The Next-Gen Large Language Model

Google recently unveiled PaLM 2, its cutting-edge large language model (LLM) at the I/O developer conference. This next-generation model is set to revolutionize AI applications and power Google’s updated Bard chat tool, the company’s alternative to OpenAI’s ChatGPT. With its advanced capabilities, PaLM 2 will form the basis for numerous AI features that Google plans to introduce. Developers will have access to PaLM 2 through Google’s PaLM API, Firebase, and on Colab.

PaLM 2 Training and Infrastructure

Although Google has remained tight-lipped about the technical details of PaLM 2, it has revealed that the model was built on top of Google’s latest JAX and TPU v4 infrastructure. Furthermore, Google has opted not to disclose the parameter count of PaLM 2, which is a notable departure from the 540-billion parameter model of PaLM 1.

Moving Beyond Parameter Counts

According to DeepMind VP Zoubin Ghahramani, the size of the model is not necessarily indicative of its capabilities. Instead, Google has chosen to emphasize the capabilities of PaLM 2 and let users judge its performance based on their experiences with the model. As a result, Google has provided a family of models with varying sizes to cater to different needs.

Enhanced Capabilities of PaLM 2

PaLM 2 boasts significant improvements in common sense reasoning, mathematics, and logic. Google has trained the model on an extensive array of math and science texts, including mathematical expressions, to achieve these advanced capabilities.

Solving Math Puzzles and Reasoning

Large language models have historically struggled with handling mathematical questions without relying on third-party plugins. However, Google claims that PaLM 2 can effortlessly solve math puzzles, reason through problems, and even generate diagrams.

Improved Support for Writing and Debugging Code

PaLM 2 offers enhanced support for writing and debugging code, thanks to its training on 20 programming languages. These languages include popular choices like JavaScript and Python, as well as less common options such as Prolog, Verilog, and Fortran. PaLM 2 serves as the foundation for Google’s specialized coding and debugging model, Codey, which launched alongside PaLM 2 as part of its code completion and generation service.

Multilingual Excellence of PaLM 2

One of the most significant advancements of PaLM 2 is its ability to excel at multilingual tasks. The model was trained on a corpus featuring over 100 languages, allowing it to generate more nuanced phrasing than its predecessors.

The PaLM Family of Models

Google refers to PaLM as a family of models, which includes Codey and other specialized variants such as Med-PaLM and Sec-PaLM. Med-PaLM focuses on medical knowledge, while Sec-PaLM targets security use cases. There is also a smaller PaLM model designed to run on smartphones, opening up possibilities for more privacy-centric applications.

Mobile PaLM 2: A Future Possibility

Despite not committing to a specific timeline, Google has revealed that the smaller PaLM model can process 20 tokens per second. While not particularly fast, this processing speed may be acceptable for some use cases. Google has not specified which smartphone was used for testing this model.

Google’s Deliberate Approach to AI

It is no secret that Google has taken a cautious approach to launching AI features, and the company acknowledges this. Representatives from Google maintain that they are committed to developing these tools responsibly and with safety in mind. Naturally, this philosophy extends to PaLM as well.

Performance and Edge Case Handling

As the public has not had the opportunity to test PaLM before its announcement, it is difficult to determine how well the model performs and how it manages edge cases. However, Google’s dedication to responsible development and safety suggests that these concerns have been taken into account during the model’s creation.

The Future of AI with PaLM 2

With the introduction of PaLM, Google has made a significant leap forward in the world of AI and large language models. The enhanced capabilities of this next-gen model, combined with its potential for multilingual applications and code debugging, promise to bring new and exciting opportunities for developers and users alike.

Expanding the PaLM Ecosystem

As PaLM becomes more widely adopted, it is expected that the PaLM ecosystem will continue to grow and diversify. With specialized models like Codey, Med-PaLM, and Sec-PaLM already available, the potential for further specialized models and applications is vast.


Google’s PaLM represents a major milestone in the field of AI and large language models. Its advanced capabilities, improved support for multilingual tasks, and potential for integration into various applications make it a powerful tool for developers and businesses. As the PaLM family of models continues to expand and evolve, we can look forward to a new era of AI-driven innovation and progress.
