PaLM

PaLM (Pathways Language Model) is Google AI's 540-billion-parameter foundation model, succeeded by PaLM 2 for state-of-the-art multilingual, reasoning, and coding performance.

PaLM, the Pathways Language Model, was Google AI's breakthrough 540-billion-parameter dense decoder-only transformer model, trained using the efficient Pathways system. Its successor, PaLM 2, significantly advanced its capabilities: it was trained on over 100 languages, boosting multilingual understanding and translation to a 'mastery' level. PaLM 2 also demonstrated improved logic, common sense reasoning, and specialized code generation (e.g., Prolog, Verilog). This model family is versatile, offered in four sizes—Gecko (mobile-optimized), Otter, Bison, and Unicorn—allowing for deployment across a wide range of products and enterprise use cases via Vertex AI.
