OpenAI released new AI tools on September 29, 2026, saying it introduced agents that can take on ongoing responsibilities and new ways for people and AI to work together. It is the company's first major update in the model-release category since its prior milestone in 2025.
OpenAI reported 1.2B weekly users, measured on its platform, that compares with the earlier figure of 1.1B. That represents a significant increase in its user base.
The new tools are built on Codex & the API and target improved collaboration between humans and AI, with features like plugins and agents. Availability begins with a phased rollout, initially for developers and enterprise users.
"We believe AI can help bring about a new renaissance of creativity and discovery," said Sam Altman, CEO of OpenAI. "It should give people more time for what matters to them, more freedom to pursue their ideas, and the ability to do things they didn’t think were possible."
The announcement follows DevDay 2026, where OpenAI highlighted its commitment to an open ecosystem. OpenAI itself frames the significance as a step toward creating a shared surface where humans and agents can collaborate.
OpenAI did not say when the full rollout will occur, and raised the open question of how to balance user privacy with enhanced collaboration. The source says the company will continue to develop these tools in the coming months.
