Large language model (LLM) APIs are set to revolutionize how we process language. Powered by deep learning and machine learning algorithms, LLM APIs provide unprecedented access to natural language understanding capabilities. By leveraging these new APIs, developers can now create applications capable of understanding and responding to written text in ways never seen before.

Below, we’ll compare the top LLM APIs on the market, from Bard to ChatGPT, PaLM, and others. We’ll also explore potential use cases for integrating these LLMs and consider the implications for language processing.

What Are LLMs?

Large language models (LLMs) are artificial intelligence models designed to process, analyze and generate natural language. In essence, these models are based on deep learning algorithms that analyze large volumes of text and can learn to process, generate, and understand language at a human-like level. Some of the most well-known LLMs include Google’s BERT (Bidirectional Encoder Representations from Transformers) and OpenAI’s GPT (Generative Pre-trained Transformer).

LLMs are fundamentally different from traditional natural language processing (NLP) techniques, which often rely on manually written rules to analyze and interpret text. Instead, LLMs are designed to learn and recognize patterns in language by processing massive amounts of text data. They use neural networks to understand how words are used together and create an internal representation of language that can be used for a wide range of language-related tasks.

Top Large Language Model (LLM) APIs

As natural language processing (NLP) becomes more advanced and in demand, many companies and organizations have been working hard to create robust large language models. Here are some of the best LLMs on the market today. All provide API access unless otherwise noted.

1. ChatGPT

Chatbots are one of the most exciting applications of LLMs, and ChatGPT is a great example of this. Powered by the GPT-4 language model, ChatGPT can engage in natural language conversations with users. ChatGPT is unique because it is trained on various topics, so it can assist with many tasks, answer questions, and have engaging conversations on various subjects. Using the ChatGPT API, you can quickly generate Python code, draft an email and even adapt to different conversational styles and contexts.

OpenAI, the company behind ChatGPT, provides API access to the underlying models. For example, here is an example request to the OpenAI Chat Completions API.

import openai

openai.ChatCompletion.create(
  model="gpt-3.5-turbo",
  messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Who won the world series in 2020?"},
        {"role": "assistant", "content": "The Los Angeles Dodgers won the World Series in 2020."},
        {"role": "user", "content": "Where was it played?"}
    ]

And the example response:

{
 'id': 'chatcmpl-6p9XYPYSTTRi0xEviKjjilqrWU2Ve',
 'object': 'chat.completion',
 'created': 1677649420,
 'model': 'gpt-3.5-turbo',
 'usage': {'prompt_tokens': 56, 'completion_tokens': 31, 'total_tokens': 87},
 'choices': [
   {
    'message': {
      'role': 'assistant',
      'content': 'The 2020 World Series was played in Arlington, Texas at the Globe Life Field, which was the new home stadium for the Texas Rangers.'},
    'finish_reason': 'stop',
    'index': 0
   }
  ]
}

2. Bard

Bard is an AI chatbot developed by Google that uses their Large Language Model (LLM) and LaMDA (Language Model for Dialogue Applications) to generate human-like text and images. Unlike Google Search, Bard is conversational, meaning users can write a prompt and receive a personalized response in natural language.

Bard is an exciting example of how LLMs can be used to create powerful conversational AI experiences. The system can generate text and images tailored to a specific user’s input, and it does so in a natural and engaging way. Currently, the API is request-only. So, to implement it, you must request access.

3. GooseAI

Another helpful LLM API available on the market is GooseAI. GooseAI is a fully managed NLP-as-a-Service, delivered via API, that offers a state-of-the-art selection of GPT-based language models at uncompromising speed.

Furthermore, GooseAI offers more flexibility and options regarding language models. It allows users to choose between different GPT models and customize them to fit their specific needs. The Goose.AI API was designed to be interchangeable with other related APIs, like OpenAI.

4. Cohere

Another player in the world of large language models is Cohere. This cutting-edge technology empowers developers and businesses to build incredible products with world-leading natural language processing (NLP) technology while keeping their data private and secure.

Cohere allows businesses of all sizes to explore, generate, and search for information in a new way. The models are pre-trained on billions of words, making the API easy to use and customize. This means that even smaller businesses can now take advantage of this powerful technology without breaking the bank.

5. Claude

Claude is a next-generation AI assistant based on Anthropic’s research that showcases the capabilities of LLM APIs. With Claude, developers can access a chat interface and API through the developer console to tap into the power of large language models.

Claude has a variety of use cases, including summarization, search, creative and collaborative writing, Q&A, coding, and more. Early customers have reported that Claude is less likely to produce harmful outputs, easier to converse with, and more steerable than other language models on the market.

6. LLaMA

One exciting model that deserves mention in the conversation about LLMs is LLaMA, which stands for Language Learning and Multimodal Analytics. The team at Meta AI developed LLaMA to specifically address the challenge of language modeling with less computing power.

LLaMA is particularly desirable in the large language model space because it requires fewer resources and less computing power to test new approaches, validate others’ work, and explore new use cases. It accomplishes this by taking a unique approach to model training and inference, leveraging transfer learning to build new models faster and with fewer resources. At the time of writing, the API is request-only.

7. PaLM

If you’re interested in LLMs, you’ll want to check out Pathways Language Model (PaLM) API. Developed by Google, PaLM provides an easy and safe way to build on top of language models, with an efficient model in terms of both size and capabilities.

Even better, PaLM is just one part of the broader MakerSuite offering from Pathways AI. This intuitive tool is perfect for quickly prototyping ideas and will have a range of features available soon, including prompt engineering, synthetic data generation, and custom-model tuning.
