Prices through OpenRouter
Batch variants (15)
OpenRouter lists these as separate batch variants at a different price; batch requests are not answered right away, so these prices are kept apart from live prices.

Unknown means no value was recorded at our latest check; it is never shown as zero. Prices in USD as OpenRouter lists them; we do not add taxes.
How these numbers are produced
Each row is one model at one provider in our ai-models section. Prices are the input and output prices per one million tokens from the latest check of that model; the context length is the value read on the same pass. The table is sorted by our latest output price, lowest first; rows without an output price come last, and after them, greyed, rows of providers whose terms restrict independent comparisons (list of these providers).
A provider gets its own page when we track at least 5 of its models.
Each model links to its page with dates, the source link and the full history.
