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 Using a game manual, an AI learned an old Atari game several thousand times faster than with older methods. This approach could be useful in other areas as well. In March 2020, DeepMind scientists unveiled Agent57, the first deep reinforcement learning (RL)-trained model to outperform humans in all 57 Atari 2600 games. For the …
Summary Is OpenChatKit the Stable Diffusion of chat models? Not quite yet, but it probably won’t be long. The open-source community Together has released the first open-source alternative to ChatGPT, OpenChatKit. The chatbot is based on EleutherAI’s 20 billion parameter language model GPT-NeoX and has been tuned with 43 million instructions for chat use. In …

Summary Researchers train a language model from Meta with text generated by OpenAI’s GPT-3.5 for less than $600 – and achieve similar performance. Training large language models is expensive, and powerful models remain the monopoly of large technology companies – right? Perhaps not. Researchers at Stanford used 52,000 instruction-following demonstrations generated by OpenAI’s GPT-3.5 (text-davinci-003) …

Summary Med-PaLM is Google’s variant of the PaLM language model optimized for medical questions. The latest version is designed to answer medical questions reliably at an expert level. Last December, Google unveiled Med-PaLM, a version of Google’s giant PaLM (Pathways Language Model) language model optimized for answering medical questions. Med-PaLM was developed using a special …

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 …
OpenAI kills its Codex code model, recommends GPT3.5 instead Read More »
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 …
