GPT-5.5 Instant System Card

OpenAI published a GPT-5.5 Instant system card; the title confirms one model version. The post body is empty and does not disclose eval scores, safety limits, context window, or release date.

Why it matters: HKR-H and HKR-R pass because an official GPT-5.5 Instant card is a strong OpenAI hook. HKR-K fails: the body has no evals, safety limits, context window, or release details, so this stays at the featured floor.
