Advanced Prompt Engineering: Techniques That Actually Work in 2025

By Jorge OsorioMay 5, 20256 min

Chain-of-thought, structured few-shot, defensive system prompts, and meta-prompting. Advanced techniques with real examples to get the most out of any LLM.

Prompt engineering has evolved from an informal art to a technical discipline with well-established patterns. Chain-of-thought improves reasoning on complex tasks, structured few-shot provides concrete examples of the expected format, and defensive system prompts prevent injections and unwanted behaviors. In our experience, the difference between a basic prompt and an optimized one can represent a 40% improvement in response quality.

We share the techniques we use daily in real projects.
