Google: Gemini 3.1 Flash Lite
🇺🇸 Google · Gemini 3.1
Overview
Google: Gemini 3.1 Flash Lite is a large language model API from Google, part of its Gemini 3.1 model family. Priced at $0.250 per million input tokens and $1.50 per million output tokens, it occupies the mid-range, balancing capability against running cost. Output tokens cost about 6× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. An exceptionally large 1.05M-token context window (≈1,573 pages of text) means entire repositories or document collections can be processed without chunking. Beyond plain text it also accepts Image, Video, File, Audio input, so it can be applied to multimodal tasks rather than text alone. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
