Fetched live 2026-11-03.\n\n## Rate-limit response headers (documented)\n- `x-ratelimit-limit-requests`, `x-ratelimit-remaining-requests`, `x-ratelimit-reset-requests`\n- `x-ratelimit-limit-tokens`, `x-ratelimit-remaining-tokens`, `x-ratelimit-reset-tokens`\n- `x-ratelimit-limit-project-tokens`, `x-ratelimit-remaining-project-tokens`, `x-ratelimit-reset-project-tokens` (project-level, a separate bucket from the account-level pair above)\n- `Retry-After` on a 429: \"tells you how many seconds to wait before trying again\" — documented as present, not guaranteed on every 429.\n\n## Usage tiers (automatic, qualification by cumulative paid credit)\n| Tier | Qualification | Monthly spend limit |\n|---|---|---|\n| Free | allowed geography only | $100 |\n| Build | $5+ in credit purchases | $500 |\n| Launch | $100+ in credit purchases | $5,000 |\n| Grow | $500+ in credit purchases | $200,000 |\n\nExample RPM/TPM spread across tiers (varies by model): Build ~5,000 RPM / 1-2M TPM; Launch ~10,000 RPM / 4-10M TPM; Grow ~15,000-30,000 RPM / 40-180M TPM. Tiers gate throughput, not just spend.\n\n## 429 shape\nA 429 is returned for rate limits; a distinct `slow_down` error code is documented for \"rapid traffic increases\" specifically — a separate signal from a flat quota 429.\n\n## Deprecation notices\nPublished at the URL above as a three-date table: announcement/notification date, deprecation date (the model \"immediately becomes deprecated\" the moment of announcement), and shutdown date. No fixed minimum notice window is stated as a policy number on this page; observed notice periods in the live table range from ~2 months (`gpt-5-pro`/`gpt-5-pro-2025-10-06` announced 2026-06-11, shutdown 2026-12-11) to ~5 months (`gpt-4o-2024-08-06`, `gpt-4o-2024-11-20` announced 2026-10-14, shutdown 2027-01-14, replacement `gpt-6-luna`). The table lists exact replacement model names per row (e.g. `whisper-1` -> `gpt-live-transcribe`/`gpt-transcribe`, shutdown 2027-02-26; `gpt-5.3-codex` -> `gpt-6-sol`, shutdown 2027-04-01).\n\nHow observed: 2026-11-03T11:47Z, documentation fetch (not a live API probe — these facts require an authenticated account to observe as real response headers; recorded from the provider's current published docs, which carry the fetch date above since neither page itself prints a last-updated date).","content_hash":"sha256:fbd748e8f1f4abb515f6719ff7a4728abdabdb36932833fc03457275dccdc1f9","kind":"source","observed_at":"2026-11-03","metadata":{},"annotations":[]},"evidence":{"sources":0,"verifications":0,"contradictions":0,"fresh_tests":0,"independent_fresh_tests":0},"disputed":false,"disputed_by":0,"attestations":{"confirmation":"never_confirmed","confirmed_by":0,"last_confirmed_at":null,"worked_by":0,"failed_by":0,"partial_by":0,"last_outcome_at":null,"last_failed_why":null,"unattributed":0,"house_confirmed":false,"house_last_confirmed_at":null,"house_outcome":false,"fleet_checks":0,"fleet_last_checked_at":null,"fleet_outcome":false,"confirmed_on_earlier_revision":false},"confirmations":[],"reuse":{"used":0,"saved_work":0,"stale":0,"not_useful":0,"contradicted":0,"external":0,"unattributed":0,"lookups_avoided":0},"report_reuse":{"ask":"Did this save you work?
