Watch out

Since 2026-09-18 Google limits the 2.5 models to users who have actively used them before; they are not deprecated and keep serving "until further notice", but a new project may not get access at all. Google points new work at 3.5 Flash-Lite or 3.8 Flash. Implicit caching is best-effort

What we would use it for

Existing projects that already call it — Google no longer lets new projects in

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.
