What is OpenAI?

OpenAI is an artificial intelligence research laboratory. It was founded in 2015 with the goal of promoting and developing friendly AI that benefits humanity, and is currently one of the leading organizations in the field of AI research and development.

OpenAI is known for developing cutting-edge AI technologies, including the GPT language model, and for conducting research on topics such as machine learning, robotics, and reinforcement learning.

What is GPT?

GPT (Generative Pre-trained Transformer) is an advanced language model developed by OpenAI. It is a machine learning model trained on a massive amount of text data from the internet, allowing it to generate human-like text. It is considered one of the most powerful language models available and is capable of performing a variety of natural language processing tasks, including text generation, translation, question answering, and summarization, among others.

GPT is a type of transformer neural network, which is a deep learning model used for natural language processing tasks. It is called "pre-trained" because it was trained on a large corpus of text data prior to being fine-tuned for specific tasks. This pre-training allows the model to learn general language patterns and knowledge, which can then be fine-tuned for specific tasks with smaller amounts of data.

GPT has been widely recognized for its ability to generate highly coherent and human-like text, leading to discussions about the potential and challenges of using AI in creative and strategic tasks that traditionally require human intelligence.

What is ChatGPT?

ChatGPT is an AI model developed by OpenAI that is designed to respond to text inputs in a human-like manner. This model is based on the GPT language model and utilizes this training to generate responses that are coherent, relevant, and in a natural language format.

This AI model can be used for various applications such as chatbots, customer service, and virtual assistants, and it has the potential to enhance the user experience in these areas. It is capable of understanding and generating text in a way that mimics human conversation, making it an ideal tool for companies and organizations looking to implement conversational AI systems.

How to use OpenAI models

To use GPT models, including ChatGPT, you typically need to access them through an API provided by OpenAI.

1. Create an OpenAI account. To use GPT models, you will need to open your own OpenAI account: sign up for OpenAI.
2. Create an API key. After signing up, you will need to obtain an API key that will allow you to access the GPT models through the OpenAI API. Go to the “API Keys” page in your OpenAI account and create a new secret key:
   
   
3. Integrate OpenAI API into your application. The next step is to write the code in your application to send requests to the GPT models and receive responses. You can write the code in any programming language such as Python, Java, or JavaScript. Detailed instructions, examples, and tutorials can be found in OpenAI Docs.
4. Send requests and get responses. Once API is integrated, you can start sending requests to the OpenAI models from your application.
   The request is usually made using HTTP, and the response will contain the generated text. Refer to OpenAI Docs: Making Requests to learn more about API parameters.

Important Note: While GPT models can generate human-like text, they may not always produce correct or accurate results, and it is up to the user to validate the results and make any necessary corrections. Additionally, access to the GPT models and API may be subject to terms and conditions set by OpenAI, such as usage limitations and data protection regulations.

How to launch your own GPT application on AWS using Altostra

Altostra has created an open-source gpt-web-app template you can use to deploy and launch your own ChatGPT-like application in a few minutes.

This is serverless web application that integrates GPT with a simple web UI, using the following Amazon Web Services (AWS) services:

1. Amazon Simple Storage Service (S3) - to store the web UI
2. Amazon CloudFront (CDN) - to host the web UI
3. AWS Lambdas - to process the user prompts and generate text using GPT
4. Amazon Simple Systems Manager (SSM) - to store the GPT API key securely
5. Amazon API Gateway - to expose the Lambda function as an API endpoint and trigger processing

To create and deploy a project, you first need to

1. Sign Up for Altostra
2. Make sure you have integrated your AWS account. For more information read Altostra Docs: Cloud Integration.
3. Create a new project using the gpt-web-app template.
   
   
4. Deploy a new stack of the project.
   
   
5. Wait for AWS to deploy your CloudFormation stack.
   Note: This may take up to 20 minutes for AWS to deploy CDN, but it usually takes less
6. Click on the Visit button to open your new GPT application, enter your API key and start chatting with GPT!
   
7. It's up to you now to change the Altostra gpt-web-app code to expand the app functionality as you wish.
8. To change the GPT model used by your application, read the instructions here.
9. For more information, read the template documentation.
