Gemini 2.5 Flash
Google Gemini model entry for low-latency, high-volume, multimodal, and agentic workloads.
Gemini 2.5 Flash is Google’s cost-efficient multimodal model optimized for low-latency, high-volume generation tasks. With a 1,048,576-token context window and support for text, image, audio, and video inputs, it handles a broad range of production workloads from content generation to multimodal classification and real-time agent interactions.
The model excels at tasks where throughput matters — batch processing, real-time chat applications, and high-volume content pipelines. It integrates through the Google Gen AI SDK and Vertex AI, with support for function calling, structured output, and Google search grounding for retrieval-augmented generation.
For teams building Google-native applications, Gemini 2.5 Flash offers the best throughput-to-cost ratio in the Gemini lineup. It supports thinking mode for improved reasoning on complex prompts while maintaining flash-tier speed. Google released the newer Gemini 3.5 Flash in May 2026, which offers improved performance at similar latency characteristics.
