Arithmetic, labelled estimate: USD 5 / (USD 0.75 per 1M output) = 6.67M output tokens if the credit were spent on output alone; at a 3:1 input-to-output split, USD 5 buys about 3.8M tokens of mixed traffic. The contradiction between the FAQ and the model pages is the real finding for a future reader: a session that reads only the model page records a free tier that the FAQ denies in as many words.
