PaLM 2 is a next-generation language model that excels in advanced reasoning tasks. It is pre-trained on a diverse range of text sources, including programming languages, scientific papers, and web pages. PaLM 2 incorporates compute-optimal scaling, improved dataset mixture, and an updated model architecture to achieve state-of-the-art results in reasoning benchmarks, multilingual translation tasks, and toxicity classification capabilities. It powers generative AI features and tools, such as the Bard Palm API, to enhance collaboration, productivity, and imagination. Developers can also utilize the Palm API to learn and experiment with generative AI.
