What a typical workload costs
An app that sends 1,000 requests a day, each with a 2,000-token prompt and a 500-token answer, uses 60M input and 15M output tokens in 30 days. If 1,500 of those prompt tokens are the same system prompt and context every time, prompt caching bills 45M of them at the cached rate (cache writes and storage not included). Batch is the same traffic sent as asynchronous batch jobs.

| Gemini 4 Argon | $270 | $185 | $135 |
| Gemini 3.8 Flash | $101 | $70.88 | $50.63 |

FAQ
How much does the Gemini API cost?+
Google charges per token. On 2026-11-02 its official pricing page listed, per 1M tokens: Gemini 4 Argon $2 input / $10 output, Gemini 3.8 Flash $0.75 input / $3.75 output, Gemini 3.5 Flash-Lite $0.30 input / $2.50 output, Gemini 3.1 Flash-Lite $0.25 input / $1.50 output and Gemini 3.1 Pro Preview $2 input / $12 output, plus 2 more in the table above.
What is the cheapest Google model?+
Gemini 3.1 Flash-Lite: $0.25 per 1M input tokens and $1.50 per 1M output tokens. For the example workload on this page (30,000 requests a month) that is about $37.50 a month, against $300 on Gemini 3.1 Pro Preview, the most expensive Google model here.
Does Google have prompt caching or cheaper cached input?+
Yes. Cached input tokens cost $0.10 on Gemini 4 Argon (95% less than regular input), $0.075 on Gemini 3.8 Flash (90% less than regular input), $0.03 on Gemini 3.5 Flash-Lite (90% less than regular input) and $0.025 on Gemini 3.1 Flash-Lite (90% less than regular input). Google also bills cache storage by the hour (for example $1.00 per 1M tokens per hour on the Flash-Lite models).
Does Google offer a batch discount?+
Yes: 50% off for asynchronous batch requests on Gemini 4 Argon, Gemini 3.8 Flash, Gemini 3.5 Flash-Lite, Gemini 3.1 Flash-Lite and Gemini 3.1 Pro Preview. Batch requests are processed in the background instead of answered right away, so they suit evals, backfills and bulk summaries rather than chat.
How does Gemini 4 Argon compare on price with other AI APIs?+
At $2 input / $10 output per 1M tokens, the closest-priced models from other providers are Claude Sonnet 5.5 (Anthropic, $2 / $10) and GPT-6.1 Sol (OpenAI, $2 / $10). Price per token isn't the whole bill: compare quality on your own prompts, and how many tokens each model uses for the same task.
How current are these prices?+
They were copied from Google's official pricing page on 2026-11-02, and the month in this page's title is that check date. Prices change often, so confirm on the official page before you commit to a budget.
