GPT model

Timeline of Key Developments:

June 16, 2016 - OpenAI published research on generative models, which are trained by collecting a large amount of data in a specific domain and teaching the model to generate similar data.

September 19, 2019 - OpenAI published research on fine-tuning the GPT-2 language model with human preferences and feedback.

January 27, 2022 - OpenAI published research on InstructGPT models, the siblings of ChatGPT. These models show improved instruction-following ability, reduced fabrication of facts, and decreased toxic output.

November 30, 2022 - OpenAI introduced ChatGPT using GPT-3.5 as a part of a free research preview.

March 14, 2023 - OpenAI released GPT-4 in ChatGPT and Bing, promising better reliability, creativity, and problem-solving skills.

GPT-3

The GPT-3 (Generative Pretrained Transformer 3) is a groundbreaking AI model that leverages machine learning techniques to generate human-like text. This technology uses a language prediction model that utilizes the Transformer architecture. GPT-3 has 175 billion machine-learning parameters, which help train its ability to predict the likelihood of a word based on previous words used in the text. Ultimately, it can generate impressively coherent and context-relevant sentences.

Moreover, GPT-3 is fine-tuned using Human Feedback Reinforcement Learning (RLHF). This approach is a milestone in artificial intelligence, as it enables the creation of more advanced artificial intelligence models and is widely used as the underlying technology of various OpenAI models.

GPT-3.5

Released on March 1, 2023, GPT-3.5 is an enhanced version of GPT-3 because it has a set of advanced models that are proficient at understanding and generating natural language or code. GPT-3.5 has five different model variants, each with specialized capabilities. Four of them are specifically optimized for text completion tasks, and the remaining one has better performance in code completion tasks.

GPT-4

The GPT-4 model represents a new era in AI language models. It enhances the strengths of its predecessors, GPT-3 and GPT-3.5 while addressing its shortcomings. GPT-4 has been further fine-tuned to improve instruction-following ability, reduce the fabrication of facts, and decrease toxic output, making it more reliable and creative.

OpenAI's release of GPT-4 marked a milestone in ChatGPT's evolution, elevating its abilities to interpret and generate text with better contextual understanding and problem-solving skills. As the largest and most advanced model, GPT-4 has set the bar higher for future AI developments.

ChatGPT

ChatGPT is an advanced language model that mirrors human-like text generation in a conversational manner. Built upon the GPT-3 model, ChatGPT is specifically engineered to generate interactive responses to user inputs. With its ability to address follow-up queries, rectify mistakes, challenge fallacies, and refuse unsuitable requests, ChatGPT demonstrates a high degree of sophistication in dialogue engagement.

Fine-tuning

OpenAI's fine-tuning technique provides a way to extract optimal performance from AI models.

Its features include:

• Enhanced result quality,

• The capacity for training on a larger number of examples,

• Use shorter prompts to save token usages,

• and process requests at a quicker speed.

It works by training a pre-trained model like GPT-3 on a larger dataset than can be accommodated within a prompt, which helps improve model performance across various tasks.

Embeddings

Embeddings in OpenAI's context are measures of the relatedness of text strings. Such embeddings find extensive use in diverse areas like search operations, clustering, recommendations, anomaly detection, diversity measurement, and classification. The relatedness is captured in the form of vectors, with the distance between two vectors indicating their level of similarity.

Whisper

Whisper is a remarkable automatic speech recognition system that processes words collected from an extensive multilingual and multitasks training dataset. Whisper excels at handling different accents, technical language, and background noise with higher accuracy, which is excellent for English speech recognition. It’s super popular in the developer community. Also, you can use Whisper API.

DALL-E 2/Image generation

DALL-E 2, another impressive AI system from OpenAI, can generate realistic images and artwork based on natural language descriptions. Whether it's about creating original images, expanding existing ones, making realistic edits, or generating different variations of a given image, DALL-E 2 handles it all with the help of deep learning models.

Codex

OpenAI Codex translates natural language into code, aiding developers in their programming tasks. It supports multiple programming languages and understands and executes simple commands, thereby facilitating the creation of natural language interfaces for existing applications. Codex, the underlying model for GitHub Copilot, is an evolution of GPT-3 and utilizes a mix of natural language and billions of lines of source code for its training.

OpenAI API

OpenAI API is a cloud interface. Hosted on Microsoft Azure, you can access new AI models developed by OpenAI, such as DALL-E, Codex, and GPT-3, once OpenAI releases the model API.

Unlike most AI systems designed for a single use case, today's APIs provide a generic "text in, text out" interface, allowing users to try it on almost any English language task.

How to use it? Simply request access to integrate the API into your product, and then you can develop a brand-new application—for example, an image generator based on OpenAI's API.
