PaLM 2 is a large language model from Google with improved reasoning, multilingual proficiency, and natural language generation compared to its predecessor, PaLM.
Enhanced capabilities of PaLM 2 include the following:
PaLM 2 was built on top of Google's JAX and TPU v4 infrastructure. The model is available in four sizes Geckosizes—Gecko, Otter, Bison, and Unicorn, from smallest to largest. Gecko is lightweight enough to run on mobile devices. The largest model in the PaLM 2 family, is significantly smaller than the largest PaLM model but uses more training compute. Upon its release, Google announced over 25twenty-five products and features already powered by PaLM 2, including Bard, the company's chatbot, and features for Google Workspace apps like Docs, Slides, and Sheets. Other examples of PaLM 2 Google products include the following:
PaLM 2 is available through the PaLM API, which Google havehas been previewing with a small group of developers since March 2023, in; Vertex AI,; and Duet AI for Google, a generative AI collaborator.
On October 28, 2021, Google introduced Pathways, a new AI architecture for handling differentvarious tasks, across different modalities at the same time, and learning new tasks faster. Google developed Pathways to be able to train a single model to perform thousands or millions of tasks, rather than having to train a new model from scratch for each new problem. Pathway is also more efficient than previous architectures that would typically activate the entire neural network to accomplish each task, regardless of its complexity. On March 23, 2022, Google released a paper describing the architecture titled "Pathways: Asynchronous Distributed Dataflow for ML."
On April 4, 2022, Google Research revealed Pathways Language Model (PaLM), its first LLM trained with the Pathways system. A 540-billion parameter, decoder-only Transformer model, PaLM was trained across mutiplemultiple TPU v4 Pods. A day later, Google released a paper describing the new LLM titled "PaLM: Scaling Language Modeling with Pathways."
Google utilized several data cleaning and quality filtering methods, including de-duplication and the removal of sensitive, personally identifiable information.
Google evaluated the performance of three PaLM 2 variants (small, medium, and large) for a number of tasks, including the following:

PaLM 2 is a large language model (LLM) from Google introduced on May 10, 2023, at the company's I/O conference. PaLM 2 is the successor to the Pathways Language Model (PaLM) released in April 2022 as part of Google's Pathways vision (building a single highly efficient model that can generalize across domains and tasks). PaLM 2 is faster and more efficient than its predecessor, with additional capabilities in reasoning tasks, including code and math, classification and question answering, translation and multilingual proficiency, and natural language generation. These improvements are made possible due to three key LLM research advancements:
Enhanced capabilities of PaLM 2 include:
Example of PaLM 2 multilingual reasoning, understanding an idiom in the German language.

On May 10, 2023, Google CEO Sundar Pichai introduced PaLM 2 onstage at the company's I/O conference. The release of PaLM 2 was accompanied by a technical report with details on the new LLM.
PaLM 2's pre-training corpus is composed of a diverse set of sources: web documents, books, code, mathematics, and conversational data. The corpus is significantly larger and includes a higher percentage of non-English data than the one used to train PaLM. In addition to more non-English data, PaLM 2 was trained on parallel data covering hundreds of languages in the form of source and target text pairs where one side is in English. The inclusion of parallel multilingual data further improves the model’s ability to understand and generate multilingual text. It also produces an inherent ability for translation into the model, which can be useful for various tasks.
The language distribution of web documents excluding English.
Google utilized several data cleaning and quality filtering methods, including de-duplication and the removal of sensitive personally identifiable information.
Google evaluated the performance of three PaLM 2 variants (small, medium, and large) for a number of tasks including:
Evaluations include exams designed for humans and standard academic machine-learning benchmarks. Generally, the model was evaluated in a few-shot, in-context learning setting, with the model given a short prompt and, optionally, a few examples of the task. Google reports strong quality improvements across all areas.
