Before OpenAI’s developer conference even began, users already received a “shrinkage notice”: the $200-per-month Pro plan would reopen to new users, but usage limits would be cut in half.

The price stayed the same; the benefits did not. So what does OpenAI still have to persuade people to keep paying? That is the question this DevDay needed to answer.

Just now, OpenAI CEO Sam Altman announced a string of updates in one breath: Dots, ChatGPT Space, GPT-6.1 Sol, UltraFast, Pro 500, Decisions API, Agents API, cloud Codex, and the OpenAI Marketplace.

The event looked packed with new products, but the through-line was tight. OpenAI is connecting models, agents, collaboration spaces, and commercial distribution so that ChatGPT can evolve from a tool that generates answers into a work platform that understands context, calls software, and takes on long-running tasks.

This launch was less about defining brand-new categories than about a full-scale peer comparison: forms others have already validated, OpenAI wants to rebuild in a platform way.
