    Price cut from $20/$2/$120 to $12.50/$1.25/$75, found only in captures: the 2026-06-21 capture still shows $20/$120, the 2026-06-24 capture shows $12.50/$75. No changelog entry or announcement found. LiteLLM never saw the $20 price (it first lists the key on 2026-09-14). The pricing table lists these rates under 'Short context' and shows '-' for every long-context column, so rates for prompts over 272K tokens are unknown.

    First listing on the pricing page. The row sits in the collapsed part of the Specialized models table (Cyber group), so it appears in the page data rather than the default view. The 2026-05-28 capture has no gpt-5.5-cyber row. The pricing table lists these rates under 'Short context' and shows '-' for every long-context column, so rates for prompts over 272K tokens are unknown.

Gaps in this history

No pricing-page listing before 2026-06-05 (launched in limited preview 2026-05-07). Exact date of the June 2026 price cut unknown (between 2026-06-21 and 2026-06-24 captures). No batch or long-context prices listed; no cache-write price ('-').
