Gemini 2.5 Flash

Balanced speed and reasoning with thinking support; 20-30% token efficiency improvement over 2.0; optimized for high-volume intelligent workloads.

Gemini 2.5 Flash launched March 2025 as the updated workhorse model combining 2.0 Flash's exceptional speed with 2.5 Pro's enhanced reasoning capabilities. The model demonstrates 20-30% improved token efficiency compared to 2.0 Flash, reducing both processing costs and latency while improving output quality. 2.5 Flash supports optional thinking mode (experimental) enabling transparent reasoning chains for complex tasks. The model excels at large-scale intelligent chatbot operations, multimodal content analysis, coding assistance, and general-purpose tasks where both speed and quality matter. Benchmarks show improvements across reasoning, multimodality, coding, and long-context tasks. Supports 1-million-token context, native audio I/O, and tool use. Knowledge cutoff: January 2025. Generally available June 2025 and becomes the new default in the Gemini app.
