Launch prices for models released since 5 Mar 2026, when this log begins; older models appear from the date we first recorded their price, so no launch price is guessed. List prices in US dollars. Hosted open-weight models show the cheapest host when we checked; their price changes are dated when we saw them, as hosts don’t announce them.
