Free & discounted OpenRouter models

Fetched directly from the public OpenRouter model catalog at 2026-09-06T20:49:18.039Z. Free means the prompt and completion prices are both exactly zero — read from pricing, not from the :free suffix, which is a naming habit rather than the fact. Unknown pricing is never treated as free. Discountis the conditional pricing OpenRouter publishes per model (off-peak UTC windows and volume tiers), shown as the saving against that model’s most expensive rate; the Input column is the headline rate, which for these models is the cheap end of the range. Separately, "Cheapest 20%" marks models whose combined prompt+completion price is at or below $0.57 / 1M tokens — a ranking, not a discount.

Published discount is a different fact again: a straight percentage off list price that a named provider publishes for its endpoint. It is not on the model — no model in the catalog carries a discount key — it is one level down, on the provider endpoint, which is why this page previously reported that OpenRouter published no discounts at all. Endpoints are collected under a daily request budget, so coverage is partial: 52 models have an observed endpoint and 4 of those carry a non-zero discount. A dash means no endpoint has been observed for that model yet — it does not mean there is no discount.
