Elon Musk’s xAI has secured $6 billion in Series B funding. While the company says the funds will be “used to take xAI’s first products to market, build advanced infrastructure, and accelerate the research and development,” some outlets are reporting a significant portion is earmarked to build an AI supercomputer to power the next generation of its foundation model Grok. The company publicly released the open-source Grok-1 as a chatbot on X social in November, and recently debuted Grok-1.5 and 1.5V iterations with long-context capability and image understanding.

Maven is a new social network launched by OpenAI and Twitter alums designed to remove the pressure to amass followers and reinfuse a sense of serendipitous exploration, emphasized in its tagline: “Follow interests, not influencers.” Abandoning what it calls the “popularity-contest style” of most platforms, Maven doesn’t include likes, and lets people follow “interests” instead of other accounts. Its founders built Maven’s algorithm by drawing on the principles of open-ended systems. Its goals include increasing the probability of serendipity while addressing users’ curiosity, thus upping the odds of “meeting people with complementary interests.” Read more

Meta Platforms has unveiled its first natively multimodal model, Chameleon, which observers say can make it competitive with frontier model firms. Although Chameleon is not yet released, Meta says internal research indicates it outperforms the company’s own Llama 2 in text-only tasks and “matches or exceeds the performance of much larger models” including Google’s Gemini Pro and OpenAI’s GPT-4V in a mixed-modal generation evaluation “where either the prompt or outputs contain mixed sequences of both images and text.” In addition, Meta calls Chameleon’s image generation “non-trivial,” noting that’s “all in a single model.” Read more
