## RésuméDe400mots

Google announced the **stable general availability** of Gemini 2.5 Flash-Lite, marking a significant advance in the Gemini 2.5 model family. Positioned as **the fastest and most cost-efficient model**, priced at **$0.10 per million input tokens and $0.40 per million output tokens**, Flash-Lite is designed to deliver exceptional intelligence per dollar. This release builds on the success of 2.5 Pro and 2.5 Flash, completing the 2.5 model lineup ready for large-scale production use.

**Performance and latency optimization**

Gemini 2.5 Flash-Lite is particularly optimized for **latency-sensitive applications** such as translation and classification, where speed and cost efficiency take priority without compromising quality. It shows **lower latency** than its predecessors, 2.0 Flash-Lite and 2.0 Flash, across a wide range of prompts. In addition, Google has **cut audio input pricing by 40%** since the preview launch, reinforcing its financial accessibility.

**Benchmark quality**

Despite its cost-efficient positioning, the model demonstrates **high quality across various benchmarks**, including code, math, science, reasoning, and multimodal understanding, **outperforming 2.0 Flash-Lite**. Developers building with 2.5 Flash-Lite have access to a robust feature set, including a **1 million token context window**, controllable thinking budgets, and native tool support. These tools include **Grounding with Google Search, Code Execution, and URL Context**, enabling more sophisticated and integrated AI applications.

**Validated real-world applications**

Practical applications of Gemini 2.5 Flash-Lite are already visible across several successful deployments. **Satlyt** leverages its speed to achieve a **45% reduction in latency** for critical onboard diagnostics and a **30% drop in power consumption** for its decentralized space computing platform. **HeyGen** relies on the model to automate video planning, optimize content, and translate videos into **more than 180 languages**, enabling global and personalized user experiences. **DocsHound** turns product demos into comprehensive documentation by quickly processing long videos and extracting thousands of screenshots. **Evertune** benefits from Flash-Lite's speed to rapidly scan and synthesize large volumes of model outputs, providing dynamic and timely analysis for brands monitoring their representation across AI models.

**Accessibility and deployment**

Developers can start using the **stable version** of Gemini 2.5 Flash-Lite by specifying **"gemini-2.5-flash-lite"** in their code, with the preview alias being removed on **August 25**. The model is available in **Google AI Studio and Vertex AI**, inviting developers to explore its capabilities for building innovative AI solutions. This strategic positioning of Flash-Lite as the go-to choice for cost-efficient, latency-sensitive applications illustrates Google's commitment to offering a multi-tier model lineup addressing developers' varied needs, from ultra-fast inference to deep reasoning, while maintaining competitive pricing to democratize access to advanced AI.
