Overview

Gemini 3.1 Flash Lite is Google's most affordable Gemini 3.x model — designed for high-volume, low-latency tasks where cost is the primary constraint. It keeps the full 1M token context window that defines the Gemini 3.x family, but trades some output quality and reasoning depth for the lowest input/output pricing in the lineup ($0.25/$1.50 per 1M tokens).

It is ideal for production workloads where each individual request is simple but volume is high: classification, summarization, content moderation, intent routing, retrieval-augmented chat, multilingual content tagging, and similar tasks. The 1M context window also makes it a strong choice for processing long documents at low cost.

Like the other Gemini 3.x models on CallMissed, it routes directly to Google AI Studio — there is no OpenRouter hop, no markup, and pricing matches Google's published rate verbatim.
