Summary
Gemini 1.5 Pro is a next-generation multimodal large language model (LLM) developed by Google DeepMind and announced by Google CEO Sundar Pichai in February 2024. It represents a significant advancement in artificial intelligence, most notably featuring a revolutionary context window that supports up to 1 million tokens, with experimental capabilities reaching up to 10 million tokens. This allows the model to process and reason across massive datasets, including hours of video, thousands of lines of code, or long-form documents. Positioned as a mid-size model that performs at a level comparable to the larger Gemini 1.0 Ultra, it is designed for greater efficiency, requiring less training compute and offering better scalability. The model is integrated into Google's ecosystem through Vertex AI and Google Workspace, serving as a key component in the broader AI boom alongside other technologies like OpenAI's Sora and Meta's Testgen.

- Introducing Gemini 1.5, Google's next-generation AI model
Last week, we rolled out our most capable model, Gemini 1.0 Ultra, and took a significant step forward in making Google products more helpful, starting with Gemini Advanced. The first Gemini 1.5 model we’re releasing for early testing is Gemini 1.5 Pro. It’s a mid-size multimodal model, optimized for scaling across a wide-range of tasks, and performs at a similar level to 1.0 Ultra, our largest model to date. As 1.5 Pro’s long context window is the first of its kind among large-scale models, we’re continuously developing new evaluations and benchmarks for testing its novel capabilities. In advance of releasing 1.5 Pro, we've taken the same approach to responsible deployment as we did for our Gemini 1.0 models, conducting extensive evaluations across areas including content safety and representational harms, and will continue to expand this testing. We’ll introduce 1.5 Pro with a standard 128,000 token context window when the model is ready for a wider release.

- Gemini 1.5 Pro
Gemini 1.5 Pro matches or outperforms Gemini 1.0 Ultra across standard benchmarks and achieves near-perfect retrieval (>99%) up to at least 10 million tokens, a significant advancement compared to other long context LLMs. As part of this release, Google is also featuring a new experimental 1 million token context window model which will be available to try out in Google AI Studio. There aren't too many details in the technical report (opens in a new tab), but it's reported that Gemini 1.5 Pro uses significantly less training compute, is more efficient to serve, and involves architecture changes that enable long-context understanding (up to 10 million tokens). the Gemini 1.5 Pro model in the Google AI Studio supports up to 1 million tokens so we are able to upload entire PDFs.
