Codex Rising Against Claude Code

The Competition Never Ends

For the past few weeks I’ve been using OpenAI’s Codex, and I keep handing it more of my work. Claude Code used to be my default, but now Codex has earned a permanent seat at the table.

Here’s what I’ve learned.

1. Codex is a Much Better OpenClaw

Codex can do almost everything OpenClaw does, while it’s 10x easier and safer to use Codex then OpenClaw. Also Codex’s performance is much stronger than OpenClaw.

2. Codex hallucinates less than Claude Code

Codex is more deliberate and reliable. It follows prompts precisely, stays on mission, and produces cleaner, higher-quality output with fewer bugs.

Claude Code is faster and more “creative,” but it can feel rushed and it often ignores custom instructions, including the rules I’ve spelled out in .md files.

The two complement each other nicely. For a major task or project, I’ll ask Claude Code to brainstorm and plan, then hand the implementation off to Codex.

3. Use Codex as a counterparty to Claude Code

When I’m vibe coding or running investment analysis, Codex makes a great second pair of eyes: a doublecheck, verifier, and challenger for Claude Code’s output.

You could spin up multiple agents inside Claude Code to play this role, but Codex brings something Claude Code can’t: a fundamentally different model with its own reasoning style and perspective. And GPT-5.5 is probably the smartest LLM out there right now, so the second opinion is worth taking seriously, a must-have.

4. Codex generates superior infographics

Codex directly produces images using GPT Image 2, the strongest AI image model on the market. This enables Codex to be a superior infographic generator.

a. Infographic for newsletter summaries

I asked Codex to summarize every post from a dozen of top newsletters in the past three months and generate a strong infographic based on the research.

b. Infographic for YouTube trending topics

I asked Codex to search and summarize top AI use cases in stock investments in the past 3 months and below is the infographic report.
