Google announced its new large language model (LLM), PaLM 2, at the Google I/O developers conference on May 10, 2023. The language model is one of the terrific inventions in the AI world and a close competitor to Open AI’s latest LLM, GPT-4.
While announcing this latest invention, Sundar Pichai unveiled that PaLM 2 has already been integrated into some Google products, including Google Bard AI. It is the successor of the Pathways Language Model (PaLM), released in 2022. The launch of this new Large Language Model has added a new product to the already-running AI race. And people are eager to know more about PaLM 2.
This guide shares in-depth details about Google PaLM 2, including its overview, features, and specifications. Read till the end to find all your answers!
What is Google PaLM 2?
PaLM 2 is a language model that Google is deploying to bring AI capabilities to all of its products, including Gmail, Google Docs and Bard. Similar to other language models like GPT-4, PaLM 2 is capable of powering AI-based chatbots.
According to Google’s official technical report, PaLM 2 outperforms most LLMs, including PaLM, in various tasks. For example, it beats other models when it comes to natural language generation, translation, and reasoning.
PaLM 2 is a multilingual model supporting over 100 languages. It is also trained using a massive dataset with reasoning-based web pages and scientific papers. The model is also trained on publicly available source codes to generate high-quality programs.
PaLM 2 is a powerful LLM capable of performing various tasks, including summarization, answering questions, generating images, audio, or video, generating text, and providing grammatical suggestions.
Further, in its blog post, Google announced that the model would have four different versions based on their sizes: Gecko, Otter, Bison, and Unicorn, where Gecko is the smallest and Unicorn the largest. Gecko is ideal for mobile devices since it is lightweight and fast. Users can expect to use the upcoming LLMs on their mobile devices.
Is Google Bard using PaLM 2?
On May 10, 2023, Google announced new updates to its latest AI model, Google Bard. According to the announcement, PaLM 2 now powers Google Bard. Google has also removed the waiting list from Bard, making the platform accessible to over 180 countries.
Google Bard was recently updated to use PaLM 2 to respond to user queries. PaLM 2’s advanced reasoning, coding, and text generation features make Google Bard more powerful and efficient. That means if you use Google Bard for generating code, translating text, or summarizing content, the responses will be generated by PaLM 2.
What is the difference between Google PaLM and LaMDA?
LaMDA (Language Models for Dialog Applications) is a transformer-based neural language model developed for Dialog systems. The model is trained with 137 billion parameters and teaching models. It generates responses for textual and image-based inputs in various contexts and styles.
PaLM (Pathways Language Model) is a large-scale language generation model developed for large-scale language generation tasks. The model is highly-scalable and capable of processing large amounts of data simultaneously.
PaLM was released in 2022 and upgraded to PaLM 2 in 2023. LaMDA was released in 2021 specifically for dialogue-based systems. Until now, Google’s Bard AI was powered by LaMDA. However, the tech giant recently upgraded Bard to use PaLM.
Both language models are designed to give natural responses to human queries. However, PaLM is a smaller, faster, and more efficient language model with several advanced functionalities compared to LaMDA.
Can I Use Google PaLM AI?
You cannot access PaLM 2 AI directly as it is a language model. The platform is integrated into other applications that use PaLM 2 to respond to user queries. You can experience Google PaLM 2 and its features using such platforms. Some applications supported by Google PaLM 2 include Bard, Med PaLM 2, Sec PaLM, and Workspace apps like Gmail and Google Docs.
PaLM 2 vs GPT-4?
PaLM 2 and GPT-4 are language models. Open AI developed GPT-4, while Google developed PaLM 2. Both models are used for language generation and processing. However, they differ from each other in several aspects. Some significant differences between PaLM 2 and GPT-4 are as listed below.
- Google PaLM 2 answers queries faster and more efficiently than GPT-4.
- Google PaLM 2 powers Google Bard, while GPT-4 powers ChatGPT-4 (ChatGPT’s paid version).
- PaLM 2 has four submodels, and GPT-4 has twelve submodels.
- PaLM 2 is not a multimodal language model, while GPT-4 is a multimodal language model.
- PaLM 2 is a much smaller language model compared to GPT-4.
- PaLM 2’s submodel Gecko will be available on mobile devices.
PaLM 2 is the latest language model by Google. The model has advanced functionalities compared to PaLM and existing language models. Google’s Bard and 25 other applications are powered by PaLM 2. The model is a tough competitor of GPT-4 but is much smaller and more efficient.
With the launch of PaLM 2, internet users expect more incredible inventions from Google and other AI researchers. Google has also announced that the company will release a new project Gemini soon. As you wait for it, explore what Google PaLM 2 has for its users!
