Gemini 3.1 Flash Lite Preview is a Google Gemini-family model built for reasoning, coding, mathematics and general chat. It supports configurable "thinking" (reasoning effort levels) so you can trade cost and latency for accuracy on hard tasks. It accepts text, images, video, PDFs and files and audio and returns text, with a context window of up to 1.0M tokens.

Its multimodal input makes it suitable for document understanding, chart and image analysis, and workflows that mix text with images and video. With thinking enabled it is stronger on multi-step reasoning; with thinking minimal it responds quickly and cheaply.

Pricing is usage-based at $0.25/M in · $1.5/M out. Gemini 3.1 Flash Lite Preview is served through Hormouz behind an OpenAI-compatible API, with stable access from inside Iran.

Gemini 3.1 Flash Lite Preview is Google's high-efficiency model optimized for high-volume use cases. It outperforms Gemini 2.5 Flash Lite on overall quality and approaches Gemini 2.5 Flash performance across...
