Summary
ChatGPT is a free chatbot developed by OpenAI. It uses Natural Language Processing (NLP) to answer questions, write content, summarize information and more.
GPT-4 is the latest version of OpenAI’s language model systems, available for a fee. It is a large multimodal model, accepting text and image inputs and emitting text outputs. It now includes DALLE·3, an image generator that you can refine and iterate. Users are able to edit DALL·E images in ChatGPT across web, iOS, and Android.
Features & Options
- Ask questions in multiple languages. ChatGPT can answer questions, help you learn, write code, brainstorm together, and much more in a large number of languages.
- Don’t share sensitive information. Chat history may be reviewed or used to improve OpenAI’s services. Learn more from ChatGPT’s Help Center.
- Be specific & check your facts. ChatGPT may give you inaccurate information especially when prompts are not sufficiently specific. It’s not intended to give advice.
- Image generated with ChatGPT and OpenAI API include metadata using C2PA specifications. C2PA is like a digital ID card for images, telling you where they came from, and helps identify when an image is AI generated.

Frequently Asked Questions
- What’s the difference between ChatGPT and GPT-4?
- According to OpenAI, “In a casual conversation, the distinction between GPT-3.5 (its current free version) and GPT-4 can be subtle. The difference comes out when the complexity of the task reaches a sufficient threshold—GPT-4 is more reliable, creative, and able to handle much more nuanced instructions than GPT-3.5.” ChatGPT 3.5 is available at no cost while GPT-4 is available for a fee.
- What is a hallucination?
- ChatGPT and other similar chatbots are known to “hallucinate” or provide outputs that sound plausible but are incorrect or unrelated. To reduce the likelihood of hallucinations, tell it that it's an expert in the topic you're prompting. For example, "You are an expert in public speaking."
