What is ChatGPT?
ChatGPT is an AI chatbot built by OpenAI, launched in late 2022 and now used by over 200 million people worldwide. It uses large language models (LLMs) to understand and generate human-like text, making it useful for writing, research, coding, analysis and general problem-solving.
The free version uses GPT-4o mini which is still extremely capable for most tasks. ChatGPT Plus ($20/mo) unlocks the full GPT-4o model, image generation via DALL-E and access to GPT-4o with browsing. For marketers it's a powerful writing and brainstorming tool. For accountants it can help draft client communications, analyse data and explain complex regulations.
