Google has unveiled the successor to its language model PaLM (Pathways Language Model) during its Google I/O conference.
PaLM 2 is intended to power many of the AI-based features found in Google’s services. Google is already said to have begun using PaLM 2 in several of its services, including the chatbot Bard.
Google has not yet disclosed exactly how many parameters are in PaLM 2. The largest version of its predecessor PaLM had 540 billion parameters. PaLM 2 will be offered in four different sizes (Gecko, Otter, Bison, and Unicorn), which will be offered to Google’s customers who want to use the language model to build their own AI applications.
PaLM has also been developed into models that are specific to different areas. For example, there is Med-PaLM 2, which is specially developed for the healthcare industry, and Sec-PaLM, which is focused on security.
