Introduction to ChatGPT in 2026
ChatGPT, developed by OpenAI, remains the world’s most widely used AI assistant in 2026, with over 300 million weekly active users. Since its launch in late 2022, the tool has evolved dramatically: the GPT-4o model now offers multimodal capabilities (text, image, voice, video) and impressive speed. This guide will give you all the keys to get the most out of it.

The Art of Prompting: Essential Techniques
The quality of your results directly depends on the quality of your prompts. Here are the fundamental techniques:
1. Be Specific and Contextual
Instead of asking "Write me an email," specify: "Write a professional email to my client announcing a 2-day delivery delay. The tone should be apologetic but reassuring. The client’s name is Mr. Smith and the project involves a website." The more context, the better the output.
2. Assign a Role
Start with "You are an expert in...". For example: "You are a certified nutritionist with 15 years of experience. Create a weekly meal plan for a 30-year-old who wants to lose 10 pounds." This technique dramatically improves response relevance.
3. Specify the Output Format
Define the expected format: table, bullet points, JSON, code, structured paragraphs. For example: "Present your answer as a table with columns: Tool, Price, Pros, Cons."
4. Chain of Thought
Ask ChatGPT to reason step by step. Simply add "Think step by step before answering" to your prompt. This method is particularly effective for logic, math, and strategy problems.
5. Few-Shot Prompting
Provide examples of what you expect. If you’re asking it to rephrase sentences, give 2–3 input/output examples. ChatGPT will immediately understand the pattern you want.
