Through YepAPI you access Gemini 3 Flash with a single OpenAI-compatible API key. That key also reaches other models and YepAPI's SEO, SERP, and web-scraping endpoints, so you can scrape, analyze, and summarize in one place.

What is Gemini 3 Flash?

Gemini 3 Flash is the next-generation entry in Google's Flash family, designed for speed and efficiency with a meaningful capability jump over Gemini 2.5 Flash. It pairs low latency with a 1,000,000-token context window, so it can read entire codebases, lengthy reports, or large document sets in one pass while still responding quickly. Output is capped at 8,192 tokens per response. Positioned for price-to-performance, it costs $0.70 per 1M input and $4.20 per 1M output tokens, making it a practical workhorse for production apps that need both scale and quality.

Build with Gemini 3 Flash via YepAPI

Send requests to the OpenAI-compatible /v1/ai/chat endpoint using your YepAPI key. The standard Chat Completions schema means you can switch to Gemini 3 Flash by changing only the base URL and model name in your existing SDK. Use it for chatbots, retrieval-augmented apps, and summarization over very long inputs. One key also covers other models plus SEO, SERP, and scraping endpoints, so you can fetch web data and feed it straight into Gemini 3 Flash's 1M-token window.

Gemini 3 Flash API pricing — $0.70 / $4.20 per 1M tokens

Gemini 3 Flash costs $0.70 per 1M input tokens and $4.20 per 1M output tokens. With a 1M-token context, you can feed large documents affordably, and the low input rate makes long-context summarization and analysis economical at scale. Billing is per token, so you pay only for the data you process, keeping high-volume Flash workloads cost-effective.

Gemini 3 Flash for long-context summarization

The model excels where huge inputs meet a need for speed: summarizing long reports, analyzing entire repositories, processing transcripts, or powering RAG systems with very large retrieved contexts.

The competitive input price makes it economical to run these long-context jobs continuously in production.
