I am looking to use this in non-interactive mode, is it just setting the model as model = "gpt-5" in the config.toml or is there a more specific model name related to the recent "gpt 5 codex" release.

Any help would be appreciated

You can use /model within codex or set model = "gpt-5-codex" in your ~/.codex/config.toml file.
