In San Francisco, still for now the center of the AI action, one can track these advances in the waves of new computer learning methods, chatbot features and podcast-propagated buzzwords. In February, OpenAI unveiled a tool called Deep Research that functions like a resourceful colleague, responding to in-depth queries by digging up facts on the web, synthesizing information and generating chart-filled reports. In another major development, both OpenAI and Anthropic—co-founded by Chief Executive Officer Dario Amodei and a breakaway group of former OpenAI engineers—developed tools that let users control whether a chatbot engages in “reasoning”: They can direct it to deliberate over a query for an extended period to arrive at more accurate or thorough answers.
