tt-provider-gemini 0.1.0

//! Pricing table for Google Gemini models (May 2026 baseline).
//!
//! Values sourced from the Google AI pricing page.
//!
//! # Pricing brackets
//!
//! Gemini uses a two-bracket pricing model based on prompt size:
//! - ≤200K input tokens: standard rate
//! - >200K input tokens: higher rate (approximately 2× standard)
//!
//! `ModelPricing.input_per_million` uses the ≤200K rate as the headline
//! rate, since most requests fit. When a request exceeds 200K input tokens,
//! a `tracing::debug!` is emitted. Full bracket support is a v2 enhancement
//! to the pricing struct.
//!
//! # Cache pricing
//!
//! `cached_input_per_million` is the cached-read rate (approximately 10% of
//! the standard input rate). Cache-write surcharges are not exposed here.
//!
//! Rates come from the versioned, embedded pricing catalog
//! (`tt_shared::pricing`); the headline rate is the ≤200K-token bracket.
