Is ChatGPT an open-source project?

ChatGPT, the conversational model developed by OpenAI, is not an open-source project. The underlying technology of ChatGPT is based on the GPT (Generative Pretrained Transformer) architecture, which has roots in research and models that have been shared publicly, such as GPT-2 and GPT-3. However, access to the full models and datasets used for training ChatGPT, particularly for later iterations like GPT-3.5 or GPT-4, is restricted and managed by OpenAI. While OpenAI has published some previous versions with more openness, such as releasing the smaller GPT-2 models, the organization provides controlled access to its latest AI systems through APIs that require adherence to their policies and terms of service. This ensures that users benefit from the advanced AI capabilities while mitigating potential risks associated with open dissemination of powerful language models.
