Gemini 1.5 is a family of frontier language models from Google, comprising the Pro, Flash, and Flash-8B variants, built on a sparse mixture-of-experts architecture. Its key feature is an extremely long context window of up to 1-2 million tokens, enabling native multimodality (text, image, audio, video) over very long inputs. At launch, Gemini 1.5 Pro achieved top scores on benchmarks such as MMLU, outperforming the predecessor Gemini 1.0 Ultra while using less compute. The models are available via Google AI Studio, the Gemini API, and Vertex AI, and are billed on a pay-per-token basis.
