ChatGPT

ChatGPT is a conversation‑focused artificial intelligence that interprets natural language prompts and delivers human‑like responses.

It is built on large language models trained via supervised learning and reinforcement learning from human feedback, enabling it to plan, write, analyze, code, and reason across diverse domains.

The system solves everyday and complex business problems—from drafting documents and summarizing content to multi‑step reasoning and integrating tools for web search, file analysis, and image handling.

• Multi‑modal inputs and outputs: Accepts and generates text, images, voice, uploaded files—enabling flexible workflows like interpreting diagrams or drafting visual mockups.
