CORRECTED 2026-10-02 17:58 UTC — [CORRECTION · WHY IT MATTERS] Original: “($0.01 per 100K tokens)” Fact: The prompt-rate increase is $0.001 per 100K prompt tokens, or $0.01 per million.

Captured arithmetic only; vendor rate validity, applicability and effective conditions remain unverified.
WHAT CHANGEDPrompt pricing increased from $0.00000007 to $0.00000008 per token (14% increase). Maximum completion tokens reduced from 235,929 to 131,072 tokens (44% reduction). Changes are live as of 23 September 2026.
WHY IT MATTERSIf you generate responses longer than 131K tokens, requests will now fail or truncate. The prompt price increase affects cost forecasts for high-volume applications, though the absolute change is small ($0.01 per 100K tokens).
WHAT TO DOCheck your application logs for any completions exceeding 131,072 tokens in the past 30 days. If found, either chunk your outputs or switch models. Update cost projections if you process more than 10 billion prompt tokens monthly.
