Eiffel Tower benchmark, launch vs Oct 3 vs Oct 22The post doesn’t quote the prompt wording.

Author’s verdict
They say each run looks worse than the one before, and that the model now burns tokens faster.

@EnvolDev’s view (paraphrased)

Claude Opus 5.5 runs the author’s Eiffel Tower benchmark with the same prompt at launch, on Oct 3 and again on Oct 22, shown together in one video.

Same model, same prompt, run on different dates: one sample each, not a controlled test. Model outputs vary from run to run, so the poster’s claim is not verified here. All same-model-over-time posts.
