LLMs

Why intent and control are becoming the new software architecture

Watch now | Everyone’s talking about the Tamagotchi -- here’s what actually matters.

Credit: Museums Victoria / Unsplash There’s a lot of conversation right now about “context engineering” for dev work; structuring what you feed an LLM so it can do useful things. …

Large Language Models (LLMs) like OpenAI’s GPT-4 have transformed natural language processing, enabling applications ranging from chatbots…

A deep dive into effective caching strategies for building scalable and cost-efficient LLM applications, covering exact key vs. semantic caching, architectural patterns, and practical implementation tips.

In this article, you will learn how to add both exact-match and semantic inference caching to large language model applications to reduce latency and API costs at scale.

What is this job about really?

The goal of this page is to formalize my answer so that we can judiciously deal with patch requests produced by LLMs.

Implement a coding agent in 131 lines of Python code, and a search agent in 61 lines

AI coding agents burn 20-40% of their context window on codebase exploration. Structured documentation cuts orientation from 20 tool calls to 3.

AI's coding ability is outpacing our ability to wield it effectively. That gap closes in levels — 8 of them. Here's the progression from tab complete to autonomous agent teams.

No longer do we have anyone to question what you’re trying to accomplish.

New research from the University of Waterloo shows that artificial intelligence (AI) still struggles with some basic software development tasks, raising questions about how reliably AI systems can assist ...

The resolution of a human is much higher than we think

When speed matters more than perfection, API documentation can quickly become a bottleneck. In this post, I share how we used thoughtbot’s Claude Skill to generate Postman collections directly from a Rails codebase.

How I used Claude Code to build a GTD-based management system from a borrowed idea, meeting transcripts, and three days of real work.

Cursor Composer 2 delivers frontier coding benchmarks at a lower cost than its predecessor. A new cost-to-intelligence ratio for AI agents.

I once wrote an article with the optimistic title GitHub for the rest of us. The idea was that everyone who works with others on collections of shared documents needs a powerful and easy way to see…
