What is PaLM 2?

PaLM 2, which is the next-generation large language model, continues to push the boundaries of machine learning and responsible AI, building upon Google’s rich history of pioneering research in these fields.

Built upon Google’s responsible AI framework, it adheres to the company’s approach to developing and implementing AI in a responsible manner. Extensive evaluations were conducted to assess its potential risks, biases, capabilities, and applicability in both research and product settings. Furthermore, it serves as the foundation for other cutting-edge models such as Med-PaLM 2 and Sec-PaLM, while also driving the development of generative AI features and tools like Bard and the PaLM API within Google.

What can it do?

PaLM 2 is a state-of-the-art language model with improved multilingual, reasoning, and coding capabilities.

Multilinguality: It has undergone extensive training on a vast corpus of multilingual text, encompassing over 100 languages. This intensive training has greatly enhanced its proficiency in comprehending, generating, and translating nuanced textual content, including idioms, poems, and riddles. Addressing this challenging task successfully demonstrates its ability to tackle complex language nuances across diverse languages, a feat that is difficult to accomplish. Additionally, It attains a “mastery” level in advanced language proficiency examinations.


Reasoning: By incorporating a diverse dataset consisting of scientific papers and web pages containing mathematical expressions, it showcases notable advancements in logic, common sense reasoning, and mathematical capabilities. This inclusion enables it to demonstrate improved proficiency in these areas.


Coding: Through pre-training on extensive publicly available source code datasets, it has acquired exceptional proficiency in coding. It demonstrates remarkable expertise in popular programming languages such as Python and JavaScript. Moreover, it showcases the ability to generate specialized code in languages like Prolog, Fortran, and Verilog, showcasing its versatility in handling diverse programming languages.


How was it built?

It stands out in tasks such as advanced reasoning, translation, and code generation due to its unique construction. It enhances its predecessor, PaLM, by integrating three distinct research advancements into large language models:

  1. Adoption of compute-optimal scaling: The concept behind compute-optimal scaling involves scaling the model size and training dataset size proportionally. This approach allows it to be smaller in size compared to PaLM, while still maintaining better overall performance, including faster inference, fewer parameters for serving, and reduced serving costs.
  2. Enhanced dataset mixture: Unlike previous language models such as PaLM, which primarily relied on English-only text for pre-training, It significantly improves its training corpus by incorporating a more diverse and multilingual dataset mixture. This updated mixture comprises hundreds of human and programming languages, mathematical equations, scientific papers, and web pages.
  3. Updated model architecture and objective: It features an enhanced architecture and was trained on a diverse range of tasks. This broader training scope enables it to acquire a deeper understanding of various aspects of language.
