Which tier fits
Free suits prototypes and small projects: free input and output tokens on certain models, including Gemini 3.8 Flash and Gemini 3.5 Flash-Lite, plus Google AI Studio. Your content is used to improve Google's products, and Gemini 4 Argon and Gemini 3.1 Pro Preview are not offered on it.
Paid is for production: higher rate limits, context caching, the Batch API and Google's most advanced models, and your content is not used to improve Google's products.
Enterprise runs through Gemini Enterprise Agent Platform, with optional dedicated support, provisioned throughput and usage-based volume discounts. Google notes its prices may differ from the Gemini API's.
Contributor is an invite-only private preview at Standard-tier speed; Gemini 3.5 Flash-Lite costs $0.15 input and $1.25 output per 1M tokens on it, and your content is used to improve Google's products.

How the bill adds up
Tool use adds its own charges: Search grounding on Gemini 3 and newer models includes 5,000 free requests a month and then costs $14 per 1,000, while Gemini 2.5 Pro allows 1,500 free a day and then charges $35 per 1,000 grounded prompts. Code execution and URL context are billed as tokens, and managed agents pay token rates with sandbox compute unbilled during the preview.
Google's worked figures
Images: Nano Banana 2.1 image output under Standard processing is priced at $30 per 1M tokens, so a 1K image (1,120 tokens) is equivalent to $0.0336, a 2K image to $0.0504 and a 4K image to $0.113.
Speech: at 25 audio tokens per second, Gemini 3.8 Flash TTS output under Standard processing at $9.00 per 1M tokens equals $0.00225 per 10 seconds of audio through December 31, 2026.
Video: Gemini Omni Flash bills 5,792 output tokens per second of 720p video, which Google puts at about $0.10 per second on Standard pricing.
Costs that are easy to miss
Thinking tokens are billed at the output rate.
One prompt, several searches: a request can trigger more than one Google Search query, and each is charged, although the retrieved search context is not charged as input.
PDFs are billed at the image token rate.
Cache storage runs by the hour: $0.50 per 1M tokens per hour on Gemini 3.8 Flash through December 31, 2026, and $4.50 on Gemini 3.1 Pro Preview under Standard, Batch and Flex processing ($8.10 under Priority).
Our take
Prototype on the Free tier with Gemini 3.8 Flash or Gemini 3.5 Flash-Lite. Move to Paid when you need higher rate limits, context caching, the Batch API, or content that is not used to improve Google's products. Budget Gemini 4 Argon and Gemini 3.8 Flash at their December 2026 and January 2027 rates rather than today's.
