OpenAI opens ChatGPT to third-party agents at DevDay

OpenAI’s DevDay announcements push ChatGPT and its APIs deeper into enterprise workflows by enabling third-party agents, new developer tooling, faster and cheaper models, and stronger data-protection options. For CIOs, the strategic signal is clear: AI is moving from isolated copilots to an extensible operating surface for automated work, which could improve productivity and speed but also raises governance, security, integration, and vendor-dependence considerations for IT organizations.
