AI API Router Directory

Vertex AI serves Google's Gemini models through Google Cloud's paid API (aiplatform.googleapis.com), with project-level billing and a choice between global and non-global endpoints; the generative-AI pricing URL now renders as the Agent Platform (Gemini Enterprise Agent Platform) pricing page. Published list prices per 1M tokens: Gemini 3.8 / 3.7 / 3.6 Flash are on introductory pricing of $0.75 input and $3.75 output through December 31, 2026, rising to $1.50 and $7.50 on January 1, 2027, while Gemini 3.5 Flash-Lite is $0.30 input and $2.50 output and Gemini 2.5 Flash is $0.30 and $2.50. The Vertex pricing page states no standing free monthly token allowance for Gemini; Google's free-tier documentation instead gives $300 in 90-day Free Trial credit and a separate free tier for many Gemini models under the Gemini Developer API (AI Studio).

Google Cloud Free Trial gives $300 in Welcome credit valid for 90 days for eligible new billing accounts (cloud.google.com/free/docs/free-cloud-features); the Vertex generative-AI pricing page itself lists no free token allowance but does include 5,000 free grounding queries per month across Gemini 3 models.

Google AI Studio gives free API access to Gemini models — free input and output tokens under per-model rate limits, not a depleting credit. Current-generation Flash models (including Gemini 3.8 Flash) are free-tier eligible. Paid tiers unlock higher limits, context caching, the 50%-off Batch API, and the most advanced models on the same API; free-tier data is used by Google to improve its products, paid-tier data is not.

Estimated based on high free-tier rate limits (RPD) vs paid input/output rates for equivalent usage.

The Gemini app is free with a personal Google Account at 'standard limits'; Google's help centre states Gemini Apps use compute-based usage limits that refresh every 5 hours until a weekly limit is reached. Free accounts get a 32k-token context window and access to Gemini Flash-Lite, Flash and Pro models, while paid tiers raise limits (Google AI Plus 2x at $4.99/mo, AI Pro 4x at $19.99/mo, AI Ultra 5x or 20x at $99.99 and $199.99/mo) and lift the context window to 1M tokens on Pro and Ultra.

No monetary credit accompanies the free Gemini tier; Google states free access has 'standard limits' with a 32k-token context window, while paid Google AI plans are $4.99/mo (Plus), $19.99/mo (Pro) and from $99.99/mo (Ultra, 5x and 20x variants).
