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 share of a shared set of problems the model solved (%).
  • ± is how far the score moves when re-measured, 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
  • Its successor is Tier 4 v2, which fixed problems with errors. The value is accuracy.
  • 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.
