Engineering & Research
Large Animatable Human Reconstruction Model for Single Image to 3D in Seconds (GitHub Repo)
Code release for a method that takes a single image as input and creates a fully animatable 3D avatar. It is permissively licensed and seems to work quite well.
Tokenize an Image as a Set (GitHub Repo)
"Tokenize Image as a Set" is a new framework for image generation that uses set-based tokenization and a novel discrete diffusion method. The approach represents images as unordered token sets, enabling a unique and invertible generative modeling process.
Latent Multi-Hop Reasoning (GitHub Repo)
This research investigates whether Large Language Models (LLMs) perform multi-hop reasoning – a process of connecting multiple pieces of knowledge – when presented with complex prompts. The study found evidence of this latent reasoning process, particularly in the initial step, but utilization of the connected knowledge varied and showed a scaling trend with model size, suggesting both challenges and opportunities for future LLM development.
People are using Google's new AI model to remove watermarks from images (2 minute read)
Google's new Gemini 2.0 Flash AI model can remove watermarks from images, raising copyright concerns. The tool, available in Google's AI Studio, is experimental and not suited for production use, yet shows advanced capabilities in watermark removal. Google states that using its generative AI tools for copyright infringement violates its terms of service.
Apple's AI strategy plagued by delays, Siri upgrade remains in limbo (3 minute read)
Apple is facing delays and challenges with its AI features for Siri, initially planned for iOS 18.5 but now possibly pushed to 2026. Despite showcasing features at WWDC, internal assessments reveal the technology isn't ready for public release yet. Apple remains optimistic in enhancing Siri, aiming for significant improvements by 2027 with a new infrastructure to stay competitive.
OpenAI exec leaves to found materials science startup (1 minute read)
