· ai · Source ↗

TLDR

  • A new Python plugin lets the llm CLI tool piggyback on existing Codex CLI credentials to call OpenAI models.

Key Takeaways

  • llm-openai-via-codex is version 0.1a0, an alpha release by Simon Willison.
  • It works by hijacking Codex CLI credentials rather than requiring a separate OpenAI API key.
  • The plugin integrates with Simon Willison’s llm tool, which has 590 prior tagged entries on his blog.
  • Tagged under openai, llm, and codex-cli; released April 23, 2026.

Why It Matters

  • Developers with a Codex subscription can access OpenAI models through llm without provisioning or paying for a separate API key.
  • Reusing existing auth credentials lowers the setup barrier for scripting and local LLM workflows against OpenAI’s API.
