How this was valued: Modeled best-case rate-limit envelope for gemini-2.5-flash, the only current free-tier model whose per-model free limits Google ever published. Google's current rate-limits page (updated 2026-08-18) states quotas are viewable only in the AI Studio dashboard, so the request-rate ceilings are modeled from Google's last publicly published free-tier table (rate-limits page as archived 2025-12-01: 10 RPM, 250,000 input TPM, 250 RPD for Gemini 2.5 Flash). Per-request ceilings are the model's current documented specs (1,048,576 input-token limit, 65,536 output-token limit), and prices are Google's own current paid text rates for the same model ($0.30 input / $2.50 output per 1M). Assumes uninterrupted saturation with maximal-context requests and no latency, concurrency, availability, or fair-use loss. Costlier free-tier models exist (gemini-3.5-flash at $1.50/$9.00, gemini-3.7/3.6-flash at $0.75/$3.75) but have never had published per-model free limits at any date, so they are excluded rather than modeled.
Partial because the RPM/TPM/RPD inputs are Google's last published values (2025-12-01 archive), not current public documentation; third-party trackers report subsequent unpublished quota reductions, so current dashboard values may be lower than this modeled ceiling.

What happens to your prompts?
Unpaid-service inputs and outputs may be retained and used to improve and train Google models.
- Plan Scope
- Gemini Developer API and Google AI Studio unpaid quota; paid services and EEA, Switzerland, or UK treatment differ.
- Prompt Retention
- Unpaid-service content may be retained and used for product and model improvement. Abuse-monitoring data is retained for 55 days. Feature-specific storage includes grounding data for 30 days and optional or stateful logs with configurable retention.
- Response Retention
- Generated responses follow the same unpaid-service, abuse-monitoring, and feature-specific rules.
- Ordinary Logging
- Google may log prompts, context, and outputs for abuse monitoring. Paid-project user logs are optional except stateful features and default to a maximum 55-day retention.
- Model Training
- Unpaid-service inputs and outputs may be used to improve and train Google models. Paid-service content is not used for product improvement without permission; EEA, Swiss, and UK unpaid use receives the paid-service data treatment.
- Product Improvement
- Allowed for unpaid services outside the stated regional exception. Paid logging datasets can be voluntarily shared for improvement and training.
- Human Or Operator Access
- Authorized human reviewers may read, annotate, and process unpaid-service content and content flagged for abuse review; Google says identifiers are disconnected before improvement review.
- Subprocessors And Routing
- Google and its service infrastructure process content; grounding and other integrations introduce feature-specific handling under the additional terms.
- Deletion Controls
- Paid-project logs can use 7, 14, 28, or 55-day retention; datasets persist without a fixed period, files remain until deletion or expiry, and stateful features require explicit configuration for zero-retention behavior.
- Caveat
- The free tier has materially different data-use terms from the paid tier, and users are told not to submit sensitive, confidential, or personal information to unpaid services.
