You can however for now use wrappers which are not harnesses such as T3Code though. They were going to cut under the Programmatic API, but have at least temporarily walked it back.
You absolutely can; they are not banning anymore. The bigger problem is that subscription versions of the models are way crappier than when the "same" model is hit via API (Bedrock/Vertex)
You can also make it not count against extra usage.
OpenCode docs show it because Anthropic specifically ambushed them with a PR to remove support so simpletons can't use it easily.
They aren't banning it anymore, they just make it count as "extra usage". e.g. you're paying for every token in addition to your subscription.
Further, the claim that the subscription "version" of the model is worse sounds like bullshit (and the sort of anecdotal nonsense that you see on sites like this). Do you have anything substantiating this?
You can use Codex with any endpoint compatible with OpenAI Response API[1], like llama.cpp.

FWIW Claude Code works with OpenRouter so you can use any model.
CC system prompt is bloated, use Pi to test Codex instead
Codex is open source and lets you use any model https://learn.chatgpt.com/docs/config-file/config-advanced#o...
Only its CLI is open source. The desktop app is always proprietary.
Codex CLI is open source too. I don't think there is a difference.
Can't use a claude code subscription in another harness though

Don't use providers that don't allow it.

The opencode docs[0] still say otherwise, do you have a source?

I am curious about the claim that the subscription models are different. Has anyone benchmarked this?

This is not at all aligned with my experience. Do you have a source for this?
