Gemini 2.5 Flash

Gemini 2.5 Flash is a new lightweight AI model from Google. It offers better reasoning skills while keeping speed and cost in mind. This model is now available in preview through the Gemini API, Google AI Studio, and Vertex AI. It is also accessible in the Gemini app. Gemini 2.5 Flash is the first fully hybrid reasoning model. This means developers can turn thinking on or off and set a thinking budget to balance quality, cost, and speed.

Benefits
\nGemini 2.5 Flash builds on the foundation of Gemini 2.0 Flash, delivering a major upgrade in reasoning skills. The model can perform a thinking process to better understand prompts, break down complex tasks, and plan responses. This makes it particularly effective for tasks that require multi-step reasoning, such as solving math problems or analyzing research questions. The model automatically decides how much to think based on the perceived task complexity. However, developers can also set a specific token budget for the thinking phase.

The thinking budget can range from 0 to 24,576 tokens for Gemini 2.5 Flash. Setting the thinking budget to 0 allows developers to maintain the speed and cost of 2.0 Flash while still improving performance. The model''s reasoning skills are demonstrated through various examples, including prompts that require low, medium, and high reasoning.

Gemini 2.5 Flash is designed to be cost-efficient. Pricing varies based on the thinking budget. The model''s performance has been benchmarked against other AI models, showing strong results in areas like math, science, reasoning, and code generation. It is positioned as a Pareto frontier model, offering the best possible trade-off between speed, cost, and quality.

Use Cases
\nGemini 2.5 Flash is particularly useful for enterprise applications that require deep reasoning and complex problem-solving. For example, it can be used for tasks that demand advanced reasoning and coding expertise. It is optimized for low latency and cost-efficiency. Both models are available on Vertex AI, Google''s comprehensive platform for building and managing AI applications and agents.

Google is also introducing new features on Vertex AI to enhance the performance and flexibility of Gemini models. These include supervised tuning for data specialization and context caching for efficient long-context processing. These features will help businesses tailor Gemini models to their specific needs and optimize their AI applications.

Additional Information
\nGemini 2.5 Flash is part of a growing family of Gemini models, which includes Gemini 2.5 Pro, Gemini 1.5 Pro, Gemini 1.5 Flash, Gemini 2.0 Flash, and Gemini 2.0 Flash-Lite. These models provide developers with a range of options for building AI applications and agents. Google continues to innovate in this space, with plans to introduce more features and improvements in the future.

Gemini 2.5 Flash is available in the Gemini app, where users can experiment with the model''s capabilities. The app also includes new features like Canvas, a collaborative space for refining text and code. Developers are encouraged to explore the model''s potential and provide feedback to help shape its future development.
