Constrained decoding solved a real problem. Before grammar-based methods like Outlines and SGLang, getting valid JSON from a language model was a retry loop.

The problem with point estimates When a machine learning model estimates the median value of a house in California, it usually hands you a single number: $385,000. That number may look precise.

Anyone can now build an LLM demo with a single API call. Getting that same feature to survive real users, real data, and a real bill is a different job.

A FAQ is already the answer, pre-written and paired with its question. Ask “What is my deductible?” and the right response is a lookup away: the support team wrote it, word for word, months ago.

For years, keeping a model healthy in production meant keeping it close to the model you shipped. You watch drift against a reference window. You track latency against an SLO.

There are so many positive sides that come with using systems like Claude; all the repetitive, routine coding gets automated, researching is quicker, and debugging becomes easier.

The user types “assurance décénale” and the document says “décennale.” One missing letter, and a literal search finds nothing.

A couple months ago I wrote about 3 Claude skills every data scientist needs to learn in 2026: - Claude Dashboards - Claude Cowork for prioritizing Jira tickets - Debugging with Claude Code.

The two frontier coding agents right now, by a long shot, are Claude and Codex; however, I have noticed significant differences in when the two models are superior, and I have noticed real...

A support request lands in the queue, and something has to work out what it is about before anyone can answer it. The hand goes to the prompt.

Three weeks after we put a text-to-SQL agent in front of our internal analytics team, someone asked it to "clean up the test rows in the promotions table."

When we ask Codex to complete a task, we usually think of it as a single agent. But if some tasks are complex enough and involve several distinct types of work, Codex will try to divide the problem...

In the first three articles of this series, I built a stateful LangGraph agent that handles a 15-minute booking process and wrapped it up with a Streamlit UI to improve user experience, and added a...

Have you ever asked Claude Code for a time estimate for implementing a feature? For example, you might be discussing a chatbot feature in your application and ask Claude: How long will this...

Welcome back! We recently discussed backpropagation, and I hope you now have an idea of what backpropagation is and how it actually works. Let's continue the deep learning journey.

Over the past few years, I am sure we all have witnessed and experienced a slow but significant change in the way we work.
