If Developers Build on Chinese Open-Weight Models, Who Leads AI?
If Developers Build on Chinese Open-Weight Models, Who Leads AI? Aug 3, 2026 4696 “It would be sad if local models were not an option and there were only proprietary models. It’s good to have alternatives. Competition is good for business.”— Sebastian Raschka, on open-weight AIKimi K3’s weights landed about an hour before Hugo Bowne-Anderson and Sebastian Raschka went live. Sebastian had already updated his architecture diagram. That speed captures his approach to the current m
Four Months Inside a Production AI Agent: What Real Users Changed
Four Months Inside a Production AI Agent: What Real Users Changed Jul 25, 2026 3879 When ML/AI Engineer William Horton last joined me, Maven Assistant had reached its first external users the day before. The healthcare AI agent was available to 20 percent of Maven Clinic’s users, and the team had deliberately withheld answers about benefits. A wrong response could shape a decision involving $15,000 of fertility coverage, and the evals had not earned the right to ship it.Four mont
Building an Enterprise AI Agent for Healthcare
Building an Enterprise AI Agent for Healthcare Jul 17, 2026 4134 Every capability in an agent needs its own evidence and release bar. A model-provider slip, an incorrect tool call, and a wrong fertility-benefits answer should not be held to the same pass rate.William Horton, Staff AI Engineer at Maven Clinic, joined us the day after Maven Assistant reached its first external users. The agent helps members inside Maven Clinic’s women’s and family healthcare plat
What Claude Fable Means for Coding Agents
What Claude Fable Means for Coding Agents Jul 8, 2026 3745 Nicolay Gerold works all day and night on AMP, one of the most interesting coding-agent harnesses out there.If you’re building with coding agents, this conversation will help you understand: * when to trust the model, * when to build harnesses around it,* which model is worth paying for, * which programming languages gives the agent better feedback, and * when to take the keyboard back.Coding-agen
The Future of Agentic Data Science
The Future of Agentic Data Science May 25, 2026 3877 So I think we’re really at a historical moment, and the opportunity is massive. Almost 15 years ago, we were promised that data science was going to be this incredible thing and create all this value for people. And I think nowadays it’s mostly viewed as a cost center in most companies. I think we can really now fulfill that original promise with agentic data science. Thomas Wiecki, Co-creator of

Agent-Harness.ipynb* May 20, 2026 4786 One thing that I don’t like about Claude is that you get into this weird mental state: oh, I think I trust the model. Let’s do the slot machine. Hit click, which puts you in an inactive mode of thinking.  Maybe it’s better to use a worse model….Vincent Warmerdam, senior data professional and prolific open-source maintainer (some packages with over a million downloads), now Engineer at marimo, join
Agentic Engineering and the Lost Art of Verification
Agentic Engineering and the Lost Art of Verification May 12, 2026 5546 > I almost don’t read code now. My approach with Roborev is it’s like my code reader. The mantra is: Roborev reads every line of code that is generated. It gets read multiple times. And so, whenever I push up a pull request, the branch gets re-reviewed. And so by the time I’m merging a pull request into a repository, the code has all been read by agents four or five times minimum. I look at the c
Next Level AI Evals for 2026
Next Level AI Evals for 2026 Apr 23, 2026 3214 There are a lot of reasons why we should do AI evals. For many companies doing AI evals is the way to build the feedback loop into the product development lifecycle. So it is like your compass. We’re using AI evals as a compass to guide product development and also product iteration. And also, many times we need evals to function as the pass or fail gate in release decisions. Whether this product

Privacy Theater Is Not Privacy Engineering: What It Actually Takes to Ship Safe AI Apr 15, 2026 3991 Katharine Jarmul, Privacy in ML/AI Expert & Author of Practical Data Privacy, joins Hugo to unpack why most AI privacy advice is theater: and what technical privacy actually looks like when you’re shipping LLMs, agents, and multimodal systems into the real world.In this episode, we dig into how to build defensible systems in an era of AI agents and multimodal models: why system prompts (and your
LLM Architecture in 2026: What You Need to Know with Sebastian Raschka
LLM Architecture in 2026: What You Need to Know with Sebastian Raschka Apr 13, 2026 4682 If you take a model release as an anchor point, let’s say Nemotron 3 or Qwen 3.5, you can go in both directions: You can either plug them into an agent and play around with that, or you can look, okay, what does the model look like under the hood? What are the ingredients? What type of attention mechanism do they use? What are currently research techniques that could make that even better in the n
Episode 72: Why Agents Solve the Wrong Problem (and What Data Scientists Do Instead)
Episode 72: Why Agents Solve the Wrong Problem (and What Data Scientists Do Instead) Mar 20, 2026 5619 I often see what I would consider to be b******t evals, especially in data, like write this dumb SQL. Almost every one of these dumb SQL questions that I’ve seen for benchmarks are just so either obviously easy or overwhelmingly adversarial. They just, they don’t feel valuable as a data scientist, it’s something that you probably would never ask a real data scientist to do. So I went out my way to
Episode 71: Durable Agents - How to Build AI Systems That Survive a Crash with Samuel Colvin
Episode 71: Durable Agents - How to Build AI Systems That Survive a Crash with Samuel Colvin Feb 18, 2026 3087 Our thesis is that AI is still just engineering… those people who tell us for fun and profit, that somehow AI is so, so profound, so new, so different from anything that’s gone before that it somehow eclipses the need for good engineering practice are wrong. We need that good engineering practice still, and for the most part, most things are not new. But there are some things that have become more
