Fetched live 2026-11-03.\n\n## Usage tiers (billing-history gated, not a self-serve toggle)\n| Tier | Qualification | Spend cap |\n|---|---|---|\n| Free | active project or free trial, no billing account | n/a |\n| Tier 1 | billing account linked | $250 |\n| Tier 2 | $100+ cumulative spend AND 3+ days elapsed since Tier 1 | $2,000 |\n| Tier 3 | $1,000+ cumulative spend AND 30+ days elapsed | $20,000-$100,000+ (varies) |\nTier upgrades from Free->Tier 1 are instant; Tier 1->2->3 take up to 10 minutes to apply once both conditions (spend + elapsed time) are met — a dual gate, not spend alone.\n\n## Rate-limit dimensions\nThree independent axes, documented as varying \"by a variety of factors\" (no single universal number given on this page — actual per-model values live in AI Studio, not the docs page): **RPM** (requests per minute), **TPM** (input tokens per minute), **RPD** (requests per day). Paid tiers ALSO carry a rolling 10-minute spend-rate cap layered on top of the RPM/TPM/RPD axes: Tier 1 $10/10min, Tier 2 $200/10min, Tier 3 $200/10min — so a high-RPM, high-token-count request pattern can still 429 purely on spend velocity even inside the RPM/TPM/RPD budget.\n\n## No documented rate-limit response headers\nUnlike OpenAI, Anthropic, Groq, or Hugging Face, this page documents no `X-RateLimit-*` (or Google-style `x-goog-*`) rate-limit header at all. The only documented signal is the error body itself: HTTP **429** with gRPC-style status `RESOURCE_EXHAUSTED`. A caller gets no machine-readable \"how much is left\" value from headers — only the binary pass/429.\n\n## Model lifecycle / deprecation notice\nGoogle's documented minimum: a retirement gets a fixed shutdown date with \"at least 45 days\" migration notice; preview models get a shorter \"at least two weeks\" notice; a `-latest`-style alias getting swapped to a new underlying model also carries two weeks' email notice before the swap. Third-party trackers (not re-verified live in this record) have reported the Gemini API and the separate Cloud/Vertex model-lifecycle pages carrying different shutdown dates for what looks like the same model name — flagged as a cross-surface risk, not independently confirmed here.\n\nHow observed: 2026-11-03T11:49Z, documentation fetch (actual header/tier behavior requires a billed account to observe live; recorded from current published docs).","content_hash":"sha256:c41bb83a3146f41e9ff8936bebc93be547aae2c6736c78215cd26d742cd65b0a","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?
