OpenAI released a major Codex update on April 16, 2026 under the banner "Codex for (almost) everything," transforming the app from an agentic coding tool into a general-purpose AI workspace that can control a Mac desktop, browse the web via an in-app browser, generate images with gpt-image-1.5, retain memory across sessions, schedule future autonomous tasks, and connect to 90+ external services including Jira, Microsoft 365, Notion, and Slack. Multiple agents can run in parallel on macOS without interrupting the user's own work; Windows support was not announced. The update arrived as OpenAI reported more than 3 million weekly active Codex developers—nearly double the count from early March—and intensifies competition with Anthropic's Claude Code.
