What is Google’s Generative AI Called?

Google has been developing advanced generative AI models to power new conversational search features and other applications. But what is the actual name of the AI system behind Google’s new generative capabilities? Let’s explore the key language models and technologies that comprise Google’s ambitious push into generative AI.

LaMDA – Language Model for Dialogue Applications

One of the most prominent generative AI systems created by Google is called LaMDA, which stands for Language Model for Dialogue Applications. LaMDA was unveiled by Google in 2021.

It is a neural network conversational agent designed to have natural conversations on a wide range of topics through text interactions. LaMDA has been fine-tuned on dialog representing how humans communicate.

Some key capabilities of LaMDA:

  • Maintain coherent, interesting multi-turn conversations
  • Discuss complex topics requiring world knowledge
  • Generate diverse, high-quality responses
  • Convey a unique personality customized for each conversation

LaMDA represented a major advance in Google’s conversational AI efforts thanks to its neural network architecture and sheer scale, with over 137 billion parameters.

Google has utilized LaMDA in experimental conversational systems like the AI Test Kitchen. It also provides the backbone for the new generative AI search features in Google that aim to offer more helpful, conversational responses to user queries.

PaLM – Pathways Language Model

In April 2022, Google unveiled its Pathways Language Model (PaLM), considered one of the largest and most advanced language models ever created.

PaLM has an astonishing 540 billion parameters, over 4 times more than GPT-3. It achieved state-of-the-art results across natural language processing tasks.

Some key capabilities and attributes of PaLM:

  • Can read and write texts up to 2048 words in length
  • Trained on 1.56 trillion words from webpages, books, Wikipedia, and other online sources
  • Uses “pathways” structure to improve multi-modal understanding and common sense
  • State-of-the-art results on SuperGLUE benchmark for language understanding
  • Can perform mathematical reasoning, answer science exam questions, and complete coding challenges

PaLM represents a massive leap forward in generative language modeling. Google is leveraging PaLM to enhance search, conversational systems, and other applications with more robust natural language capabilities.

Parti – Parallel Interaction Model

In November 2022, Google discussed an emerging model called Parti – short for Parallel Interaction Model.

Parti has 1.2 trillion parameters, twice as many as PaLM. It is an ensemble model, meaning multiple models can operate in parallel to boost capabilities.

Key features of Parti include:

  • Parallel ensemble architecture with multiple expert models
  • 1.2 trillion parameters total across all experts
  • Trained on dialogue data to support conversational applications
  • Specialist modules for specific types of conversations and knowledge
  • State-of-the-art results on natural language tasks
  • Able to rapidly incorporate new information and skills by training new expert models

Google states Parti represents a milestone in developing AI assistants that can have helpful, knowledgeable conversations spanning many topics. The ensemble architecture allows partitioning knowledge into experts, improving quality.

Parti is not yet fully launched, but demonstrates Google’s continued momentum in generative AI research. The company aims to eventually integrate Parti into products like Google Search and Google Assistant.

Supporting Technologies

In addition to flagship language models like LaMDA, PaLM and Parti, Google has developed other key technologies to enable generative AI applications:

  • RankBrain – AI system for understanding search queries and matching them to web pages. Helps power Google Search’s language understanding capabilities.
  • Knowledge Graph – Database of real-world entities and relationships that aids language models with factual knowledge. Critical for high-quality informational responses.
  • Meena – Conversational agent focused on depth, personality and engaging chit-chat ability through neural network training.
  • T5 – Text-to-text transfer transformer framework effective for language generation tasks like translation, summarization and question answering.

These and other tools supplement the core language models to enhance the quality and capabilities of Google’s overall generative AI stack.

Recent Progress

Google has been continuously iterating on and scaling up its generative models over the past several years:

  • 2017 – Smart Reply in Gmail leverages early seq2seq models to suggest response text
  • 2018 – Duplex system for automated booking conversations via RNN, BERT architectures
  • 2020 – Meena chatbot reached 79% human preference rating in conversations
  • 2021 – LaMDA unveiled with 137 billion parameters, impressive interactive ability
  • 2022 – PaLM launched with 540 billion parameters and state-of-the-art NLP performance
  • 2022 – New conversational AI search features roll out in Google Search, powered by LaMDA
  • 2022 – Parti discussed as Google’s next major ensemble model, currently in development

Google has established itself as one of the research leaders in generative AI, as evidenced by models like LaMDA, PaLM and Parti. The company continues pushing boundaries in its bid to power more helpful, conversational AI applications.

Google has established itself as one of the leading innovators in generative artificial intelligence, as demonstrated by models like LaMDA, PaLM, and the emerging Parti. These large neural network architectures trained on massive datasets have achieved state-of-the-art conversational ability and natural language understanding.

Central to Google’s progress are technologies like RankBrain, Knowledge Graph, Meena and T5 which provide critical supporting capabilities. The company has rapidly iterated and expanded its generative models since early tools like Smart Reply.

With each new system disclosed, such as the 1.2 trillion parameter Parti currently in development, Google aims to push boundaries on the size and sophistication of models. The overarching goal is to integrate these emerging generative AIs into products like Search, Assistant and Gmail to transform how people find information and interact with technology.

While challenges remain around limitations of current systems, Google has established a commanding lead in generative AI research. With models like LaMDA already powering new conversational search features, users are starting to experience applications of Google’s expanding generative capabilities firsthand. The future points to a new era of much more helpful, human-like interaction with artificial intelligence across Google’s products and services.
