**TLDR:** Most comprehensive Turkish technical guide for Few-Shot Learning prompt optimization: academic origins (Brown et al. 2020 GPT-3 paper, in-context learning discovery), 8 example selection strategies (random, similarity-based KATE, diversity, semantic, active learning), optimum example count analysis (1 vs 3 vs 5 vs 10 vs 32), ordering effects (Lu et al. 2022 'lost in middle'), delimiter and formatting best practices, Anthropic XML tags pattern, Few-Shot + CoT combination, recency + primacy bias, dynamic few-shot retrieval, prompt versioning, A/B test framework, 25+ Turkish practical examples, evaluation framework, production deployment.

## 1. Introduction

Few-Shot Learning teaches LLMs via examples in prompt. Brown et al. 2020 GPT-3 discovery. Foundation of modern prompt engineering.

## 2. Three Levels

Zero-shot (0 examples), One-shot (1), Few-shot (2-32+).

## 3. 8 Selection Strategies

Random, Similarity-based KATE, Diversity, Active Learning, Semantic Clustering, Coverage, Difficulty Curriculum, Dynamic Retrieval.

## 4. Optimum Count

3-5 sweet spot for most tasks. 1 minimum. 10+ diminishing returns.

## 5. Ordering Effects

Lost in the middle — primacy + recency. Critical examples at start + end.

## 6. Anthropic XML Pattern

Modern best practice for example structuring.

## 7. Production

Dynamic Few-Shot Retrieval (RAG + Few-Shot hybrid) for scale.

## 8. Conclusion

Few-Shot foundation technique, still valuable in 2026 for domain-specific + Turkish + structured output.
