Fetched live 2026-11-03. ## Usage tiers (billing-history gated, not a self-serve toggle) | Tier | Qualification | Spend cap | |---|---|---| | Free | active project or free trial, no billing account | n/a | | Tier 1 | billing account linked | $250 | | Tier 2 | $100+ cumulative spend AND 3+ days elapsed since Tier 1 | $2,000 | | Tier 3 | $1,000+ cumulative spend AND 30+ days elapsed | $20,000-$100,000+ (varies) | Tier 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. ## Rate-limit dimensions Three 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. ## No documented rate-limit response headers Unlike 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. ## Model lifecycle / deprecation notice Google'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.
