Published discounts: a prompt-cache read rate for 43 of the 52 and a batch rate for 34 of the 52. The most recent release date, 2026-09, is shared by 8 of them. Arena ELO scores (as of 2026-10-02) exist for 19 of the 52; the highest is GPT-5.6 Sol at 1484. Image models, 3 of them, also bill per image: they are listed on token price and left out of the cheapest and most expensive above. Those marked deprecated, 9 of them, are under a retirement notice from the model maker: models to migrate off, not to start on.
