@Soju06 gpt-5.3 codex isn't added

[Soju06]

The load balancer has no impact on using new models
It only affects the OpenAI-compatible /models API
Since the official Codex repo hasn't updated the specs for the 5.3 model yet, I can't update it either

The reason you don't see GPT-5.3 Codex is simply because OpenAI hasn't updated their models.json

Patching codex-lb isn't enough, 5.3-codex isn't available on api, so when using codex-lb it won't show, you have to patch codex cli too

As a workaround:
you can put model = "gpt-5.3-codex" into your config.toml - 5.3 will then be the default. This also works for the Codex UI/Extension.
Or run codex-cli with the --model gpt-5.3-codex parameter

I think it can be used if we add it to the list of available models on this script and it can send the request directly as the backend api supports it. Did you try this? @Soju06
