Grading short stories (Lech Mazur Writing)

The model writes a short story that must use every required element, such as a character, an object and a setting, and several grader models score it.

How to read this table

  • Higher rows are rated higher. A range like “1–2” means the gap is within the margin of error.
  • The score is the value published by the task's authors and other organizations.
  • Conditions can differ between models, so small gaps do not mean much.
  • Prices are a guide per million tokens, reading then writing.
  • Length is how much text the model can read at once (tokens).

How to read this page
  • The value is the 10-point average rescaled to 100. Figures published by the organizations that made the tasks, among others, collected here.
  • The average grade rescaled to 100, and most models score 60 to 90. No error margins are published, so differences of 1 to 2 points are not clear differences.
  • In the Supports column the icons are, from left: can use tools / can read images / can answer in a fixed format (JSON); faded means not supported or unknown.
  • Open-weights models have their contents (the weights) published, so you can also run them on your own computer or server. Models without the open-weights mark are normally used through the developer's own services (apps or API); for some models the weights status is unknown.
  • Names such as ChatGPT next to a model are the consumer services its developer offers. Check on the service itself whether that model is available there.
