Frequently Asked Questions about Gemini 3.5 Live Translate
How much does the Gemini 3.5 Live Translate API cost per 1M tokens?+
Gemini 3.5 Live Translate by Google is priced at $5 per 1M input tokens and $20 per 1M output tokens. With prompt caching enabled, cached input tokens cost $1 per 1M tokens, and asynchronous Batch API requests receive a 20% discount.
Should I use a $20/month subscription or the Gemini 3.5 Live Translate 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 Live Translate's context window?+
Gemini 3.5 Live Translate features a 131K tokens context window, which equals approximately 98,304 English words or ~262 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 16,384 tokens.
Can I run Gemini 3.5 Live Translate locally on my own GPU (Open Weights)?+
No, Gemini 3.5 Live Translate 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 Live Translate 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 Live Translate perform on coding and reasoning benchmarks?+
Gemini 3.5 Live Translate achieves a composite Intelligence Index of 84/100, scoring N/A% on SWE-bench Verified, N/A% on GPQA Diamond, N/A% on MMLU-Pro, and 1420 pts on Chatbot Arena Elo.
What is Gemini 3.5 Live Translate best used for?+
Gemini 3.5 Live Translate is best suited for: 专注于超自然语音合成、实时音频理解与低延迟语音交互的任务、企业级 RAG 检索增强生成、自动化智能体工作流与高可靠 API 集成。. Assessment: Gemini 3.5 Live Translate 凭借 84/100 的智能得分、131K 上下文容量与 130 Token/秒的响应速度，在 Google 模型矩阵中提供了极佳的性能与成本平衡。

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to Gemini 3.5 Live Translate:
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.
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.
An open standard created by Anthropic that allows AI applications and agents to connect seamlessly to local filesystems, development environments, and third-party APIs via standardized server interfaces.
A cost and latency optimization where inference providers store pre-computed attention states for repeated prompt prefixes. Reusing cached tokens typically slashes API input costs by 50% to 90% and cuts TTFT substantially.
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.
