Watch out

Audio input is priced at 2x text — separate your modalities when estimating. Google's deprecations page now gives it an earliest shutdown of 2027-05-07, with Gemini 3.5 Flash-Lite as the replacement

What this has cost, week by week

Output price at each refresh since 2026-07-30. A vendor change is the provider changing its price. Our correction means this board changed what it prints and the provider's charge did not move — the two are never merged, because publishing the second as the first would be a price rise that never happened.
