Gemini 2.5 Flash

by Google

Gemini 2.5 Flash is Google's speed-optimized multimodal model, balancing strong reasoning with low latency across text, image, video, and audio input. It handles multimodal queries efficiently while keeping the depth needed for harder tasks, and it includes a thinking capability for more complex reasoning. The model supports function calling and structured output for programmatic control, and its 1M token context window accommodates long documents, extended conversations, and substantial multimodal interactions. It fits a wide range of work, from agentic systems and interactive video analysis to structured data extraction.
