Gemini 2.5 Flash API FAQs

Everything you need to know about the product and billing.

The Gemini 2.5 Flash API is designed for extreme affordability, priced significantly lower than Pro models (often under $0.10 per 1M input tokens), making it ideal for high-volume scaling.

It is optimized for speed, delivering sub-second first-token latency in many regions. This makes it the superior choice for real-time chatbots and interactive voice agents.

Choose the Gemini 2.5 Flash API for high-frequency tasks, real-time interactions, and processing massive amounts of data where cost and speed are critical. Use Pro for complex reasoning or mathematical proofs.

Yes, it features native multimodal capabilities. You can feed video files or audio streams directly into the API context window for instant analysis and summarization.

Absolutely. Context caching is fully supported on the Gemini 2.5 Flash API, allowing you to cache large documents or system instructions to further reduce latency and input costs.

Yes, while Pro is better for complex architecture, Gemini 2.5 Flash is excellent for rapid code completion, bug detection, and refactoring tasks across large codebases.

The standard context window is 1 million tokens, allowing for the ingestion of approximately 1 hour of video or 30,000 lines of code in a single prompt.
