Exploring Cutting-Edge LLMs with Vertex AI and PaLM 2
Maybe Chapter 7, The Generative AI Revolution with ChatGPT, made us think that OpenAI ChatGPT ended the tremendous progression of Large Language Models (LLMs) and Generative AI. Perhaps the incredible tools, such as GitHub Copilot, GPT-4, and OpenAI’s embedding models, stunned us into believing we had reached a limit.
Then, on May 23, 2023, Google released the PaLM 2 Technical Report, built on the earlier PaLM and Pathways papers. The content of these papers is mind-blowing! The architecture of PaLM improved both software and hardware performances with ingenious innovations.
We will begin the chapter by examining Pathways to understand PaLM. We will continue and look at the main features of PaLM (which stands for Pathways Language Model), a decoder-only, densely activated, and autoregressive model transformer model with 540 billion parameters trained on Google’s Pathways system. PaLM was trained on 780 billion...
