คอร์สนี้อธิบายเรื่องการทดสอบแอปพลิเคชัน LLM ได้ชัดเจนมาก โดยเฉพาะส่วนที่พูดถึงการตรวจจับ hallucination และการออกแบบ metric สำหรับประเมินผล แถมมีตัวอย่างจากโปรเจกต์จริงให้ลองทำตามทีละขั้นด้วย เรียนจบแล้วรู้สึกว่าเขียน test case ได้เป็นระบบขึ้นเยอะ

About this course
As Large Language Models (LLMs) become central to modern software, ensuring their reliability, accuracy, and safety is more critical than ever. Building an AI application is only the first step; knowing how to systematically test and evaluate its outputs is what makes it production-ready. This text-based course will guide you through the core principles of LLM quality assurance. You will start with foundational AI terminology and gradually explore how to measure model performance, structure evaluation datasets, and implement regression tests. By reading through practical scenarios and written code snippets, you will discover how to transition from manual prompt-checking to automated, scalable testing methodologies. What you will learn: Understand foundational LLM concepts, including the differences between fine-tuning and Retrieval-Augmented Generation (RAG). Design and curate robust evaluation datasets tailored to specific application use cases. Apply modern evaluation metrics to assess text generation quality, relevance, and factual accuracy. Implement regression testing to ensure model updates or prompt changes do not degrade existing features. Evaluate RAG architectures using contemporary patterns like LLM-as-a-judge and context-relevance scoring. Practice basic security testing concepts to identify and mitigate prompt injection vulnerabilities. The curriculum flows logically from basic definitions of AI evaluation to practical testing workflows. You will read through step-by-step written examples that demonstrate how to set up reliable testing pipelines for modern AI applications. This course is designed for beginners, QA professionals, and aspiring developers with basic programming knowledge who want to learn how to test AI applications. No prior machine learning expertise is required. Start reading today to build the skills necessary to confidently evaluate and test modern LLM applications.

Finally a course that treats LLM evaluation as an actual engineering discipline instead of vague best practices.
ইভ্যালুয়েশন ডেটাসেট বানানো আর RAG সিস্টেম যাচাই করার অংশটা সত্যিই দারুণ কাজে লেগেছে।
The module on building evaluation datasets alone was worth going through this course slowly and taking notes.
इस कोर्स ने LLM एप्लिकेशन्स की टेस्टिंग को बिल्कुल नए नज़रिए से समझाया। हैलुसिनेशन डिटेक्ट करने और evaluation metrics बनाने वाले हिस्से खासकर बहुत उपयोगी लगे। हर वीडियो के बाद खुद से टेस्ट केस लिखने का अभ्यास दिया गया जिससे कॉन्सेप्ट अच्छे से बैठ गए।
Clear, practical, exactly what I needed.
Malinaw ang paliwanag tungkol sa pag-eevaluate ng LLM outputs, pero medyo mabilis ang bahagi tungkol sa mga scoring rubric kaya kailangan mo ulit-ulitin panoorin.
This gave me a real framework for thinking about hallucination detection and scoring rubrics instead of just eyeballing outputs. The section on building evaluation datasets was the most useful part for my actual work. My only complaint is the automation tooling demo felt a bit rushed near the end.
Aprendí a estructurar pruebas de regresión para prompts de una forma que nunca había visto explicada tan claramente.
Курс отлично объясняет, как выстраивать пайплайн оценки LLM-приложений — после третьего модуля я наконец понял, зачем нужны регрессионные тесты для промптов.
Changed how I test prompts entirely.
Ce cours couvre bien les bases de l'évaluation des applications LLM, avec des exemples concrets sur la détection des hallucinations et les métriques de scoring. Le rythme est un peu rapide sur la partie automatisation des tests, il faut parfois revenir en arrière. Dans l'ensemble ça m'a donné une méthode claire pour structurer mes propres tests.
El curso explica muy bien cómo diseñar casos de prueba para aplicaciones de LLM, aunque la parte de métricas automatizadas se queda un poco corta.
Solid intro to evaluating LLM outputs, though I wish there was more on setting up automated regression tests instead of just manual scoring.
Ich habe schon einige technische Kurse gemacht, aber dieser hier bringt das Thema LLM-Testing wirklich strukturiert auf den Punkt. Besonders gut fand ich den Teil über Halluzinationserkennung und wie man daraus konkrete Testfälle ableitet, das war vorher für mich immer ein bisschen diffus. Auch die Erklärung von Evaluationsmetriken wie Genauigkeit versus Konsistenz war anschaulich mit echten Beispielen unterlegt. Die Übungen zwischen den Lektionen zwingen einen dazu, selbst Testszenarien zu schreiben statt nur zuzuschauen, was den Lerneffekt deutlich erhöht. Am Ende hatte ich ein funktionierendes kleines Evaluationsskript, das ich direkt für ein eigenes Projekt anpassen konnte, und das Gefühl, das Thema jetzt wirklich im Griff zu haben. Für jeden, der von reinem Prompt-Basteln zu systematischem Testen wechseln will, ein echter Fortschritt.
LLM एप्लिकेशन के लिए टेस्ट केस डिज़ाइन करना सिखाने वाला यह कोर्स बहुत प्रैक्टिकल है और उदाहरण बिल्कुल असली प्रोजेक्ट जैसे हैं।
ハルシネーション検出の解説が特に良かった
O curso explica bem como montar testes para aplicações de LLM, mas senti falta de mais exemplos usando frameworks de avaliação automatizada.
