Uber and OpenAI have expanded their partnership, with Uber giving its entire global workforce of about 30,000 people access to ChatGPT Work. The tool was first piloted with 1,000 employees earlier this year, and most early adopters were non-engineers. Uber says staff used it to analyse operational data, localise training materials and build dashboards. The company has not settled on exactly how employees will use it, and it did not disclose the cost of the rollout. Uber plans to track usage and use the results to guide its wider use of AI.
OpenAI has launched Locked Chats in ChatGPT, allowing users to protect sensitive conversations with a four-digit PIN, Face ID or Touch ID on supported devices. Locked chats move to a separate section and stay out of regular history, pinned chats and search results. They also have their own memory that does not feed into regular memory. The feature does not provide end-to-end encryption, change retention periods or remove information already remembered. Resetting a PIN permanently deletes all locked content. The rollout began on Tuesday and is not yet live for every user.
Replit chief executive Amjad Masad said the AI coding platform has stopped working with Anthropic and now favours OpenAI. He cited cost, performance and partnership as reasons. Users can still choose Anthropic's Claude models, but ChatGPT is now the default, which could sharply reduce Replit's spending with Anthropic. Insiders disputed that the partnership had ended, pointing to recent promotion of Anthropic products. Masad also said enterprise customers made up 15 per cent of revenue this year.

Amulya Vishwanath, a former NVIDIA product marketing leader, says robotics is in its early "Lego era", with core components such as actuators, robotic hands, software and safety standards still being developed. Her view contrasts with claims by General Intuition CEO Pim de Witte that a single general foundation model will soon make specialised robotics work redundant. In a TechCrunch Equity podcast episode, Vishwanath discussed where she is investing as founder and managing partner of Techable VC, which backs physical AI across robotics, materials science and life sciences.
Executives say voice AI has not yet reached its ChatGPT moment, despite heavy investment and frequent releases. PolyAI chief technology officer Shawn Wen said full-duplex models, which can speak while listening, have been developed, but reasoning must become faster for conversations to feel natural. Otter chief marketing officer Alex Gay said accurate speech recognition is vital, since transcription errors undermine follow-up actions and erode trust. Both executives stressed that voice tools should make clear to people that they are speaking with, or being recorded by, an AI.
