Technical writing has been part of my job description for the past 3 years. And ever since ChatGPT launched, I’ve been experimenting with different workflows and debating about how much to even use AI in my writing process . This week I overheard someone say „If your first draft isn’t written with AI, you’re doing it wrong“. Sorry, but I strongly disagree. And when I learned this week that Thariq…
LLMs have been trained on vast amounts of shell sessions and codebases. That’s why agents are naturally good at using CLIs and navigating filesystems. A recent blog post describing how LangSmith Agent Builder’s memory system is built on a filesystem kicked off a discussion about whether “filesystems are all you need”. Harrison Chase, LangChain’s CEO and the blog’s author, later clarified that they…
In this notebook, we will explore the core concepts of GRPO (Group Relative Policy Optimization) by fine-tuning LFM2.5-1.2B-Instruct using Unsloth . GRPO is a reinforcement learning algorithm designed for training language models with reward signals instead of labeled examples. In contrast to supervised fine-tuning (SFT), where you tell the model the exact right answer, GRPO lets the model explore…
This week I attended a local meetup that revolved around the topic of “local AI”. Throughout different sessions and conversations, I noticed a recurring theme: How dependent we already are on our AI systems. I have adapted AI into my day-to-day workflow, but I don’t use AI for 100% of my work. And I’d argue I could do my job without it. When I wrote this, I realized that’s what someone with a…
One thing I pride myself on is making great technical diagrams. But those I make manually, and they take time. Boxes are placed intentionally. Colors, lines, and arrows that actually mean something. Proportions and placement to reduce mental load. A good diagram is a form of thinking made visible. It takes time to get right. Recently, I saw someone make an amazing technical drawing. Naturally, I…
Ever since I started writing on the internet, I always thought that by the time I published 100 blogs, I would be good. I’ve published 90 so far and just realized I’ve been doing it wrong. For me, writing is learning. When I learn a new topic, I write an explainer. When I play with a new developer tool, I write a tutorial. That’s why the majority of my blogs are tutorials and explainers. In an…

Developer Experience and User Experience are two key considerations when shaping a product. Today, software products are no longer exclusively used by humans but also by AI agents. This shift requires a new lens to design your product: Agent Experience. The term “Agent Experience (AX)” was first coined by Mathias Biilmann, Netlify’s CEO, in January 2025 as the “holistic experience AI agents will…
I’m digesting the current “filesystem vs database” debate for agent memory. Currently I’m seeing 2 camps in how we build agent memory: On the one side, we have the “file interfaces are all you need” camp. n the other side, we have the “filesystems are just bad databases” camp. “File interfaces are all you need” camp Leaders like Anthropic, Letta, Langchain & LlamaIndex are leaning towards file…
