CLIP is the eyes that let it see images - not just read text and symbols.

​

GPT = Generative Pre-trained Transformer 3 (GPT-3) is an autoregressive language model that uses deep learning to produce human-like text. Given an initial text as prompt, it will produce text that continues the prompt.

CHATGPT = Special trained version of GPT3.5 for chat.

DALL-E = DALL-E (stylized as DALL·E) and DALL-E 2 are deep learning models developed to generate digital images from natural language descriptions, called "prompts".

CLIP = CLIP does the opposite of DALL-E: it creates a text-description for a given image. Read more here: https://openai.com/blog/clip/
