Tips to reduce cost

  • →Use prompt caching to reuse repeated system prompts
  • →Trim whitespace and reduce verbose instructions
  • →Use a smaller model for classification or routing tasks
  • →Batch async requests to get 50% discount (OpenAI/Anthropic)
  • →Cache identical requests at the application layer

About Gemini 3 Pro

Gemini 3 Pro is a premium large language model from google, priced at $3.5/1M input tokens and $14/1M output tokens. It is priced above the market average and best suited for production reasoning at scale. The 1M context window makes it suitable for very long documents, large codebases, and book-length inputs.

For most production workloads, the cost breakdown is dominated by input tokens (system prompts, context, retrieved documents) rather than output. At this price point, Gemini 3 Pro is positioned for use cases where quality justifies the premium over cheaper alternatives.

Gemini 3 Pro supports prompt caching at $0.875/1M — a 75% discount on repeated input tokens. For applications with a fixed system prompt or repeated document context (RAG, chatbots, agents), enabling caching is the single highest-leverage cost optimization available.

Frequently Asked Questions

How much does Gemini 3 Pro cost per 1,000 tokens?
Gemini 3 Pro costs $0.0035 per 1,000 input tokens and $0.0140 per 1,000 output tokens.
What is Gemini 3 Pro's context window?
Gemini 3 Pro supports a context window of 1M tokens, which is suitable for very long documents, large codebases, and extended multi-turn conversations.
How does Gemini 3 Pro compare to GPT-4o on price?
Gemini 3 Pro is priced above the market average on input tokens. At $3.5/1M input vs $2.50/1M for GPT-4o, the cost difference becomes significant at scale — 10,000 requests/day with 1,000 input tokens each costs $1050/month with Gemini 3 Pro vs $750/month with GPT-4o.
Does Gemini 3 Pro support prompt caching?
Yes. Gemini 3 Pro supports prompt caching at $0.875/1M tokens — a 75% discount on repeated input. This is especially effective for RAG pipelines and chatbots with large system prompts that repeat across requests.
