Codex

Codex is one of the easiest coding tools to connect to MetaioLab because the OpenAI-compatible path has already been verified live.

Section titled "Recommended setup"
  • Base URL: https://metaiolab.com/v1
  • Verified model example: gpt-5.4
  • Verified routes:
    • GET /v1/models
    • POST /v1/chat/completions
    • POST /v1/responses

Fastest setup

Section titled "Fastest setup"
Terminal window
export OPENAI_BASE_URL="https://metaiolab.com/v1"
export OPENAI_API_KEY="sk-your-token"

Why Codex is a strong fit

Section titled "Why Codex is a strong fit"

Codex maps cleanly onto the routes that were successfully validated on MetaioLab.

Section titled "Recommended operator defaults"
  • Use gpt-5.4 as the first documented example model.
  • Keep /v1/responses enabled because modern coding tools increasingly rely on it.
  • Tell users not to add /v1 twice.

Troubleshooting

Section titled "Troubleshooting"

Codex adds another /v1

Section titled "Codex adds another /v1"

Use the base URL exactly once:

https://metaiolab.com/v1

Requests succeed but model errors out

Section titled "Requests succeed but model errors out"
  • Verify the model name is exposed by MetaioLab.
  • Verify the model supports the requested feature.
