OpenAI Revamps Codex to Challenge Anthropic's Claude Code
OpenAI faces competition from Anthropic in the market for AI coding tools. Businesses favor Anthropic's Claude Code, as reports noted last week. OpenAI responded with major updates to its Codex tool.
The company revealed these changes on Thursday. Codex now runs in the background on a user's computer. It opens applications, moves the cursor, clicks, and types to perform tasks.
Background Agent Capabilities
Codex deploys multiple agents that operate on a Mac in parallel. They work without disrupting the user's activities in other apps, according to OpenAI's blog post. Users can continue their main projects while agents handle support tasks. OpenAI cites examples like refining frontend modifications, testing applications, or using apps without APIs.
These agent features make Codex more than a basic coding helper. It integrates into various company processes. Observers note similarities to Anthropic's tools. Last month, Anthropic enabled Claude and Cowork to control a user's Mac and desktop remotely when away from the keyboard.
New Tools and Integrations
Codex includes an in-app browser. Users send commands to the agent, which executes them in specific web apps. OpenAI highlights benefits for frontend and game development. Plans call for expansion so Codex fully controls browsers beyond localhost web apps.
A preview feature named "memory" lets Codex remember past sessions. It creates context on a user's work habits. The tool also generates images for product ideas, slide graphics, mockups, placeholder visuals, and business materials.

OpenAI added 111 plugin integrations, including CodeRabbit and Gitlab Issues. These let Codex manage tasks in those services. Plugins support routine organization, such as reviewing Slack channels and Google Calendar to produce daily to-do lists.
Pricing and Company Context
A pay-as-you-go pricing option launched for ChatGPT enterprise and business users. This provides more billing flexibility.
OpenAI once led AI development unchallenged. Recent months brought tougher rivalry with Anthropic, especially in enterprise features. The firm stepped back from consumer products like its social video app Sora 2. It also faced issues, including lawsuits claiming ChatGPT harmed some users' mental health.
OpenAI, founded in 2015 by Sam Altman and others, gained fame with ChatGPT's 2022 release, which popularized generative AI. Anthropic, started in 2021 by former OpenAI executives, focuses on safe AI systems and released Claude models as alternatives to GPT series. Both companies target developers and businesses with coding assistants. Codex originated from OpenAI's early code generation work, powering tools like GitHub Copilot. These updates position Codex to regain ground in agent-based coding, where desktop interaction adds practical value for teams.
The enhancements reflect a push toward autonomous agents that assist without constant oversight. Multiple agents running parallel tasks suit complex workflows. Background operation keeps productivity high. Plugin support connects Codex to daily tools, reducing manual steps.
Image generation fills gaps in design tasks during coding. Memory improves personalization over time. Browser control aids web-focused projects. Pay-as-you-go appeals to variable usage patterns in enterprises.
Competition drives innovation. Anthropic's lead prompted OpenAI's response. Both firms vie for corporate adoption, where reliable, powerful tools win contracts.
