PaLM 2

PaLM 2 is Google’s next-generation large language model, introduced on May 10, 2023, with significant improvements in multilingual understanding, reasoning, and code generation. Trained on text spanning over 100 languages, it can understand and generate nuanced content such as idioms and poems, and passes advanced language proficiency exams at the mastery level. Its reasoning is enhanced by training on scientific papers and mathematical expressions, enabling stronger logic, common sense reasoning, and mathematics. Pre-trained on large public source code datasets, PaLM 2 excels in languages like Python and JavaScript and can generate specialized code in Prolog, Fortran, and Verilog. It is available in four sizes—Gecko, Otter, Bison, and Unicorn—making it versatile for deployment from mobile devices to cloud services. PaLM 2 powers over 25 Google products and features, including Bard, Workspace (Gmail, Docs, Sheets), and Med-PaLM 2 for healthcare.
