GPT-5.4 stumbles on creative translation

This is the kind of narrow eval that cuts through generic model hype: creative translation exposes whether a model can preserve voice instead of just delivering clean literal output.

• –The reviewer ranks GPT-5.1 above GPT-5.4 and says 5.1 is about to be retired, turning a model-quality complaint into an access problem for power users.

• –Because this is a single Reddit post, it should be treated as an early signal from an engaged user rather than a definitive benchmark result.
