GPT stands for Generative Pre-trained Transformer. “Generative” means that ChatGPT, as a chatbot, generates text based on prompts. “Pre-trained” means that the language model was trained on a huge corpus of text — in this case, text from the Internet – prior to its release. “Transformer” has to do with how the model learns and studies its responses for coherency. OpenAI developed ChatGPT and released the app on November 30, 2022. It has a knowledge cutoff of September 2021, meaning that, among other things, you can’t ask current versions of ChatGPT to summarize major events in world news after September 2021. As of July 2023, GPT-4 is the latest LLM released by OpenAI. It was first offered on March 14, 2023 – also with a knowledge cutoff of September 2021. On July 6, a subset of users were given access to the API for GPT-4. Limited, non-programmatic access to GPT-4 is provided to new users who sign up for ChatGPT Plus, which currently costs $20/month.
