Summary
ChatGPT is a free chatbot developed by OpenAI. It uses Natural Language Processing (NLP) to answer questions, write content, summarize information and more. Learn about the latest models.
GPT-4o (“o” for “omni”) is the latest version of OpenAI’s language model systems, available for free with usage limits, and additional features for paid users only. It is multimodal, accepting text, image, and audio inputs and outputs. Users can experience faster text generation, real-time conversations, improved non-English language capabilities, and more natural human-computer interactions. See the GPT-4o features available for free users, and learn about the model's full capabilities.
GPT-4o-mini was also released for free users as a more efficient model to replace GPT-3.5 (the previous free version). It offers improved performance, enhanced intelligence, and similar speed to GPT-3.5 at a lower cost.
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-4, GPT-4o, and GPT-4o-mini?
- GPT-4 and GPT-4o share similar features, but differ in their multimodal capabilities, efficiency, and language support.
- GPT-4 is mainly designed for text inputs and outputs, making it less capable of processing audio and images. For non-text input, it relies on other OpenAI models like DALL-E 3. GPT-4 is available to paid users.
- GPT-4o is optimized for real-time, conversational interactions. It handles text, audio, and image input, is faster, more cost-effective, and supports over 50 non-English languages. It has a free tier with usage limits, while additional features are available to paid users.
- GPT-4o-mini is a faster, lower-cost model designed for free users to replace GPT-3.5. It has improved performance, enhanced intelligence, and a similar speed to GPT-3.5, making it a powerful option. - 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."
