Gemini 3.1 Flash-Lite vs GPT-5 Nano Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Google / Gemini 3.1 Flash-Lite
proDescription
Google's most cost-efficient model, and a surprisingly complete one for its tier. Gemini 3.1 Flash-Lite reads text, images, video, audio, and PDFs, holds a million tokens of context, and can ground its answers in live search. Google says it beats the previous Flash-Lite generation significantly on quality, reasoning, translation, and factuality. Built for high volume and low latency. Still a preview release.
OpenAI / GPT-5 Nano
lightDescription
OpenAI's smallest and cheapest GPT-5 model, built for speed above all. GPT-5 Nano is made for summarisation, classification, and other well-defined tasks that run at high volume. It reads text and images, with adjustable reasoning effort. Reasoning depth is shallow by design and its knowledge is dated. The trade is cost: it is among the cheapest models in the catalog.

Why Use Gemini 3.1 Flash-Lite and GPT-5 Nano?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
Google / Gemini 3.1 Flash-Lite
proFast Codebase Exploration
Developers Google quotes describe it exploring codebases in a fraction of the time larger models take, while still following instructions closely. Strong on tool calling, which is what makes agentic coding work.
Adjustable Thinking Levels
Thinking runs at minimal, low, medium, or high, so you set how much reasoning each request gets. That control is the whole point in a model built for cost-sensitive, high-volume traffic.
Million-Token Context
A one-million-token input window, matching Google's flagship tier. Load a full repository or a long document set and work across all of it in one pass without chunking the input.
Translation And Instruction Following
Google names translation and instruction following as areas of targeted improvement, and positions it as a reliable path for instruction-heavy chatbot workflows. Output caps at 64,000 tokens per response.
Search As A Tool
Its knowledge cutoff is January 2025, and Google's own guidance is to use the Search Grounding tool for anything more recent. Code execution and structured output are supported too.
Text Image Video Audio
Accepts text, images, video, audio, and PDFs. Google specifically improved audio input quality for speech recognition tasks. Output is text only. An unusually wide input range for a budget model.
OpenAI / GPT-5 Nano
lightCoding Sub-Tasks
Suited to small, well-scoped coding jobs and to acting as a fast sub-agent inside a larger system, rather than tackling whole problems. Reasoning depth is limited, so keep the scope tight.
Adjustable Reasoning Effort
Reasoning effort runs from minimal through low, medium, and high. Even at higher effort it is a shallow reasoner by design, so it suits speed-sensitive work rather than hard multi-step problems.
Room For Long Documents
A large context window, enough to summarise long reports or classify big batches of text in a single pass without splitting the input into separate requests.
Summarisation And Classification
OpenAI names summarisation and classification as its core uses. Built to process high volumes of text quickly and cheaply rather than to produce polished long-form writing.
Analysis On Older Knowledge
Its training data is dated by current standards, so it is fine for processing text you supply but weaker on recent events, which need live sources rather than the model's own knowledge.
Text And Image Input
Reads text and images, so you can send screenshots or scanned pages alongside your prompt. Output is text only. OpenAI states audio and video are not supported.
