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. The order is by price only.
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.
