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 …
Summary Google and Deepmind are working together to develop a GPT-4 competitor called “Gemini”. The Information reports that the Google Brain AI team is working with Deepmind on an alternative to OpenAI’s GPT-4. Work on the Gemini project is said to have begun in recent weeks after Google’s Bard failed to keep up with ChatGPT. …
Summary Stanford’s Alpaca was just the beginning: In recent weeks, several AI models have been unveiled using training data generated by ChatGPT. In mid-March, Stanford researchers unveiled the Alpaca language model, a variant of Meta’s LLaMA 7B that was fine-tuned with AI-generated data. The team trained the LLaMA model with 52,000 example statements generated by …
Summary After Alpaca comes Vicuna, an open-source chatbot that, according to its developers, is even closer to ChatGPT’s performance. Vicuna follows the “Alpaca formula” and uses ChatGPT’s output to fine-tune a large language model from Metas LLaMA family. The team behind Vicuna includes researchers from UC Berkeley, CMU, Stanford, and UC San Diego. While Alpaca …
GPT-4 likes this chatbot almost as much as ChatGPT Read More »
Summary PAC-NeRF demonstrates how NeRFs can learn the geometric structure and physical properties of objects from video. Neural radiance fields (NeRFs) are a powerful AI-based rendering technology that can be used for video production, 3D reconstruction, and other tasks. They learn to represent and render the geometric structure and lighting of scenes and objects from …

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 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 …
