On Wednesday, Google launched PaLM 2, a household of foundational language fashions similar to OpenAI’s GPT-4. At its Google I/O occasion in Mountain View, California, Google revealed that it already makes use of it to energy 25 merchandise, together with its Bard conversational AI assistant.

Options of PaLM 2
In accordance with Google, PaLM 2 helps over 100 languages and may carry out “reasoning,” code era, and multi-lingual translation. Throughout his 2023 Google I/O keynote, Google CEO Sundar Pichai stated it is available in 4 sizes: Gecko, Otter, Bison, and Unicorn. Gecko is the smallest and may reportedly run on a cell system. Other than Bard, it’s behind AI options in Docs, Sheets, and Slides.
PaLM 2 vs. GPT-4
All that’s tremendous, however how does PaLM 2 stack as much as GPT-4? Within the PaLM 2 Technical Report, it seems to beat GPT-4 in some mathematical, translation, and reasoning duties. However the actuality won’t match Google’s benchmarks. On a cursory analysis of the PaLM 2 model of Bard by Ethan Mollick, he finds that its efficiency seems worse than GPT-4 and Bing on numerous casual language checks.

PaLM 2 Parameters
The primary PaLM was notable for its huge measurement: 540 billion parameters. Parameters are numerical variables that function the discovered “data” of the mannequin. Thus, enabling it to make predictions and generate textual content primarily based on the enter it receives. Extra parameters roughly imply extra complexity, however no assure they’re used effectively. By comparability, OpenAI’s GPT-3 (from 2020) has 175 billion parameters. OpenAI has by no means disclosed the variety of parameters in GPT-4.
Lack of Transparency
In order that results in the large query: Simply how “giant” is PaLM 2 by way of parameter rely? Google doesn’t say. This has pissed off some trade specialists who typically combat for transparency in what makes AI fashions tick. That’s not the one property of it that Google has been quiet about. The corporate says PaLM 2 has been educated on “a various set of sources: net paperwork, books, code, arithmetic, and conversational information.” However doesn’t go into element about what precisely that information is.
Issues About Coaching Information
The dataset seemingly contains all kinds of copyrighted materials used with out permission and probably dangerous materials scraped from the Web.
Future Developments
And so far as LLMs go, PaLM 2 is much from the tip of the story. Within the I/O keynote, Pichai talked about {that a} newer multimodal AI mannequin referred to as “Gemini” was at present in coaching.

Our Say
In conclusion, whereas PaLM 2 could fall quick in some areas, it represents an vital milestone in growing pure language processing know-how. As we transfer nearer to the subsequent era of language fashions, it will likely be fascinating to see the way it evolves and matures and whether or not it might tackle OpenAI’s GPT-4.
