OpenAI Just Killed Claude Code

OpenAI's New Codex Plan: A Game Changer?

Overview of the New Codex Plan

  • OpenAI has introduced a $100/month Codex plan, offering five times the usage of the previous $20/month plan and access to features from the former $200/month plan, including Chat GPT Pro.
  • The speaker has primarily used Claude Code for teaching but has shifted to using the Codex desktop app for most work over the past two months.

Budget Considerations for AI Subscriptions

  • Many students find the $200/month plan too expensive while the $20/month option lacks sufficient usage; thus, the new $100/month plan is seen as a viable solution.
  • The speaker now recommends that anyone with a single AI subscription budget should opt for a Chat GPT subscription they can afford—$20, $100, or $200.

Reasons to Prefer Codex Over Claude Code

1. Model Quality

  • Codex utilizes Chat GPT 5.4 as its default model, which outperforms Claude Code’s Opus 4.6 in various tasks.
  • For technical machine learning work and data-related tasks, Codex is noted to be more effective despite being slightly slower than Opus 4.6.

2. Developer Insights

  • Pete Steinberger, creator of Open Claw (now part of OpenAI), highlights that Opus tends to be "sloppy" compared to Codex in handling complex coding scenarios.
  • Yacine, an engineer turned hardware startup founder, expresses strong support for Codex based on his experiences with it outperforming other models.

3. Performance Features

  • The speaker notes improvements in speed within Codex and mentions an optional fast mode that doubles processing speed at a higher token cost.

4. Areas Where Claude Code Excels

  • Despite its advantages, Claude Code still performs better in web design and writing tasks such as academic papers and tutorials; however, this difference is not significant enough to recommend continued use over Codex.

User Interface Advantages of Codex

Desktop Application Benefits

  • The interface of the Codex desktop app is described as superior for agentic coding compared to competitors.
  • Users can easily manage multiple sessions and integrate terminal functionality directly within their projects.

Collaboration Features

  • Integration with Git allows users to track changes made by Codex during project development effectively.

Work Tree Functionality

  • The ability to create parallel copies of projects (work trees) enables simultaneous work on different aspects without conflicts—a feature highlighted as particularly beneficial in project management.

Codex vs. Claude Code: A Comparative Analysis

Overview of Codex Desktop Application Features

  • The Codex desktop application features a blue bubble notification system that helps users track open threads and necessary responses, enhancing workflow efficiency.
  • Users can easily manage their skills by project within the app, allowing for quick enabling or disabling of specific functionalities as needed.
  • A recommendation is made to adopt the Codex desktop application promptly if already subscribed, highlighting its advantages over competitors.

Performance Comparison with Claude Code

  • Developers have noted deficiencies in Opus 4.6 compared to GPT 5.4, particularly in debugging capabilities where GPT 5.4 performs better.
  • Pete Steinberger from OpenAI praises the Codex desktop app's performance, stating it surpasses command-line interface (CLI) tools in usability.
  • User feedback on Claude Code indicates significant UI issues leading to frustration and inefficiency, contrasting with positive experiences reported with Codex.

Subscription Value and Usage Limits

  • The $20/month subscription for Codex reportedly offers comparable usage benefits to the $100/month plan for Claude Code, making it a more cost-effective option.
  • Both services impose daily and weekly usage limits; however, users on higher-tier plans often hit these limits quickly, hindering productivity.

Learning Curve and Productivity Impact

  • Frequent interruptions due to usage limits can impede learning opportunities; continuous access allows users to develop proficiency more effectively.
  • Anecdotal evidence suggests that many users experience rapid limit exhaustion on higher-tier plans like Claude Code’s $100/month option.

Community Feedback and Recommendations

  • Discussions in online forums reveal widespread dissatisfaction with Claude Code's limitations; many recommend switching to alternatives like Codex for better performance.
  • Users report hitting rate limits rapidly even under heavy workloads while using Claude Max at $100/month, indicating systemic issues within the service.

Conclusion on Tool Effectiveness

  • Overall user sentiment favors Codex over Claude Code due to fewer restrictions and superior functionality during extended work sessions.
  • Prominent developers echo similar frustrations regarding usage caps affecting their ability to perform complex tasks efficiently across both platforms.

ChatGPT Pro vs. Claude Code: Which AI Subscription is Better?

Overview of ChatGPT Pro Features

  • The Pro tier provides access to all features, including the exclusive Pro model and unlimited modes (instant and thinking).
  • The Pro model allows for extensive computational resources, making it superior for tackling complex problems compared to alternatives like Anthropic's offerings.
  • Users can leverage ChatGPT Pro for detailed technical insights and error detection that surpasses other tools in accuracy.

Integration with Codex and Oracle

  • Codex integration with ChatGPT Pro is facilitated through a tool called Oracle, which bundles codebase context for enhanced responses.
  • This integration is particularly beneficial for academic work where correctness is crucial; users can find detailed solutions efficiently.

Usage Limits and Advantages of Codex

  • OpenAI has increased usage limits for Codex subscribers, offering up to 10x usage compared to previous limits as a promotional effort until May 31st.
  • In contrast, Anthropic's Claude Code has tightened its usage limits, leading to frustrations among users due to lack of resets on limits during peak times.

Comparison of Subscription Benefits

  • Codex frequently resets rate limits, providing a sense of almost infinite usage compared to Claude Code’s stricter limitations.
  • Anthropic has reduced session limits during peak hours (5 AM - 11 AM PT), affecting user experience negatively.

Recommendations Based on Experience

  • The speaker recommends using Codex primarily (80% of the time), while still maintaining a Claude Code subscription for specific tasks (20%).
  • An extensive course on Codex is being developed due to its perceived value; the speaker also offers tutorials and community engagement opportunities through their platform.

I think this update kills Claude Code as the default recommendation for anyone with room for one AI subscription. I teach Claude Code, I just put out a full 3-hour course on it — and yet for the last two months I've been using the Codex desktop app as my daily driver. In this video I walk through the 5 reasons the new $100 tier changes everything: model quality (GPT-5.4 vs Opus 4.6), the Codex desktop app interface, usage-per-dollar at the $100 tier, the ChatGPT Pro bundle (and how to pair it with Codex via Oracle), and the opposite trajectories the two companies are on — Anthropic tightening caps while OpenAI keeps resetting and doubling them.
