# The Inner Workings of Claude and OpenAI's 'Super App' The hidden world of AI models and the impact of ChatGPT Work on the business world. - **Source:** [MIT Technology Review](https://www.technologyreview.com) - **Published:** 2026-07-10 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/24f89c1a-e233-4bbf-bbef-672a2a0310bb ## Claude's Hidden World Anthropic developed a tool called the Jacobian lens to understand the inner workings of large language models. This tool discovered a hidden area called J-space inside the Claude model. This area contains words the model works on but may not ultimately produce, offering significant insights into AI's thought processes. ## The Function of J-space J-space holds words Claude uses to formulate responses but may not ultimately produce. This is a crucial step in understanding the model's thought processes. If Claude were human, these words would reveal what's on its mind before it speaks. ## OpenAI's Super App OpenAI developed a new application called ChatGPT Work. This app combines chatbot, coding tool, and new models. ChatGPT Work is designed to do users' work both for them and with them. ## GPT 5.6 Models On the day ChatGPT Work was launched, OpenAI also introduced GPT 5.6 models. These models mark a new era in AI technology. Additionally, efforts to develop a fully automated researcher are ongoing. ## Teleoperated Surgery Humanoid robots performed teleoperated surgical operations on live animals. This is recorded as a world-first. The robots successfully removed gallbladders from pigs. ## The Future of AI AI technology is rapidly advancing and becoming more integrated into our daily lives. However, how this technology will be practically applied and its impacts remain topics of debate. These developments lay the foundation for future technological innovations. ## Sources covering this story - https://www.technologyreview.com/2026/07/10/1140316/the-download-anthropic-claude-hidden-space-openai-super-app/ — --- _Summary written by Brifing from the original reporting.
