# Comparing Anthropic Claude Code to Open AI Codex (building a 3D Knowledge Graph)

By Kamil Banc | February 28, 2026

## Claims

1. **This one is a recording**: The post is a five-minute live recording rather than a long-form written breakdown
2. **The test artifact matters**: The comparison centers on building a 3D knowledge graph as the shared implementation task
3. **Both tools are hands-on**: Claude Code and OpenAI Codex are evaluated through a practical coding exercise
4. **Builds beat benchmark debates**: The page frames tool comparison around shipping an artifact instead of abstract benchmark talk
5. **Comparison stays builder-focused**: The recording sits inside a broader body of builder-focused AI workflow content on the site

## Evidence

### Quote
> "A recording from Kamil Banc's live video." - Kamil Banc

### Key Statistics
- **5 mins**: Runtime noted in the page description
- **2 tools**: Claude Code and OpenAI Codex are the systems being compared
- **1 build**: The shared implementation task is a 3D knowledge graph

## Context
The page itself is lightweight, but its format still communicates a useful methodological choice. Instead of comparing coding agents through model scores or marketing claims, the post anchors the comparison in a single concrete artifact: a 3D knowledge graph. That makes the evaluation legible to builders because the question becomes how each tool behaves during actual implementation. It is a thin entry compared with the written posts, but it still fits the library's goal of indexing practical, source-linked operating claims.
