Watch out
Now dearer than GPT-5.6 Sol on both sides — $5.00/$30.00 against Sol's $4.00/$20.00 after the 2026-08-22 cut — for a generation less capability. Nothing recommends it for new work
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.
Nothing has moved since we started tracking it.
