Summary People take photos for many reasons, one of which is to capture memories. The next generation of keepsake photos may be NeRFs, which get a quality upgrade at high speed with Zip-NeRF. Google researchers demonstrate Zip-NeRF, a NeRF model that combines the advantages of grid-based techniques and the Mipmap-based mip-NeRF 360. Grid-based NeRF methods, …
Zip-NeRF is another step towards a digital time machine Read More »
Newsletter In recent years, the potential progress of large language models has been measured primarily by the number of parameters. Sam Altman, CEO of OpenAI, believes that this practice is no longer useful. Altman compares the race to increase the number of parameters in large language models to the race to increase the clock speed …

Summary All generative AI models for images currently use diffusion models. OpenAI presents an alternative that is significantly faster and could power new models like DALL-E 3. DALL-E 2, Stable Diffusion, or Midjourney use diffusion models that gradually synthesize an image from noise during image generation. The same iterative process is used in audio or …
Here’s how OpenAI’s DALL-E 3 could leapfrog the competition Read More »
Summary A new beta version of Stable Diffusion delivers much more aesthetic and photorealistic results than the previous version. Will this make commercial offerings obsolete? While Stable Diffusion is the most developed open-source image model, it can’t always match the quality and especially the accessibility of commercial competitors like Midjourney. Its strength so far is …
Summary Characters in video games could soon feel even more realistic. But these AI sims could also be helpful outside of gaming. In a new paper, researchers from Google and Stanford University simulate human behavior using large-scale language models. The paper, titled “Generative Agents: Interactive Simulacra of Human Behavior” relies on ChatGPT and offers more …

Summary Neural Radiance Fields (NeRFs) are a promising graphics technology that can transform the real world into 3D relatively quickly and with high quality. LERF (Language Embedded Radiance Fields) integrates the capabilities of large language models into NeRFs. This enables accurate 3D object recognition without additional training. UC Berkeley researchers present LERF, which volumetrically integrates …
Summary OpenAI CEO Sam Altman announced that scientists will continue to have access to the model after a wave of criticism over the Codex shutdown. “We didn’t realize how much people liked this model; we will continue to support it for researchers!” he wrote on Twitter. Only a few days after a first notice, OpenAI …

Summary Microsoft researchers see a spark of general AI in an early version of GPT-4. “We believe that GPT-4’s intelligence signals a true paradigm shift in the field of computer science and beyond,” says the paper released by Microsoft. GPT-4 shows a spark of general artificial intelligence (AGI), they say, but is only the first …
