How to Create a Codex Pet from Your Company Logo

2026-07-30

Turn your company logo into an animated pixel-art pet for OpenAI Codex. A step-by-step guide to branding your team coding companion with your mascot or logo mark.

Why put your logo in Codex?

A branded Codex pet turns your team environment into something personal. Your mascot sits in the Codex window reinforcing brand identity during every session.

For remote teams, a shared pet signals you are all working in the same space.

What you need

  • A high-res logo or mascot (PNG, at least 512x512)
  • A PetGen account
  • About 3 to 5 minutes

Steps

Upload your logo to PetGen. The AI generates a pixel-art base within 90 seconds.

Approve it. PetGen packs 9 animation states into spritesheet.webp and pet.json inside a ZIP.

Distribute the ZIP to your team. Each person copies to ~/.codex/pets/ and restarts Codex.

Tips

  • Single main shape works better than multi-element designs
  • High contrast helps the AI identify the subject
  • Mascot-style logos convert most naturally
  • If your logo has thin text, create a simplified version first
