DevDay

At DevDay, OpenAI announced a broad expansion of ChatGPT beyond chat: an open plugin platform, shared team workspaces called Space, native Slack and Microsoft Teams integration, workflow automation via MCP Events, and a new enterprise marketplace with 32 launch partners including Adobe, Figma, and Salesforce.

OpenAI is teasing 20+ announcements for its DevDay 2026 event, streaming live at 10am PT/1pm ET on September 29. Expectations center on a consumer-facing AI agent to counter xAI's Grok Bot and Meta's Muse.
