"Superhuman" refers to abilities, qualities, or powers that exceed those naturally found in humans. It implies being greater than normal human capabilities.
The term is often used in fiction, particularly in superhero comics and fantasy, but it can also be used metaphorically to describe extraordinary effort or achievement in real life (e.g., "It took a superhuman effort to finish the marathon").
(Definition from Gemini)
It seems reasonable to use the term to me simply to say the abilities on a benchmark of the model were greater than the human annotated data. Computers have always been superhuman at many tasks, even before llms.
On a separate note, using an LLM for a definition is a bit funny, when there are expert-curated sources easily available. The LLM didn't get it wrong here, but...

First line: "The term superhuman refers to humans, humanoids or other beings with abilities and other qualities that exceed those naturally found in humans."
Golly, I wonder what that model based its first sentence on.
