Author’s verdict
They say today's Opus 5.5 night train is worse than the launch run: small details up, overall scene down, as in their Eiffel Tower rerun.

@EnvolDev’s view (paraphrased)

Claude Opus 5.5 reruns the author's night train benchmark with the same prompt it got at launch. The author says this one is worse: small details are up but the overall scene is down, as in their Eiffel Tower rerun.

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.
