Chat GPT, powered by the advanced GPT-3 language model from OpenAI, has reached 1 million users only in 5 days. Facebook, Netflix, Instagram, and Twitter could reach this number in 300, 1200, 75, and 720 days. With 175 billion parameters, GPT-3 can generate writing that closely resembles human language. Chat GPT can engage in multiple ongoing conversations, understand and respond to natural language input, and offer customized and interactive assistance. This makes Chat GPT a promising tool for open education, as it can improve the independence and autonomy of autodidactic learners, while also being both practical and adaptable. By providing personalized support, direction, and feedback, Chat GPT has the potential to increase motivation and engagement among autodidactic learners.
