Google AI Palm 2 is a next-generation large language model (LLM) that excels in advanced reasoning tasks such as code math, classification, question answering, translation, and natural language generation. It is built on the foundation of responsible AI, grounded in rigorous evaluation of potential harms and biases, and evaluated for downstream uses in research and in-product applications. Palm 2 is pre-trained on parallel multilingual text and a diverse pre-training mixture of hundreds of human programming languages, mathematical equations, scientific papers, web pages, and more. It also incorporates compute-optimal scaling, improved dataset mixture, and updated model architecture to achieve state-of-the-art results in reasoning benchmarks, multilingual translation tasks, and toxicity classification capabilities. Palm 2 powers generative AI features and tools like the Bard Palm API to supercharge collaboration, productivity, and imagination. It also provides resources for developers to learn and experiment with generative AI using the Palm API.
