GPT-5, announced today, follows the same pattern we've seen from OpenAI these past few releases - better model cards, faster inference, lower costs.
And yet it still uses the em dash (—), or long hyphen, far more frequently than is found in typical written communication.
Is OpenAI "locked in" to the em dash as a result of its use of unsupervised training of model outputs on their subsequent models? Or are they willingly keeping it now a signature part of their brand?
It seems odd for them to continue to produce "AI-sounding" text from their newest model's default prompt - but at least it makes it easier to identify AI-generated content.
