Generative AI

Simulating complex physical systems through traditional numerical methods is slow and expensive, and simulations based on machine learning are usually specialized for a specific type of system, such as water in a pipe or atmosphere surrounding a planet.

Google added a music generator to Gemini and YouTube, putting a model that produces synthetic songs in front of hundreds of millions of users.

OpenAI plans to shut down its video generator Sora in a sudden retreat from the video market.

xAI launched a video generator that topped an independent quality ranking at a fraction of competitors’ prices.

Downloads of mobile AI apps and resulting revenue are surging.

Google launched a cheaper, faster successor to its flagship image generator, delivering greater interactivity at roughly half the price.

Makers of software that runs large companies saw their share prices plunge as investors worried that AI systems could undermine their businesses. This week, their stocks rebounded somewhat as Anthropic partnered with some of the same companies.

Image generators often mangle text. An open-weights model outperforms open and proprietary competitors in text rendering.

Current methods that produce 3D scenes from text or images are slow and produce inconsistent results. Researchers introduced a technique that generates detailed, coherent 3D scenes seconds.

AI has a new revenue stream, and it looks a lot like old web banner ads.

A little more than three years ago, OpenAI released ChatGPT, and education changed forever. For students, the ability to generate fluent, credible text on demand in seconds is an incredible new tool.

Disney, the entertainment conglomerate that owns Marvel, Pixar, Lucasfilm and its own animated classics from 101 Dalmatians to Zootopia, licensed OpenAI to use its characters in generated videos.

Runway’s GWM-1 family of video-generation models respond to user input in real time while producing scenes that remain consistent regardless of the camera’s position.

Models that generate 3D spaces typically generate them as users move through them without generating a persistent world to be explored later. A new model produces 3D worlds that can be exported and modified.

Meta’s Segment Anything Model (SAM) image-segmentation model has evolved into an open-weights suite for generating 3D objects. SAM 3 segments images, SAM 3D turns the segments into 3D objects, and SAM 3D Body produces 3D objects of any people among the segments. You can experiment with all three.
