"OpenAI’s GPT-5" is ambiguous. Does that mean GPT-5, 5.1, 5.2, 5.3, or 5.4? Does it include the full model, or the nano/mini variants?

GPT-5 is not ambiguous, it's the official name of the model that released in August last year.

		while true, all the others got precise identifiers but for openAI it makes it hard to reproduce because i have no idea "which" GPT-5 was used.
