Gemini API Pricing (October 2026)
The Gemini API costs $0.75/$3.75 per million input/output tokens for Gemini 3.8 Flash, Google's newest Flash model, at an introductory rate that runs through December 31, 2026. Gemini 3.1 Pro costs $2/$12 on prompts up to 200K tokens, and Gemini 3.5 Flash-Lite costs $0.30/$2.50. The lowest current standard rate is Gemini 2.5 Flash-Lite at $0.10/$0.40. Google publishes 50%-off Batch input and output rates.
Google Gemini token pricing has three lanes: Pro for frontier reasoning ($2/$12), Flash for the price-performance middle ($0.75/$3.75 on 3.8 Flash), and Flash-Lite for high-volume work ($0.30/$2.50 on 3.5 Flash-Lite). Pro prompts above 200K tokens use a higher meter. The table lists every priced Google text model in BenchLM's registry using the standard paid tier from the Gemini Developer API pricing page.
Whether the rates are worth paying is a benchmark question, not a pricing one: see the Gemini model rankings and the price-vs-performance view for how each tier scores per dollar.

Standard paid-tier text rates are shown. Cached input appears only where Google publishes an exact rate. Batch input and output are Google's documented 50%-off rates; context-cache storage and grounding charges are separate. Long-context surcharges, including Gemini 3.1 Pro at $4/$18 above 200K tokens, are not included in the table or calculator.

How Google Gemini token pricing works
Every Gemini generation ships the same three-tier ladder. Pro is the frontier tier: Gemini 3.1 Pro lists at $2/$12 per million tokens. Flash is the workhorse: Gemini 3.8 Flash costs $0.75/$3.75, 3.7 Flash $0.75/$3.75 and 3.6 Flash $0.75/$3.75 at introductory rates that run through December 31, 2026 and double on January 1, 2027. Gemini 3.5 Flash has no introductory rate and costs $1.50/$9.00. Flash-Lite targets high-volume work: Gemini 3.5 Flash-Lite costs $0.30/$2.50, while the still-listed Gemini 2.5 Flash-Lite is the absolute floor at $0.10/$0.40.
The detail that surprises budgets is long-context pricing. Google's pricing page lists the Pro rates for prompts up to 200K tokens, rising to $4/$18 above that on Gemini 3.1 Pro; Gemini 2.5 Pro jumps from $1.25/$10.00 to $2.50/$15 past 200K. If you routinely stuff the 1M-token window, model the higher rate — the estimator above uses standard-tier prices.
Gemini vs OpenAI and Claude pricing
At the flagship tier Google undercuts both rivals on paper. On input, Gemini 3.1 Pro ($2) costs half as much as GPT-5.6 Sol ($4) and about 60% less than Claude Opus 4.8 ($5). On output ($12), it costs about 40% less than Sol ($20) and about 52% less than Opus 4.8 ($25). The tighter fight is the mid-tier: Gemini 3.8 Flash ($0.75/$3.75) sits between GPT-5.6 Terra ($2/$12) and GPT-5.6 Luna ($0.20/$1.20) on both rates, and below Claude Sonnet 5 ($2/$10). At the floor, Gemini 2.5 Flash-Lite ($0.10/$0.40) undercuts Haiku 4.5 ($1/$5): its input costs about 10x less than Haiku's, and its output costs about 13x less than Haiku's.
Google, OpenAI, and Anthropic all publish lower asynchronous Batch rates, but long-context and cache storage rules differ by model. Compare the full tables at OpenAI API pricing and Claude API pricing, or run head-to-heads on the compare hub.
Which Gemini tier should you pick?
Start with Gemini 3.8 Flash ($0.75/$3.75), Google's newest Flash model, as the general-purpose tier. Before escalating to Gemini 3.1 Pro ($2/$12) for hard reasoning, agentic coding, or work where quality failures cost more than tokens, compare the two model profiles: under the 200K surcharge line, Pro input costs about 2.7x as much as 3.8 Flash input.
Route the boring volume — classification, extraction, tagging, short summaries — to Gemini 3.5 Flash-Lite ($0.30/$2.50) when its newer model behavior matters. Gemini 2.5 Flash-Lite ($0.10/$0.40) is cheaper for workloads that tolerate the older tier. The previous-generation Gemini 3 Flash ($0.50/$3.00) and 2.5 Flash ($0.30/$2.50) remain priced for pinned workloads. A three-way routing split typically lands the blended rate well below running everything on one tier — model yours with the LLM API pricing calculator.
If the choice is between two Gemini tiers, Gemini 3.8 Flash compared with Gemini 3.1 Pro sets the benchmark difference beside the price difference.
Gemini API pricing is separate from Google AI plans
Gemini API usage is metered through a Google AI Studio or Google Cloud billing account. Google AI consumer subscriptions are monthly plans for the Gemini app and bundled products; buying a consumer plan does not create a pool of Gemini API tokens.
Use this page for applications billed by input, cached-input, and output tokens. Vertex AI can expose the same model families with separate platform, regional, and provisioned-throughput considerations. Consumer plan comparisons belong to the ChatGPT vs Gemini guide.
Gemini API pricing FAQ
How much does the Gemini API cost?
Gemini API pricing runs from $0.10/$0.40 per million input/output tokens (Gemini 2.5 Flash-Lite) through $0.30/$2.50 (Gemini 3.5 Flash-Lite) and $0.75/$3.75 (Gemini 3.8 Flash, introductory through December 31, 2026) to $2/$12 for Gemini 3.1 Pro — with Pro rates rising to $4/$18 on prompts above 200K tokens. The full table above lists every current and legacy Google model.
Is the Gemini API free?
Google offers a rate-limited free tier of the Gemini API through AI Studio, which is enough for prototyping but not production traffic. Paid usage bills per million tokens at the rates above — the cheapest listed paid path is Gemini 2.5 Flash-Lite at $0.10/$0.40. Google's open-weight Gemma models can also be self-hosted at no per-token cost.
What is Google Gemini API pricing per 1M tokens?
Google bills the Gemini API per million tokens with separate input and output rates: Gemini 3.1 Pro at $2 input / $12 output, Gemini 3.8 Flash at $0.75/$3.75 (introductory through December 31, 2026), Gemini 3.5 Flash-Lite at $0.30/$2.50, and Gemini 2.5 Flash-Lite at $0.10/$0.40. Pro tiers carry a documented long-context surcharge above 200K tokens ($4/$18 on 3.1 Pro).
How does Gemini pricing compare to GPT and Claude?
Gemini 3.1 Pro ($2/$12) costs half as much as GPT-5.6 Sol ($4/$20) on input and about 40% less than Sol on output, and it costs less than Claude Opus 4.8 ($5/$25) on both rates. Mid-tier, Gemini 3.8 Flash ($0.75/$3.75) sits between GPT-5.6 Luna and Terra, and at the floor Gemini 2.5 Flash-Lite ($0.10/$0.40) costs less than Claude Haiku 4.5 ($1/$5) on both rates.
