  • Sep 23, 2026OpenAI API Scale TierGPT-5.5 Scale Tier latency SLA listed as '99% > 100 tokens per second' in the 2026-06-11 snapshot; the live page on 2026-09-23 lists '99% > 50 tokens per second'. Exact change date unknown (between those dates).Source
  • Sep 23, 2026Anthropic Claude API Priority TierPriority Tier moved from a purchasable offer ('Get started with Priority Tier ... Higher availability: Target 99.5% uptime', still present in the 2025-11-11 snapshot) to 'no longer available for purchase' for new commitments. The 99.5% target is unchanged. Exact change date unknown; after 2025-11-11, observed 2026-09-23.Source
  • Jul 30, 2026OpenAI API Fast mode (formerly Priority processing)Priority processing renamed Fast mode ('Priority processing was renamed Fast mode on July 30, 2026'); service_tier 'priority' still accepted.Source
  • Jun 1, 2026GitHub Enterprise CloudCredit schedule changed. The June 2021 version (Wayback snapshot 2022-02-03, PDF) gave 10% of fees when quarterly Uptime was <= 99.9% but > 99.0%, and 25% below 99.0%. The current 'Version: June 2026' page gives 5% for 99.5-99.9%, 10% for 99.0-99.5%, 25% below 99.0%, so small misses now earn half the prior credit. The 99.9% quarterly commitment is unchanged. A 2025-12-31 snapshot still linked the 20210630 PDF, so the change landed in the first half of 2026; exact day not published (date set to the version month).Source
