Introduction
OpenAI is the company behind ChatGPT, and this entry is its official entry.
The product line for ordinary users is centered on ChatGPT and is available on web pages, desktops and mobile phones. It has expanded from the initial plain text dialogue to network search, file analysis, image generation, voice dialogue and an agent mode that can call tools to work continuously.
It is an API platform for developers. The model is iterated by generation. The same generation is usually divided into different specifications and price brackets. The billing details of long context, caching and batch processing need to be read in separate documents.
The company's focus in recent years has obviously been in two directions: first, integrating models into real workflows, and second, computing infrastructure.
Domestic users need to be reminded of access restrictions. The official website and services cannot be used directly in some areas, and there are thresholds for registration and payment. Please confirm your conditions before actual use.
In addition, versions in this industry change very quickly. For specific capabilities and prices of a certain model, please refer to the current documents on the official website. Any representation may be out of date.
