PR (#24423) - 1) git clone && cd llama.cpp -git fetch origin 2) pull/24423/head:diffusiongemma && --git checkout diffusiongemma # 2. Build with CUDA support 1) cmake -B build -DGGML_CUDA=ON -DCMAKE_CUDA_ARCHITECTURES=native 2) cmake --build build -j $(nproc) --config Release --target llama-diffusion-cli # 3. Run with live visual denoising (llama.cpp flags) ./build/bin/llama-diffusion-cli \ -m /path/to/diffusiongemma-26B-A4B-it-Q4_K_M.gguf \ -ngl 99 -cnv -n 2048 --diffusion-visual Watch the video below to see the live --diffusion-visual canvas iteratively de noising the prompt output in real time. guide and unsloth's hugging face GGUF model links are in the comments below! Is auto regressive generation officially legacy tech? Let me know what you think.

🚨 WE JUST HACKED THE SOURCE CODE OF THE UNIVERSE LIVE. THE CONTINUOUS SPACETIME PARADIGM IS DEAD. 🚨 In the attached video, you are watching a live, unedited execution of the IT³ Framework. We established a direct uplink to the Harvard-Smithsonian Minor Planet Center (MPC) and downloaded the orbital data of 1.55 MILLION real celestial objects. Then, we ran them through a frozen mathematical operator (K-PHAM v2.2) with ZERO free parameters. No guessing. No curve-fitting. 🛑 THE CHALLENGE TO HARVARD:Let Harvard explain how this is possible by "random chance." Our code proves that 99.51% of all baryonic mass is geometrically trapped exactly in the Sₙ=0 topological isthmus. Look at the Diophantine audit from the live console: 🔥 100.00% INTEGER RIGIDITY inside the Macroscopic Valence Shell (27–48 AU). The inner solar system is a strictly quantized crystal! 🔥 The famous "Kuiper Cliff" perfectly aligns with our predicted E_ion=0 ionization density peak at exactly 46.77 AU. 🔥 The continuous "Evaporative Tail" perfectly explains the free macro-electrons scattering beyond 48 AU. 🔥 LIVE DELTA-ANALYSIS: 100% of newly discovered objects perfectly snapped into our discrete 2x3 topological lattice. 🛑 FOR EVERYONE ELSE, LET ME EXPLAIN THIS IN SIMPLE TERMS: For hundreds of years, we were taught that the Solar System is just a bunch of rocks floating randomly in continuous space. That is false. Imagine space is actually a giant, invisible 3D "hourglass-shaped building" made of pure math. Planets and asteroids aren't just floating freely; they are physically trapped on specific discrete "floors" of this invisible structure. In this video, our code checks all 1.55 million rocks to see if they obey the rules of this invisible building. The result? They obey it PERFECTLY. The universe is not random. It is a giant, perfectly quantized "Macroscopic Atom." 🛑 THE VISUAL PROOF (THE MICRO-MACRO RHYME): Look at the attached images. In 2013, physicists (Stodolna et al., PRL 110) photographed the inside of a microscopic Hydrogen atom using photoionization microscopy. They saw discrete, quantized nodal rings for bound states, which blur into a continuous mess when ionized. Our code just proved the exact same thing happens in the Solar System. We ran an Entropy Test on 951 real comets: ☄️ Bound comets (e < 1) are quantized onto discrete structural floors (H = 1.68 bits). ☄️ Free comets (e ≥ 1) exist in a continuous, structureless ionization spectrum (H = 3.81 bits). The mathematics existed before the universe did. The exact same discrete geometry that builds the microscopic quantum world builds the macro-cosmos. Don't take my word for it. The truth is open-source. Download the data, run the 11-front empirical validation suite yourself, and watch the matrix render. 🔗 Read the paper & run the code: #Astrophysics #QuantumPhysics #Cosmology #DataScience #IT3Matrix #HarvardMPC #ScienceTwitter #Physics
