What is ChatGPT?
ChatGPT is an advanced AI-powered chatbot developed by OpenAI, designed to generate human-like responses in conversations. Built on deep learning and natural language processing (NLP), ChatGPT understands, processes, and generates text, making it a powerful tool for various applications.
Key Features of ChatGPT:
- Conversational AI: Engages in realistic and meaningful conversations.
- Multilingual Support: Understands and translates over 100 languages.
- Content Creation: Helps with writing, brainstorming, and summarizing.
- Code Assistance: Supports programming with explanations and debugging.
- AI-Powered Research: Provides instant insights and structured information.
ChatGPT has evolved through different versions over time (GPT-3.5, GPT-4, GPT-4o, GPT-4.5, and GPT-5), each improving in accuracy, speed, and contextual understanding. GPT-5, introduced in August 2025, is now the default model powering ChatGPT, bringing together OpenAI’s most advanced reasoning and multimodal capabilities in one unified system. This latest version is significantly smarter and more reliable – it produces far fewer false outputs (hallucinations) than its predecessors. It also features a massive context window (up to ~256k tokens, i.e. hundreds of pages of text), allowing extremely long conversations or documents to be handled without losing context.
