OpenAI's Codex(es) are starting to be really good

The video highlights the impressive advancements of OpenAI’s Codex ecosystem, especially with GPT-5, praising its seamless IDE-cloud integration and improved coding capabilities while noting frustrations with workflow interruptions and inconsistent UI elements. Despite some usability issues and stronger competition, the speaker remains cautiously optimistic about Codex’s potential and invites community feedback to help shape its future development.

The video discusses the evolving capabilities of OpenAI’s Codex ecosystem, particularly highlighting the impressive performance of GPT-5 integrated within these tools. The creator expresses a growing appreciation for the ecosystem, noting that while it may not surpass competitors like Claude, it shows significant promise. They share excitement about the quality of AI-generated code, showcasing examples like a highly polished Flappy Bird clone and a responsive Tetris game, both created with simple prompts. The speaker credits some of GPT-5’s improved coding results to effective prompting and system prompt enhancements unique to the Codex environment.

A standout feature praised in the video is the seamless integration between the IDE extension and cloud-based remote agents. This connection allows developers to quickly generate multiple design iterations, apply or revert changes locally, and continue development smoothly. The ability to switch tasks between local and cloud environments while preserving code state is highlighted as a major productivity booster. The speaker finds this workflow innovative and one of the most exciting recent advancements in AI coding tools, enabling a more interactive and flexible development experience.

Despite the positives, the video also points out several frustrations with the current Codex tools. One annoyance is the unclear “auto” context feature that automatically includes recent files without clear explanation or user control. Another significant pain point is the mandatory manual approval required whenever the AI creates new files, which disrupts workflow and lacks an option for auto-approval. The speaker also critiques inconsistencies in user interface interactions, such as differing key commands for submitting prompts, which can be mentally jarring. These issues highlight areas where the developer experience could be improved.

The speaker further critiques the CLI experience, noting that while it has improved and now supports authentication and integration with the IDE and remote agents, the output formatting is problematic. Large blocks of color-coded code in the terminal are hard to read and add unnecessary noise, detracting from usability. Although the CLI provides useful features like progress timers and context tracking, the presentation of code diffs and generated content feels overwhelming and could benefit from customization options or a cleaner display.

In conclusion, the video reflects a conflicted but hopeful stance toward OpenAI and its Codex ecosystem. The speaker admires the technical advancements and the power of GPT-5 for coding tasks but is frustrated by OpenAI’s apparent lack of focus on developer-centric communication and tooling polish, as evidenced by recent live streams and product design choices. They acknowledge that while competitors like Google may currently offer a better developer experience, OpenAI’s innovations remain compelling. The video ends with an invitation for community feedback and a cautious optimism about the future of AI-assisted coding with Codex and GPT-5.
