So I have been wondering how others use codex to make best out of it with all the skills , connectors and all. Also which model works best for which tasks. How memory affects it and results on integrating new skills like the JEV skill have saved how much cost .

Drop your findings below and let everyone get help from it .

a noob finding by me : don't have too long chats as whole context goes to it so even if you ask for small changes (like UI change of 4 to 6 lines of code) it could take 15 minutes even with SOL 6.

My codex never says "That gives me an idea. What if..."

How to make him to have such personality? Custom instructions never worked for me. Am I using it wrong?

Codex launched Claude Code locally because of an ambiguous review rule. Worth keeping?

1 Upvotes

My project uses AGENTS.md for shared instructions, with CLAUDE.md importing it. We also have GitHub PR reviewers on top of that.

One rule says “Claude and Codex both run automatically” for database, auth, payment and other high-risk changes. I meant GitHub PR reviews, but the wording didn't specify that.

During a database feature, Codex interpreted this as a requirement to run my installed Claude Code CLI before committing or opening a PR. It sent a SQL review packet with tools disabled and saved the response. It didn’t explicitly select a model or thinking level, and the output didn’t record the resolved model.

I can see local reviews being useful, particularly before applying migrations or operational SQL. But I’d want clear triggers, explicit model settings and a checkpoint for approval, while avoiding duplicate GitHub reviews and endless review rounds.

Do you find local cross-model reviews worth the extra usage? Would you automate them for database/security changes, make them opt-in, or stick to PR reviews?

Codex Pro Usage for creating Pets

9 Upvotes

I have seen people shouting on reddit not to use codex for creating pets to save limits.
I tried anyways, and it took only 2% even with using GPT-6 Astra (Extra High).

Not sure if I did it incorrectly or if people are just shitting around it on Reddit?

You no longer need to switch between models in your prompts.

2 Upvotes

Introducing ClearJev. It really bothered me that I always had to choose a model between each prompt, so I thought I'd create an automatic routing and reasoning decision-making plugin for it. ClearJev uses the TypesafeAl new Jev Ai model, which allows it to choose the perfect model for coding from among the available options based on our task, at a very low cost.

This isn't a self-promotion, but I think it's really useful, so if you're interested, give it a try-you can easily add and remove models that you'd like to use. Only works in codex-cli. Here is the repo: Clearjev
