Google Announces PaLM 2, its Newest Large Language Model At I/O Developer Conference

 Google announces the launch of PaLM 2, its newest large language model (LLM). PaLM 2 will power Google’s updated Bard chat tool, the company’s competitor to OpenAI’s ChatGPT and function as the foundation model for most of the new AI features the company is announcing today.

PaLM 2 is now available to developers through Google’s PaLM API, Firebase and on Colab. It's a 540-billion parameter model built on top of Google’s latest JAX and TPU v4 infrastructure.

PaLM 2 is better at common sense reasoning, mathematics, and logic. It was trained on a large amount of math and science texts, as well as mathematical expressions. PaLM 2 can easily solve math puzzles, reason through problems, and even provide diagrams.

PaLM 2 now features improved support for writing and debugging code. The model was trained on 20 programming languages, including popular ones like JavaScript and Python, as well as Prolog, Verilog, and Fortran.

Google says PaLM 2 can excel at multilingual tasks, including more nuanced phrasing than previous models, as it was trained on a corpus that features over 100 languages. PaLM also includes other models, such as Codey for coding and debugging and Med-PaLM 2 for medical knowledge.
