Gemini 1.5 Flash (September 2024) is a speed-optimised model from Google, designed for high-throughput, cost-sensitive workloads. Its intelligence index sits at 13.8, placing it firmly in the older-generation tier, but it benefits from Google's large context architecture and reasonable MMLU-Pro performance for its class.

For businesses, it fits best in bulk content processing, summarisation, and classification tasks where speed and cost matter more than frontier reasoning. Coding and agentic use are limited by its benchmark profile, and it has been superseded by substantially stronger Google models.

Teams already in the Google ecosystem running high-volume, lower-complexity workflows may find it cost-effective, but new adopters should evaluate more recent alternatives first.
