Google has recently introduced its next-generation language model, PaLM 2, which boasts of improved multilingual, reasoning, and coding capabilities. PaLM 2 is a versatile family of models that comes in four sizes - Gecko, Otter, Bison, and Unicorn. In this article, we'll delve into what PaLM 2 is all about and how it's being used to power over 25 Google products and features.


PaLM 2 is more heavily trained on multilingual text than its predecessors, spanning more than 100 languages. This has significantly improved its ability to understand, generate, and translate nuanced text, including idioms, poems, and riddles, across a wide variety of languages, which was a hard problem to solve. PaLM 2 also passes advanced language proficiency exams at the "mastery" level, making it an exceptional tool for people around the world who use different languages.


PaLM 2's wide-ranging dataset includes scientific papers and web pages that contain mathematical expressions. As a result, it demonstrates improved capabilities in logic, common sense reasoning, and mathematics. These improvements make it ideal for research applications that require logical reasoning and mathematical calculations.


PaLM 2 was pre-trained on a large quantity of publicly available source code datasets, making it an excellent tool for coders. It excels at popular programming languages like Python and JavaScript, but can also generate specialized code in languages like Prolog, Fortran, and Verilog. This makes it an ideal tool for developers who work on a wide range of projects.

A Versatile Family of Models

PaLM 2 is faster and more efficient than previous models, and it comes in a variety of sizes, which makes it easy to deploy for a wide range of use cases. Gecko, the smallest size, is so lightweight that it can work on mobile devices and is fast enough for great interactive applications on-device, even when offline. This versatility means PaLM 2 can be fine-tuned to support entire classes of products in more ways to help more people.

Powering Over 25 Google Products and Features

PaLM 2 is already powering over 25 Google products and features. Its improved multilingual capabilities are allowing Google to expand Bard to new languages, starting today. PaLM 2 is also powering Workspace features to help users write in Gmail and Google Docs, and help them organize in Google Sheets. Med-PaLM 2, trained by Google's health research teams with medical knowledge, can answer questions and summarize insights from a variety of dense medical texts. 

Advancing the Future of AI

PaLM 2 shows us the impact of highly capable models of various sizes and speeds and how versatile AI models reap real benefits for everyone. Google is committed to releasing the most helpful and responsible AI tools today while also working to create the best foundation models for the future. Google's Brain and DeepMind research teams are being brought together into a single unit to continue to accelerate progress in AI. 

Google DeepMind, backed by the computational resources of Google, will not only bring incredible new capabilities to the products users use every day but will responsibly pave the way for the next generation of AI models. Google is already working on Gemini, its next model created from the ground up to be multimodal, highly efficient at tool and API integrations, and built to enable future innovations like memory and planning.

Benefits of PaLM 2

PaLM 2 is a significant improvement over previous language models, particularly in terms of its multilingual, reasoning, and coding capabilities. Its versatility and speed make it easy to deploy in a wide range of use cases, from mobile devices to large-scale enterprise applications.

The improved multilingual capabilities of PaLM 2 are particularly noteworthy, as they allow for greater accuracy and fluency in understanding, generating, and translating text across a wide range of languages. This is especially useful for businesses and organizations with global reach, as it can help them communicate more effectively with customers and stakeholders in different parts of the world.

PaLM 2's enhanced reasoning and coding capabilities also make it an invaluable tool for scientific and technical research, as well as for software development and engineering. Its ability to understand mathematical expressions and generate code in a variety of programming languages makes it an ideal choice for developers looking to create new software or optimize existing systems.

In addition to these benefits, PaLM 2 is also faster and more efficient than previous models, which means that it can be used to power a wide range of Google products and features without compromising on performance or speed.

Applications of PaLM 2

PaLM 2 has already been used to power over 25 Google products and features, including Workspace features in Gmail, Google Docs, and Google Sheets, as well as the Bard language model and the Med-PaLM 2 medical language model.

One of the most exciting applications of PaLM 2 is in the field of healthcare, where it has already demonstrated impressive capabilities in understanding and summarizing dense medical texts. With the addition of multimodal capabilities, PaLM 2 has the potential to revolutionize the way that medical professionals diagnose and treat patients, leading to better patient outcomes and improved overall health.

PaLM 2 also has numerous applications in the field of artificial intelligence research, where it can be used to develop new and more advanced models that can perform a wide range of tasks. The creation of Gemini, Google's next-generation AI model, is a testament to the potential of PaLM 2 and its ability to drive innovation and progress in the field of AI.


PaLM 2 is a significant breakthrough in the field of natural language processing and AI, offering improved multilingual, reasoning, and coding capabilities that make it a valuable tool for businesses, researchers, and developers alike. Its versatility and speed make it easy to deploy in a wide range of use cases, and its applications in healthcare and AI research are particularly exciting.

As Google continues to push the boundaries of what is possible with AI, we can expect to see more breakthroughs like PaLM 2 in the years to come. With the addition of Gemini, Google is poised to take AI to the next level, creating models that are even more advanced, versatile, and capable than ever before.
