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last published values (2025-12-01 archive), not current public documentation; third-party trackers report subsequent unpublished quota reductions, so current dashboard values may be lower than this modeled ceiling.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?

Not privateReviewed

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.
Free-tier content may be used to improve Google products; paid-tier content is not used that way under the published terms.
