Is ChatGPT Codex reliable for large projects?

No, users report that it becomes unreliable on longer, high-scope work. It may change the project scope or produce incorrect outputs, requiring significant supervision.

What coding tasks does Codex handle best?

It works best for small, controlled tasks like debugging, code review, database operations, calculations, and investigating specific issues.

Can Codex help with non-coding tasks?

Yes, users automate repetitive tasks like cleaning promotional emails from inboxes and organizing journals, task lists, and personal information.

How can I get better results from Codex?

You can ask the chatbot to write detailed, long prompts for Codex based on what you want. Providing clear constraints for small pieces of work also yields the best results.

Are there concerns about token usage?

Yes, some users feel that high token consumption with newer models makes the service feel less valuable for the monthly cost.

ChatGPT Codex Advantages for Coding and Automation

ChatGPT Codex improves developer productivity by automating small, well-defined coding tasks like debugging, code review, and database work. It also handles repetitive chores such as cleaning inboxes or organizing files.

Users find it great for rapid prototyping and content generation, getting better results when they use detailed prompts to guide the tool. One useful trick is asking the chatbot to write the long prompts for Codex.

However, reliability drops on large, complex projects where it might change the scope or produce incorrect outputs that require heavy supervision. Some users also worry about high token consumption affecting the overall value.

ChatGPT Codex is a powerful tool for developers, offering several benefits, particularly in automating and streamlining coding tasks and enhancing productivity for specific, well-defined projects. It excels at smaller, focused tasks but can be less reliable for larger, complex autonomous projects.

Debug and Review Code: Codex is highly effective for identifying bugs and performing code reviews, making the debugging process more efficient. "For me Codex was useful for small tasks like debugging and code review."

Database and Calculation Work: Users find it proficient in handling database operations and various calculations. "I liked it for finding bugs, cross-reviewing code, database work, calculations, and investigating a specific issue."

Project Prototyping: It can quickly generate prototypes, especially when guided with detailed prompts. "Best I found out is telling chatgpt what you want and asking chatgpt to write full long prompts for codex works way better than doing it myself."

General Productivity and Automation

Automate Tedious Tasks: Codex can automate repetitive tasks, such as cleaning up email inboxes or organizing files. "I used it last week to clean out promotional emails from my inbox using the Gmail plugin; I just had it run on a loop to delete and unsubscribe from promotional emails until my inbox was clean."

Content Generation and Organization: Beyond coding, it assists with generating content like cover letters and organizing personal information, journals, and task lists. "I have an Obsidian journal setup with different sections, including daily/weekly task lists, references, open projects, etc."

Rapid Development: For those who learn to leverage its capabilities, Codex can significantly accelerate development processes for various applications, including websites, apps, and games. "One can do wonders if they know how to use AI to get what they want."

Usage and Limitations

Small, Controlled Tasks: Codex performs best with narrow, well-bounded tasks where constraints are clearly defined. "If I give it a small, controlled piece of work and review the result carefully, it can be useful."

Challenges with Large Projects: For longer, higher-scope work, Codex can become unreliable, sometimes changing the project scope or producing incorrect outputs, requiring significant supervision. "The problem is that this reliability did not scale to longer-running, higher-scope work."

Token Usage Concerns: Some users report high token consumption, especially with newer models, impacting the value for money. "This one-prompt-a-week crap is not worth the 20 a month."
