OpenAI SLAAI vendor · Uptime guarantee, credits and support

Status history since Sep 9, 2026

• ChatGPT EnterpriseAI models · measured other

  Page (openai.com/chatgpt/enterprise redirects to chatgpt.com/business/enterprise) says only 'Includes 24/7 support with SLAs. You can add premium support for faster responses, a dedicated contact, and on-call availability.' No uptime % or response-time numbers are public.

• OpenAI API (Standard / pay-as-you-go processing)AI models · measured other · SLA of Dec 1, 2025

  The OpenAI Services Agreement (fetched 2026-09-23) contains no uptime or service-credit schedule; section 12.2 says 'THE SERVICES ARE PROVIDED "AS IS."' subject to a warranty that Services conform to the Documentation. Published SLAs exist only for Scale Tier (and, per docs, Fast mode on eligible Enterprise agreements).

• OpenAI API Fast mode (formerly Priority processing)AI models · measured other

  Docs FAQ: 'Fast mode for GPT-6 Astra does not include a latency SLA. For GPT-5.6 and earlier models, Fast mode and Scale Tier receive the same service-level agreement treatment, and eligible Enterprise agreements may provide service credits when latency targets aren't met.' No numbers are stated on the Fast mode page itself, so tiers is empty (the Scale Tier numbers may apply by reference but that is not stated explicitly).

• Sep23OpenAI 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
• Jul30OpenAI 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
• Aug10OpenAI API Scale TierLatency SLA methodology changed from 'average request latency on per minute basis across the month' (e.g. GPT-4o 99% > 25 tokens/s in Aug 2024) to 'p50 request latency on a per 5 minute basis'. Change occurred between the 2025-04-04 and 2025-08-10 archived snapshots; uptime stayed 99.9%.Source
