It's becoming more and more common for agents to skip embedding search entirely. It seems like they do just fine with grep, find and other command-line tools!

How is that possible? Is an agent equipped with a few keyword-search tools really able to outperform a vector DB?

Let's find out.

🐟 Your agent can be phished, just like a human can. Do you know how that happens?

In this post I go through all the steps I showed during the talk and offer some advice to protect your agents from this class of attacks. Stay safe!

If LLMs are stateless, how can they remember what the user told them in the past? Let’s have a look at the most common implementations of LLM memory, from simple chat history management to RAG-based approaches.

Do you also use #Colab for workshops and tutorials on #LLMs? Today I decided to write a small widget to make my next talk more interactive: a very simple chat UI that lives in the output cell without blocking the notebook's execution.

Next week at the Agentic AI Summit (https://summit.ai) I will walk you through the process of transforming your RAG pipeline into an AI Agent - in code, step by step 👣
