Try OpenAI Codex with GPT5-codex medium

The technology is progressing very fast, and that includes both the models and the tooling around it.

For example, Gemini 2.5 was considered a great model for coding when it launched. Now it is far inferior to Codex and Claude code.

The Githib Copilot tooling is (currently) mediocre. It's ok as a better autocomplete but can't really compete with Codex or Claude or even Jules (Gemini) when using it as an agent.

I'll try out Codex and see how that performs. Presumably I can just use OpenAI's Codex extension in VS Code?

Maybe, there are a few different things named "Codex" from OpenAI (yes, needlessly confusing) - "Codex" is a git-centric product, the other is the GPT-5-Codex agentic coder model. I recommend installing the Codex CLI if you're able to and selecting the model via `/model`.

  npm install -g @openai/codex
