OpenAI’s GPT-5.4 series currently trails the HLE leaderboard, with GPT-5.4 Pro scoring roughly 41-58% depending on the evaluation, behind leaders such as Claude Fable 5 or Mythos 5 at 53%+ and Gemini 3.1 Pro Preview near 45%. Progress has accelerated from single-digit results in early 2025 to the mid-40s range through successive reasoning-model releases and agentic techniques, but no major OpenAI update has shipped in the past month. With only two weeks until June 30, trader sentiment hinges on whether an imminent internal scaling run, fine-tune, or public preview can close the gap before the cutoff; historical release cadence suggests limited room for surprise jumps in that narrow window.
