PaLM 2
Over the past decade, Google has been at the forefront of numerous breakthroughs in artificial intelligence (AI). Their work in foundation models has paved the way for AI-powered products that billions of people use every day. As Google continues to responsibly advance these technologies, the potential for transformational applications in healthcare and human creativity is immense.
Throughout their journey in AI development, Google has discovered that scaling up neural networks opens up a world of possibilities. Larger models have showcased surprising and delightful capabilities. However, Google’s research has also shown that size alone doesn’t guarantee success. Research creativity plays a crucial role in building exceptional models. Recent advancements in model architecture and training techniques have enabled Google to unlock multimodality, understand the significance of human feedback, and build models more efficiently than ever before. These foundational advancements empower Google to push the boundaries of AI while creating models that bring tangible benefits to people’s daily lives.
Introducing PaLM 2, Google’s Next-Generation Language Model
Building upon their previous work, Google is proud to introduce PaLM 2, their next-generation language model. PaLM 2 is a state-of-the-art language model that boasts enhanced multilingual, reasoning, and coding capabilities.
Multilinguality: PaLM 2 has undergone extensive training on multilingual text, encompassing over 100 languages. This intensive training has significantly improved its ability to understand, generate, and translate nuanced text across a wide range of languages, including idioms, poems, and riddles. Solving this complex challenge represents a significant milestone. Moreover, PaLM 2 can successfully pass advanced language proficiency exams at the “mastery” level.
Reasoning: PaLM 2’s comprehensive dataset includes scientific papers and web pages containing mathematical expressions. Consequently, the model demonstrates remarkable advancements in logic, common sense reasoning, and mathematics.
Coding: To enhance its coding capabilities, PaLM 2 was pre-trained on large quantities of publicly available source code datasets. This equips the model with exceptional proficiency in popular programming languages such as Python and JavaScript. Additionally, PaLM 2 can generate specialized code in languages like Prolog, Fortran, and Verilog.
A Versatile Family of Models
PaLM 2 not only exhibits superior capabilities but also delivers improved speed and efficiency compared to previous models. It is available in four different sizes, catering to a wide range of use cases. The four sizes, from smallest to largest, are Gecko, Otter, Bison, and Unicorn. Gecko, the smallest variant, is lightweight enough to function on mobile devices and offers excellent performance even when offline. This versatility enables PaLM 2 to be fine-tuned and applied in various domains, thereby benefiting a greater number of individuals.
Powering Google Products and Features
During the recent I/O event, Google announced that over 25 new products and features are powered by PaLM 2. This means that the latest advanced AI capabilities are being integrated directly into Google’s products, benefitting consumers, developers, and enterprises worldwide. Here are a few examples:
Multilingual Capabilities: PaLM 2’s improved multilingual capabilities allow Google to expand its language processing tool, Bard, to new languages. This expansion ensures that more users can benefit from this powerful linguistic tool. Additionally, PaLM 2 powers Google’s recently announced coding update, enhancing the coding experience for developers.

Enhanced Workspace Features: PaLM 2 plays a vital role in improving writing assistance in Gmail and Google Docs, as well as organizing functionalities in Google Sheets. By leveraging the capabilities of PaLM 2, these workspace features provide users with enhanced productivity, enabling them to complete tasks more efficiently.
Med-PaLM 2 is a specialized version of PaLM 2 that has been trained with medical knowledge. This model is capable of answering questions and summarizing insights from dense medical texts. It achieves state-of-the-art results in medical competency and has even surpassed the performance of human experts on U.S. Medical Licensing Exam-style questions. Google is now expanding Med-PaLM 2’s capabilities by incorporating multimodal features to synthesize information from X-rays and mammograms. This integration of visual data aims to improve patient outcomes by providing more comprehensive diagnostic support. In the coming months, Med-PaLM 2 will be made available to a select group of Cloud customers for feedback, ensuring that it is used safely and effectively.
Sec-PaLM, another specialized version of PaLM 2, has been trained specifically for security use cases. This variant, accessible through Google Cloud, utilizes AI to analyze and explain the behavior of potentially malicious scripts. By accurately identifying threats, Sec-PaLM assists in bolstering cybersecurity defenses for individuals and organizations. Its capabilities offer unprecedented insights into script behavior, enabling more efficient threat detection and mitigation.
To further expand the accessibility of PaLM 2, Google has been previewing the PaLM API with a small group of developers since March. Starting now, developers can sign up to use the PaLM 2 model directly. Additionally, customers have the option to utilize the model through Vertex AI, which ensures enterprise-grade privacy, security, and governance. PaLM 2’s capabilities are also harnessed by Duet AI for Google Cloud, an innovative generative AI collaborator designed to enhance user learning, development, and operational efficiency.
Advancing the Future of AI
PaLM 2 exemplifies the impact of highly capable models of various sizes and speeds, underscoring the immense benefits that versatile AI models can bring to individuals and businesses alike. Google remains steadfast in its commitment to releasing helpful and responsible AI tools in the present. Simultaneously, the company is actively working on creating even more powerful foundation models for the future.
To propel their progress further, Google is merging their Brain and DeepMind research teams into a unified unit. This collaborative effort will leverage the computational resources of Google while integrating the groundbreaking capabilities developed by DeepMind. By combining these two world-class teams, Google aims to not only enhance the products used by individuals daily but also pave the way for the next generation of AI models.
One of the ongoing projects within this unified unit is Gemini, a multimodal model designed from the ground up. Gemini’s development focuses on achieving high efficiency in tool and API integrations, enabling future innovations such as memory and planning. While still undergoing training, Gemini already exhibits multimodal capabilities previously unseen in prior models. Once fine-tuned and thoroughly tested for safety, Gemini will be made available in various sizes and capabilities, ensuring its deployment across different products, applications, and devices to benefit a wide range of users.
Conclusion
In conclusion, Google’s introduction of PaLM 2 showcases the continuous advancements in language modeling and AI capabilities. PaLM 2’s improved multilingual, reasoning, and coding capabilities enable it to support a diverse range of applications.
