About this course

As AI agents become more sophisticated, the ability to remember past interactions is essential for creating truly personalized experiences. Without long-term memory, agents lose context and struggle to maintain coherent workflows. This course guides you through the foundational concepts of adding persistent memory to your AI applications. You will learn how to transition from stateless scripts to stateful agents that retrieve, update, and utilize historical data. What you'll learn: [1] Understand the core concepts of stateful AI agents and why context retention matters. [2] Explore the fundamentals of vector databases and how they store semantic information. [3] Implement long-term memory solutions using Mem0 to track user preferences and history. [4] Apply basic Retrieval-Augmented Generation (RAG) patterns to connect agents with stored knowledge. [5] Practice writing code to manage context windows and interact with embedding models effectively. The course begins by defining key terminology around AI memory and vector embeddings before moving into practical, text-based coding exercises. You will work through structured written lessons that build your understanding of state management step by step. This course is designed for beginners and aspiring developers who want to explore agentic AI; no prior experience with machine learning is required. Start reading today to give your AI applications the power of long-term memory.

Matagal na akong naghahanap ng paraan para hindi makalimot ang AI agent ko sa mga nakaraang usapan, at dito ko nakita ang sagot. Malinaw ang pagkakaexplica kung paano gamitin ang Mem0 para sa pangmatagalang memory, at yung paghahambing ng iba't ibang vector database ang pinakanagustuhan ko. Sumunod akong mabuti sa mga hakbang sa pag-store at pag-retrieve ng context, tapos gumana agad sa una kong subok. Mas naintindihan ko rin ngayon kung kailan dapat gumamit ng semantic search kaysa simpleng lookup. Sulit talaga para sa kahit sinong gustong gumawa ng stateful na agent.

This course finally made the concept of agent memory click for me. Working through Mem0 alongside a vector database showed exactly how an agent can remember context across sessions instead of starting from zero every time.

Good deep dive into how Mem0 handles short and long-term memory for agents. The vector database section drags a little in places, but the hands-on examples more than make up for it.

Het gedeelte over hoe Mem0 herinneringen opslaat en weer ophaalt met een vectordatabase was precies de uitleg die ik nodig had.

The way this course breaks down short-term versus long-term memory using Mem0 finally made agent state management make sense to me.

Bisher hatte ich nur eine vage Vorstellung davon, wie KI-Agenten sich über mehrere Sitzungen hinweg an Kontext erinnern sollen, aber dieser Kurs erklärt das Prinzip mit Mem0 wirklich greifbar. Die Kombination aus Kurzzeit- und Langzeitgedächtnis wird nicht nur theoretisch beschrieben, sondern direkt in Code umgesetzt, was das Verständnis enorm erleichtert. Besonders der Teil über die Vektordatenbank und wie relevante Erinnerungen dort abgerufen werden, war für mich der Aha-Moment des Kurses. Man merkt, dass der Dozent selbst mit solchen Systemen arbeitet, weil die Beispiele nie künstlich wirken. Am Ende hatte ich einen Agenten, der sich tatsächlich an frühere Gespräche erinnert, was ich vorher nur aus Theorie-Videos kannte.

Раньше я довольно смутно представлял, как агенты вообще что-то запоминают между сессиями, а тут всё разложено по полочкам через Mem0. Особенно понравилось, как объясняется разница между кратковременной и долговременной памятью и зачем вообще нужна векторная база в этой связке. Примеры кода не оторваны от реальности — сразу видно, что автор сам строил такие системы. К середине курса я уже собрал своего агента, который помнит контекст из прошлых разговоров, и это реально работает. Пожалуй, лучший курс из тех, что я видел на тему памяти агентов.

AIエージェントが会話の文脈をどうやって覚えておくのか、ずっと曖昧にしか理解できていなかったのですが、この講座でMem0の仕組みを実際に手を動かしながら学んでようやく腑に落ちました。短期記憶と長期記憶を分けて扱う部分の説明が特に丁寧で、なぜベクトルデータベースが必要なのかも自然に理解できます。コード例もおもちゃのようなものではなく、実際に使えるレベルまで踏み込んでいるのが良かったです。講座の後半では自分で作ったエージェントが過去の会話をちゃんと覚えているのを見て、素直に感動しました。次はこれを自分のプロジェクトに組み込んでみようと思っています。

Mem0とベクトルデータベースを使ってエージェントに記憶を持たせる仕組みが、こんなに分かりやすく説明されているとは思いませんでした。

Bom sobre memória vetorial, ritmo meio rápido.

Ik snapte tot nu toe nooit goed hoe een AI-agent info tussen sessies zou moeten onthouden, maar deze cursus legt dat via Mem0 heel concreet uit. Het onderscheid tussen kortetermijn- en langetermijngeheugen wordt niet alleen uitgelegd maar ook meteen in code gebouwd, wat het meteen tastbaar maakt. Het stuk over de vectordatabase en hoe relevante herinneringen daaruit worden opgehaald was voor mij het moment waarop alles op zijn plek viel. De voorbeelden voelen nooit kunstmatig, je merkt dat de docent dit soort systemen zelf bouwt. Aan het einde had ik een agent die daadwerkelijk terugverwijst naar eerdere gesprekken, iets wat ik voorheen alleen in theorie had gezien.
