Introducing GPT-5.4

OpenAI announced GPT-5.4, and the RSS snippet discloses only the title and version number 5.4. The body is empty, so the post does not disclose model size, pricing, context window, benchmarks, or rollout scope; watch the full technical post, not this headline alone.

Why it matters: OpenAI naming GPT-5.4 has same-day news value, so HKR-H and HKR-R pass. HKR-K fails because the post discloses only the model name; price, context window, evals, and rollout are missing, so it stays in the 78–84 band instead of higher.
