Gemini 1.5 ProvsGemini 1.5 Flash

Gemini 1.5 Pro is Google DeepMind's flagship multimodal model featuring an industry-leading 1 million token context window, capable of processing entire codebases, books, or hours of video in a single prompt. It demonstrates exceptional performance on long-context reasoning tasks, multimodal understanding across text, images, audio, and video, and complex coding challenges. The massive context window opens entirely new use cases that were previously impossible with shorter-context models.

Gemini 1.5 Flash is Google DeepMind's speed-optimized model that retains the groundbreaking 1 million token context window of Gemini 1.5 Pro while offering dramatically faster inference and lower costs. It uses a novel distillation process to compress the capabilities of the larger Pro model into a lighter architecture. Flash is designed for high-volume production workloads where cost efficiency and speed are critical, while still maintaining strong multimodal understanding.
