I share how I use Hermes Agent daily as a customizable, always-on assistant that lives on a remote server and talks to me via Telegram. From coding on the go and reactive reminders, to job monitoring, calendar automation, flight search via a CLI, writing prep, and early stabs at fitness coaching, I explain why Hermes clicked for me—especially its cron-based reminders and automatic skill creation—w...

If there's one thing Retrospectiva does for me - other than giving me an excuse to write for you of course - it's making me realise how fast time moves. It's June already - and May was – well – hectic to say the least. Data Makers Fest was awesome - and I absolutely love Porto …

About 6 months ago I wrote a small rant on how open source TTS models still sucked . 6 months later, I'm happy to report that isn't the case anymore. January this year, Qwen , the famous Chinese AI lab, released Qwen3-TTS , an open-weights series of TTS models. The release included 2 …

Educational score over time vs. document count for Bagaco v2 A couple of months ago I released Bagaço - a pretraining dataset for European Portuguese. The idea was simple: take the FineWeb 2 dataset, limit it to web pages that look like they came from Portugal, and classify them into categories …

My Hermes agent – Saramago – giving me coaching feedback and looking for the ideal flights for an upcoming trip. Another month bites the dust. We've been back in Denmark for the past couple of weeks. I often joke that these are the only months in the year where Copenhagen is actually …

In December 2024, the Portuguese government announced AMÁLIA: a 5.5 Million Euro investment on a large-scale LLM for European Portuguese 1 . The other day, while building an overview of the different Portuguese NLP efforts, I stumbled upon the technical report ! I couldn't believe my eyes. Much to talk about …

Well, now would you look at that. Article 100 on this website. Ten years of writing on this small corner of the web. I'm writing this month's newsletter from my favourite place: the airplane. Happy Easter if you celebrate. With clients spread across time zones, I didn't really get the …

As you get older, life becomes complicated. Not in a bad way. There’s just more going on. We don’t all want to run marathons. Maybe you want to run a parkrun . Maybe you want to gradually increase your volume. Maybe you don't want to run at all. Whatever …

Given some text in Portuguese, how easy is it to determine if it's from Brazil or Portugal 1 ? For native speakers, this is pretty easy – it's almost a feeling. But for machines: not so much. This might seem like a useless problem at first. But in the age of language …

Happy February! Just like that, we are close to wrapping up the first quarter of 2026. After quite some time roaming around, we finally flew back home to Copenhagen. It's cold, windy, and grey, but it's also calm, organized, and cozy. Most of all: it's home . Another good thing about …

Let's say your goal is to train a Large Language Model only on European Portuguese. Where do you start? What datasets are out there? What websites are being scraped for the large black box? Bagaço - named after the popular Portuguese moonshine - is a small step in that direction. In June …

Well—that was quick. Just like that, the first month of the year is gone. Winter blues would normally peak around this time. But not this year. We're spending time with family in my favorite place on Earth, somewhere along the Adriatic coast of Italy, in the Marche region. It's …

Let's face it. It might just be the year of agents. If you work in tech and your workflow hasn't changed in the last year or so - you're probably doing something wrong. For those of you who have. It's fun. We're building more than ever before! But there's a dark …

I get up feeling sleepy. I lace up my running shoes and head out the door. I fire up my favourite podcast. "This show is brought to you by..." I hate ads. I understand the attention economy. Companies are capitalizing more and more on everyone's time. I have nothing against …

And just like that, it's the end of the year again. We did not expect to make it to the South for Christmas this year. Getting a passport for a newborn is a painful, bureaucracy-filled process, especially for a Portuguese-Italian baby born in Denmark. But somehow—magically—the Italian embassy …

Benchmarking calorie prediction for Taralli There's something very funny about the current Machine Learning and AI landscape. If you're in the field you probably heard about it. "Vibes" they call it. When someone wants to test something out, they conduct a "vibe test". I call bullshit. How are you supposed …

Big news in the state of Denmark. And no, nothing's rotten . Allegra just came into the world. As she takes a nap, I take the opportunity to write November's Retrospectiva update. The most relevant thing this month is probably the release of my recent book about DeepSeek . It's nice to …

Back in May this year, my longtime friend Alex reached out and asked me if I wanted to collaborate with him on a book about DeepSeek. I would love to tell you the story of how I thought long and hard before getting back to him. I didn't. I just …

or at least the open versions of it. I have this very stupid rule. A couple of years ago I decided to turn this blog into a podcast . At the time, I decided to make up a stupid rule: whatever model I use to clone my voice and generate article …

Welcome to Retrospectiva. Retrospectiva is a monthly update about what I’ve been up to. In the age of LLMs, I’ve heard many argue that it’s hard (and useless) to write anything at all anymore. When anyone can prompt a model and get some text from the magic …

Why do this? A small dataset of news headlines GPT2 in PyTorch Pre-training headlines in Portuguese Supervised fine-tuning (SFT) on Portuguese from Portugal Reinforcement Learning (GRPO) for sports news Final thoughts & Acknowledgements Why do this? ML and AI are moving at an incredible pace. The amount of research coming out …

The world moves fast, faster every day. For those who work with technology - and even those who don't - it's hard to keep up with the news. But I've always enjoyed staying up to date with what is happening, and my main tool to get it done hasn't changed in years …

It's that time of year again. As usual, we took a couple of weeks off and came south: a bit of Portugal, a bit of Italy, a lot of friends and family. My family has a long-running joke that I hate people and love my computer. That's not (entirely) true …

A couple of weeks ago in Lisbon, I went to a friend's birthday dinner. In front of …

..but they can also be a lot of fun. If you work in tech, I'd say there's a 98% chance you've heard about it. MCPs are the future of agents, MCPs will be everywhere, MCPs are the future. The Model Context Protocol, first introduced by Anthropic is blowing up. For …
