PaLM 2
PaLM 2 is Google's next-generation large language model, introduced at I/O 2023.
What is PaLM 2?
PaLM 2 is Google's next-generation large language model, introduced at I/O 2023.It delivers significant improvements in multilingual understanding, complex logical reasoning, and code generation, offering developers and enterprises a more efficient and capable AI foundation than its predecessors.
Trained on text spanning over 100 languages, PaLM 2 excels at handling nuanced semantics, including idioms, poems, and riddles, achieving 'mastery' level performance on advanced language proficiency exams.It also demonstrates enhanced capabilities in processing mathematical expressions, common sense reasoning, and scientific literature.
The model comes in four sizes—Gecko, Otter, Bison, and Unicorn—balancing speed and performance.The lightweight Gecko variant can even run offline on mobile devices, while larger variants handle complex cloud-based tasks.PaLM 2 currently powers over 25 Google products, including Bard, Workspace features, and the specialized Med-PaLM 2 for healthcare.
