YES if, by July 1, 2026 11:59 PM ET, OpenAI publicly states in its API docs, model docs, or product announcements that gpt-5.4 or gpt-5.4-pro is available in the public API with a 1M-token context window.
NO otherwise.
Resolution notes:
Private previews, internal use, or Codex-only experimental access do not count.
If only a different model gets 1M context, this resolves NO.

1,000Source context: OpenAI's GPT-5.4 launch says GPT-5.4 is in the API now, while 1M context is currently called out only for Codex as experimental support. This market is about whether that 1M window reaches the public API for GPT-5.4 itself before July. Official source: https://openai.com/index/introducing-gpt-5-4/
