OpenAI took its Dev Day roadshow to London this week to sell developers on Dots, its new always-on AI assistant first announced at its annual developer event in San Francisco a month ago and pitched as its flagship agentic offering. Unlike tools such as Codex, which wait for user instructions, Dots are meant to be proactive—learning a user’s goals, watching their inbox and work tools, and starting tasks before they ask. Dots aren’t available in Europe yet, but OpenAI said it is working with European regulators to change that. OpenAI is positioning Dots against competitors including Meta’s Muse, Elon Musk’s xAI Grok Bot, and Anthropic’s Duet by betting on high-end, high-spend users first, rolling Dots out to enterprises and its most expensive Pro subscribers in the U.S. Romain Huet, OpenAI’s head of developer experience, said the company wanted to “nail the enterprise and pro use case first.” The strategy reflects how expensive these agents are to run: Adam Fry, who runs ChatGPT’s consumer business, said Dots are “on the compute-heavy side,” and OpenAI is routing some Dot tasks to Terra, a smaller GPT-6.1 model, instead of the larger GPT-6 Astra. Huet said Terra can perform better than Astra in some areas, such as computer use and writing, at “a tenth of the price.”
