Frequently Asked Questions about Gemini 3.5 Flash-Lite
How much does the Gemini 3.5 Flash-Lite API cost per 1M tokens?+
Gemini 3.5 Flash-Lite by Google is priced at $0.4 per 1M input tokens and $2 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.1 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the Gemini 3.5 Flash-Lite pay-as-you-go API?+
A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.
How many words and pages fit in Gemini 3.5 Flash-Lite's context window?+
Gemini 3.5 Flash-Lite features a 1.0M tokens context window, which equals approximately 786,432 English words or ~2,097 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 32,768 tokens.
Can I run Gemini 3.5 Flash-Lite locally on my own GPU (Open Weights)?+
No, Gemini 3.5 Flash-Lite is a proprietary closed-weights model hosted by Google. It cannot be downloaded for local GPU execution and must be accessed via Google's official API or cloud platform.
Does Google train on data sent to the Gemini 3.5 Flash-Lite API, and is commercial use allowed?+
API payloads are excluded from model training by default. License tier: Proprietary Commercial API (Google Terms). Full commercial ownership of generated outputs. Supported deployment channels include: Google AI Studio API, Google Cloud Vertex AI.
How does Gemini 3.5 Flash-Lite perform on coding and reasoning benchmarks?+
Gemini 3.5 Flash-Lite achieves a composite Intelligence Index of 69/100, scoring N/A% on SWE-bench Verified, N/A% on GPQA Diamond, 81.2% on MMLU-Pro, and 1375 pts on Chatbot Arena Elo.
What is Gemini 3.5 Flash-Lite best used for?+
Gemini 3.5 Flash-Lite is best suited for: 초저지연 실시간 대화, 고속 라우팅 및 대규모 트래픽 처리, 엔터프라이즈 RAG 지식베이스 및 대규모 프로덕션 API 연동에 최적.. Assessment: 지능 지수 69/100점, 1.0M 컨텍스트, 초당 240 토큰의 속도를 갖춘 Gemini 3.5 Flash-Lite 모델은 Google 생태계에서 성능과 경제성을 모두 만족시키는 검증된 선택입니다.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to Gemini 3.5 Flash-Lite:
The basic unit of text that a language model processes, typically representing about 3 to 4 English characters or roughly 0.75 words. For example, the sentence "Artificial intelligence is fast" breaks down into about 5 tokens.
A standardized evaluation suite used to objectively measure and rank an AI model's capabilities across specific tasks — such as SWE-bench Verified for software engineering, AIME for competitive math, or MMLU for general knowledge.
The maximum number of tokens a model can consider at once — both the input it reads and the output it writes. A 1,000,000-token context window can hold roughly 750,000 English words in a single request.
An AI model trained via reinforcement learning to spend dynamic compute thinking through complex logic, math, and architectural problems before outputting a solution. Examples include OpenAI o1, o3, and DeepSeek R1.
A step-by-step reasoning technique where an AI model generates intermediate problem-solving thoughts before arriving at a final answer. Native reasoning models like OpenAI o3 and DeepSeek R1 use CoT to solve complex math and coding challenges.
The ability of a language model to recognize when an external capability is needed and output structured JSON arguments to invoke external APIs, databases, or terminal commands. The runtime executes the tool and passes results back to the model.
Benchmark scores, token prices, and rate limits evolve rapidly as AI labs release model updates. Always verify current specifications and pricing on the official provider documentation.
