The OpenAI power struggle that captivated the tech world after co-founder Sam Altman was fired has finally reached its end — at least for the time being. But what to make of it? It feels almost as though some eulogizing is called for — like OpenAI died and a new, but not necessarily improved, startup
MIT CSAIL researchers innovate with synthetic imagery to train AI, paving the way for more efficient and bias-reduced machine learning.
By blending 2D images with foundation models to build 3D feature fields, a new MIT method helps robots understand and manipulate nearby objects with open-ended language prompts.
The Orca-2-13B, part of Microsoft's Orca 2 series, comes in 7B and 13B parameter versions, fine-tuned from the LLAMA 2 base models. This model excels in reasoning, text summarization, math problem-solving and comprehension tasks, building upon the original 13B Orca model. It imitates the reasoning process of advanced AI systems step by step, aiming to enhance smaller models’ capabilities in complex tasks.
One AI startup’s undoing is another’s opportunity. Case in point: today, AI21 Labs, a company developing generative AI products along the lines of OpenAI’s GPT-4 and ChatGPT, closed a $53 million extension to its previously-announced Series C funding round. The new tranche, which had participation from new investors Intel Capital and Comcast Ventures, brings AI21’s
