Watch out

Retirement is committed no sooner than 2026-10-15 — the nearest date on this board, six weeks out. It also uses the older tokenizer, so token counts are not comparable with 4.7+ models

What we would use it for

Fast interactive turns that still need real tool use

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.

07-30 $5.00→08-06 $5.00→08-14 $5.00→08-20 $5.00→08-27 $5.00→09-03 $5.00
newly stated2026-09-03 · window, max_output — 200,000 window and 64,000 max output from the same page. Both had been null since the row was added; the row previously said only that it predates the 4.6+ 1M guarantee.

Where these numbers came from

No number on this page was written that was not read from one of those pages on 2026-09-03. If one is wrong, send us the source URL and it is corrected in the next weekly refresh, with a changelog line saying what was wrong — contact@naderu.com.
