Frequently Asked Questions
What is the difference between GPT-4 and the o-series (o1/o3)?
GPT-4o is optimized for speed and multimodal interaction, while the o-series models are 'thinking' models that use a chain-of-thought process to solve much harder logical and mathematical problems.
Is ChatGPT Plus worth it?
Yes, for power users. It provides priority access to the latest models (like GPT-4o and o3), DALL-E 3, the GPT Store, and advanced data analysis features.
Does OpenAI store my conversations?
Consumer data is used for training unless you use 'Temporary Chat' or opt out. Enterprise and API data are NOT used for training foundational models.
Can OpenAI models generate video?
While Sora (OpenAI's video model) is not yet fully public, GPT-4o can analyze video inputs, and full video generation is expected in the near future.
