Anthropic has unveiled new findings on its large language model, Claude, utilizing a tool called the Jacobian lens (J-lens) to explore a hidden area known as J-space. This space contains words related to the responses the model generates, providing insight into its processing before delivering output. In related news, OpenAI has launched its long-anticipated 'super app,' ChatGPT Work, which integrates its chatbot, coding tools, and new models to enhance productivity. On the tech front, humanoid robots have successfully performed teleoperated surgeries on living animals, and SK Hynix has executed the largest US listing by a foreign company, raising $26.5 billion amid rising demand for AI data centers.
