Gemini 3 Flash API
Gemini 3 Flash is a language model from google, available on Routeriva under the model ID gemini-3-flash. You call it with the same sk- key you use for every other model — no separate google account is needed.
On Routeriva it costs $0.13 per 1M input tokens and $0.75 per 1M output tokens, compared with the official list price of $0.50 / $3.00 — about 75% less. Prices shown are the lowest across the routes that serve this model; your key is charged at its own route's price.
The context window is 1,000,000 tokens, so you can send long documents, codebases or chat histories in a single request.
Gemini 3 Flash is reachable both through the OpenAI-compatible /v1/chat/completions endpoint and the native Gemini generateContent endpoint, so the official Google SDKs work by changing only the base URL.
Google's speed-first multimodal model — low-latency responses for chat, extraction and high-volume pipelines.
