Model overview
gemini-2.5-flash represents Google's latest hybrid "thinking" AI model designed to balance reasoning capabilities with speed and cost-efficiency. This model introduces a unique dynamic thinking feature that adjusts computational resources based on query complexity, setting it apart from traditional large language models. Unlike simpler models in the Gemini family such as gemma-2-2b-it or gemma-2-2b, this flash variant incorporates sophisticated reasoning mechanisms while maintaining rapid response times. The model builds on the foundation of previous Gemini research detailed in papers about Gemini 2.5's advanced reasoning capabilities and multimodal understanding.
Model inputs and outputs
The model accepts text prompts with extensive customization options for controlling output generation and reasoning behavior. Users can fine-tune the model's thinking process through dedicated parameters, adjust sampling strategies, and set precise output limits. The system includes both static and dynamic thinking modes, allowing for flexible resource allocation based on task complexity.
Inputs
- Prompt: The main text input that defines the task or query
- System instruction: Optional guidance that shapes the model's behavior and response style
- Temperature: Controls randomness in output generation (0-2 range)
- Top P: Nucleus sampling parameter for token selection probability
- Max output tokens: Maximum length limit for generated responses (up to 65,535 tokens)
- Thinking budget: Computational resources allocated for reasoning (0-24,576)
- Dynamic thinking: Toggle for automatic thinking resource adjustment based on complexity
Outputs
- Generated text: Array of text strings that can be concatenated into a complete response
Capabilities
This model excels at complex reasoning...
