What is a Large Language Model (LLM)?

The introduction of ChatGPT on November 2022 marked a pivotal moment in the popularization and widespread acceptance of Generative AI and Large Language Models (LLMs). OpenAI demonstrated to the public how LLMs and AI technology can help companies and individuals automate tasks, stimulate creative thinking, and even aid in software coding — marking a new era of AI utilization.

At its core, LLMs are a type of artificial intelligence that handles various tasks involving natural language processing (NLP). These tasks include generating and categorizing text, providing conversational responses, and translating text between languages.

Large Language Models (LLMs) are exceptional in their ability to comprehend and replicate human language naturally. They can understand context, construct natural responses, and even emulate conversational nuances, resulting in interactions that resemble how real humans communicate with each other.

Large vs Small LLMs

The term 'large' refers to the number of parameters (weights and values) that the LLM can adjust and change as it trains. The largest LLMs like Open AI’s GPT-3, GPT-4 and Google’s PaLM 2, LaMDA, BERT, Bard, and Meta’s Llama 2 contain hundreds of millions to billions of parameters. Research teams like Technology Innovation Institute’s Falcon 40B, UC Berkeley’s Vicuna, Koala, as well as Stanford University’s Alpaca have also released their own large language models.

Despite the rise of massive LLMs, recent trends have shifted towards smaller, more accessible, and customizable models such as Ada, Atlas, and Cohere.

Smaller language models are not only more cost-efficient, but they are also much more accurate in achieving domain-specific business tasks. This is because they are trained and optimized on carefully-vetted data that addresses the exact use cases that users and businesses care about, rather than being trained on all publicly available data — which includes both good and bad data.

It’s not enough to just scrub the internet to train LLM.  Quality data counts - we all are going back to this truth   — Thomas Wolf, co-founder and CSO of Hugging Face

Custom LLMs

Users and businesses who want more control over responses can customize the data an LLM pulls from to modify their behavior and output. There are two main ways to achieve this:

1. Embedding

Large language models use embeddings to project textual data, such as words or sentences, into a high-dimensional vector space. This allows the LLM to capture semantic relationships and contextual nuances by categorizing texts into labels or categories, such as positive or negative, spam or not spam, news or opinion, and so on (Microsoft).

2. Fine-tuning

Fine-tuning large language models refers to the process of refining a pre-trained AI language model by training it on a narrower, task-specific dataset. This process helps the model improve and perform better when creating precise and relevant content, while still keeping its original abilities. When you fine-tune an AI model, it's like sending it to graduate school after it's finished undergrad.

What are AI Avatars?

Digital humans are interactive, AI-driven representations that have some of the characteristics, personality, knowledge, and mindset of a human.   — Gartner 2023

Avatars are virtual representations of users or objects in digital environments. Traditional avatars are always under the control and management of humans and cannot perform actions that are not programmed in advance. On the other hand, AI avatars and AI humans can interact with real people without relying on human agency or direction. They can also understand and make decisions themselves based on the context of the world around them.

Over the past few years, AI humans have made significant strides in appearing and sounding incredibly lifelike. DeepBrain AI claims their AI avatars look and act 96.5% similar to humans, and you can see how realistic Samsung’s STAR Labs digital humans look in the picture below.

Typically, hyper-realistic AI avatars are created in a recording studio with a real-life human model, but avatar creation can now also be done completely digitally, through self-recorded videos and pictures. or through face-swap technology — and the technology is only getting faster and easier to use.

Key elements of AI Avatars are:

  1. Hyper-Realistic Appearance: Digital humans are becoming increasingly more realistic and lifelike. While they are often created in a studio and then synthesized by a machine learning program, it is now becoming faster and easier to create digital avatars using just photos or self-filmed videos alone.
  2. Natural Body Movements: AI avatars use an algorithm called Generative Adversarial Network (GAN) to create smooth and natural mouth and body movements. AI Humans can even sync their lip movements realistically to any audio or text input.
  3. Low Latency Responses: DeepBrain AI reported a latency rate of less than 1 second between human input and avatar output. Conversational AI avatars are able to respond to queries with minimal delay, resulting in a conversational flow that is natural and realistic.
  4. Text-to-Speech (TTS): Text-to-speech (TTS) technology has come a long way since early voice assistants. Nowadays, TTS can produce extremely realistic voices in all languages. When combined with lip-syncing, it can generate a convincingly real, speaking digital human replica.

What are Conversational AI Avatars?

In 2023, AI avatar and LLM technologies have converged to create a powerful tool for users and change how companies improve how they engage with customers. Teams from DeepBrain AI, Soul Machine, Uneeq, and D-ID have already started making conversational AI Humans, and the results have been impressively natural and successful.

You can think of LLMs as the brains behind conversational digital humans, while AI avatars serve as the vessel or body. Together, they perform better than regular AI chatbots by mimicking the entire process of human communication, including nonverbal cues like facial expressions and body language.

Conversational digital humans are also equipped with powerful capabilities such as memory, emotions, and creativity to fully emulate human cognition and engagement. This technology offers endless possibilities for businesses seeking to create engaging and personalized experiences for their customers.

LLMs Bring AI Humans to Life

One of the most exciting aspects of using LLMs with conversational AI is the ability to create and customize their personas and personalities.

You can design a "customer service representative who makes cringe-inducing dad jokes," or a "friendly, bubbly café cashier who loves true crime." Companies can even give their brand mascot a persona for customers to engage in face-to-face conversations!

Startups like Inworld AI and Character.ai are already using LLMs to make multi-dimensional AI avatars with interesting personalities, backstories, and even flaws. Combined with conversational AI avatars, businesses can make special and fun experiences for users.

Imagine going to a Disneyland kiosk and getting directions from your favorite Disney character. Or having an AI version of your CEO welcome and talk to you on your day of work!
