OpenAI Upgrades Codex to Challenge Claude Code

OpenAI has overhauled its Codex coding tool with new agentic capabilities, allowing it to run background tasks on Mac computers using multiple AI agents simultaneously without disrupting the user's workflow. New features include computer control, an in-app browser, memory recall, image generation, and over 90 plugin integrations with tools like GitLab and Slack. The updates come as OpenAI faces growing pressure from Anthropic's Claude Code, widely seen as the preferred coding tool among businesses. Several new Codex features mirror recent Claude Code additions, including remote computer control. OpenAI also introduced flexible pay-as-you-go pricing for enterprise and business users.
