not published = we could not confirm this figure on the vendor's official page in this check, so we don't show a number. checked weekly = the vendor's page blocks automated checks, so we review it by hand once a week. All prices in USD before tax; each row shows the date it was last checked.
Long-context, batch, cached and fast tiers are priced differently; follow each source link. Google's Gemini 4 Argon and 3.8 Flash have promotional prices with set end dates (shown in notes).
