Google 推出 Gemini 3.5 Flash-Lite，面向高吞吐任务优化

Gemini API Gemini API # Gemini 3.5 Flash-Lite Gemini 3.5 Flash-Lite is a low-latency, cost-effective multimodal model optimized for high-throughput, low-cost execution for subagent tasks and document parsing. The model supports text, image, video, audio, and PDF inputs, and is designed for high-volume agentic workflows, simple data extraction, and applications where latency and API cost are the primary constraints. ## Documentation Visit the Latest model page for full coverage of features and capabilities. ## gemini-3.5-flash-lite

## Faster and lighter, too The efficiency result is the surprising part. Even against the prior "lite" model, Gemini 3.5 Flash Lite is the leaner one on this workload: it reaches its answers in roughly a quarter of the time (about 27 seconds per task on average vs. ~99), using about half the tokens and a third of the model and tool calls. Rather than trading quality for speed, the earlier model appears to work harder — more retrieval and reasoning turns — and still arrives at less accurate answers. For enterprise workloads at scale, Gemini 3.5 Flash Lite offers both higher accuracy and a lighter operational footprint. ## Get started [...] Sorting by type of work rather than industry sharpens the picture: Gemini 3.5 Flash Lite leads across all four modes of analytical work, and its edge grows with difficulty. It's strongest on report drafting (64% vs 46%) and expert review (62% vs 51%), and its widest margin comes on data analysis — turning imperfect source data into a number you can

3.5 Flash-Lite is the fastest model in the 3.5 series. As measured by Artificial Analysis, it runs at 350 output tokens/s. Priced at $0.3/1M input tokens and $2.5/1M output tokens and with significantly better quality than 3.1 Flash-Lite, 3.5 Flash-Lite offers a strong price-to-performance ratio for developers and customers running high throughput production traffic. 3.5 Flash-Lite executes high volume tasks at a lower latency than 3.5 Flash. [...] 3.5 Flash-Lite enables efficient scaling for agentic systems. Across thinking levels, the model significantly outperforms 3.1 Flash-Lite. Depending on the workload, developers can configure the model to prioritize low-latency, low-cost execution for high-volume tasks with the minimal and low thinking levels, or engage higher thinking levels to process multi-step subagent workloads. The model now also has computer use as a built-in tool to reliably support these agentic tasks across surfaces. It’s a significant step up in coding and agentic

### Gemini 3.5 Flash Flash models in Google’s Gemini family are built for throughput. They run faster, cost less per token, and are optimized for tasks where you need a high volume of responses — summarization, classification, structured extraction, customer-facing chat, and similar workloads. Gemini 3.5 Flash continues this tradition with a key upgrade: it generates roughly 2x more output tokens per second than Gemini 3.1 Pro while maintaining competitive accuracy on a wide range of tasks. That speed advantage is significant in production environments where response latency directly affects user experience. Key specs: [...] ## Key Takeaways Gemini 3.5 Flash generates 2x more tokens per second than Pro and costs 4–8x less — for high-volume workloads, that math is hard to ignore. Flash is competitive with Pro on coding, summarization, classification, instruction-following, and most structured tasks. Pro maintains a real edge in multi-step reasoning, long-document coherence, ambig
