Introduction
In 2026, neural networks have become an integral part of our daily lives. But for AI to be truly useful, you need to know how to communicate with it. This is where prompt engineering comes in—the art of crafting queries to get accurate, structured, and helpful responses. On the ASI Biont platform, we combine this technology with modern learning: each course not only teaches you how to work with AI but also uses AI itself to generate educational materials. In this article, we'll break down the key techniques of prompt engineering and why everyone working with information should master them.
What Is Prompt Engineering and Why Do You Need It?
Prompt engineering is not just "writing a query." It's a systematic approach to interacting with large language models (LLMs) like GPT or Claude. A well-crafted prompt can turn a neural network from a generator of fluff into a powerful tool for analytics, coding, or creativity. Without a solid grasp of prompt engineering, you risk spending hours on edits or getting irrelevant answers.
Key Techniques You'll Master
- Zero-shot prompting — the most basic method. You give a task without examples. For instance: "Write a brief summary of an article about quantum computing." The model handles it, but the result may be generic.
- Few-shot prompting — you add 2–3 examples to your query. This dramatically improves accuracy. Example: "Translate these phrases into English. Example: 'Привет, как дела?' — 'Hello, how are you?'. Now: 'Где находится библиотека?'" This approach is often used in AI-assisted learning to set the style or format of the response.
- Chain-of-Thought (CoT) — you ask the model to "think aloud," breaking the task into steps. For example: "Solve the problem step by step: Vasya had 5 apples, he gave 2 to Petya, then bought 3 more. How many does he have now?" CoT is indispensable for logical and mathematical tasks.
- RAG (Retrieval-Augmented Generation) — a method where the model first searches a knowledge base and then generates an answer. This is the foundation of modern AI assistants that don't "hallucinate" but cite facts.
- Structured output — you force the model to produce a response in a strict format: JSON, table, list. This is critical for integrating AI into business processes.
How AI Helps in Learning at ASI Biont?
On the ASI Biont platform, every prompt engineering course is designed so you learn from real examples. AI automatically generates lessons tailored to your level. Instead of boring theories, you get practical cases: from setting up prompts for GPT to optimizing tokens for Claude.
Practical Examples
| Technique | Example Prompt | Result |
|---|---|---|
| Zero-shot | "Write 5 ideas for an Instagram post about ecology" | Generic ideas, but no details |
| Few-shot | "Here's an example of a good post: [text]. Now write a similar one about separate waste collection" | Precise, stylized response |
| Chain-of-Thought | "Explain how a Markov chain works, step by step" | Clear, step-by-step explanation |
| RAG | "Based on the document [link], answer: what types of plastic are recycled in Russia?" | Answer with citations from the source |
Special attention is given to token optimization. Each token costs money (if you use paid APIs). The ability to shorten a query without losing meaning is a skill that can save up to 50% of your budget.
Why Take the Course Now?
The world of AI tools changes every six months. What worked with GPT-3 may not work with GPT-5. The course "Prompt Engineering" on ASI Biont is regularly updated. You'll learn:
- How to adjust temperature and top_p for different tasks.
- How to use system prompts to control the model's role.
- How to avoid "hallucinations" using validation techniques.
And all of this—in text format, without videos, but with clear examples and assignments. Best of all—the course is completely free, with no restrictions. No freemium, no "p
