I'm not sure how to interpret this part: "each running its own GPT-5.6 instance".

GPT-5.6 is a closed source model and this seems to be a personal project and not something done by OpenAI.

yeah, is it API or codex?

		Poor wording on my end, thanks for flagging. I pull the OAuth refresh token from each Codex account into a custom broker, which mints short-lived access tokens per request and load-balances across the pool.
