On the Principles of Agentic Engineering

This is a synthesis of ideas I’ve overheard, read, discussed, and learned first-hand. It draws on over three years exploring LLMs for shaping code. My initial notes for this were part of an internal workshop I hosted for our engineering team at TORTUS Health, where we use and improve these techniques every day as we work to eliminate error in medicine. The shifting bottlenecks With the explosion in LLM capabilities, producing syntax got cheap. But good judgement did not. In many ways, AI makes the easy part easier and the hard part harder. ...

On Vibecoding vs Agentic Engineering

We all use LLMs to make code, but there are at least two distinct modes of working with them. Both are powerful, but conflating them is dangerous. It leads to burnout, loss of agency, security breaches, and disastrous outages. Instead, we want to enable better ideas, executed faster, at higher quality.

Optimising cost, quality, latency

There is a trifecta of variables that just about everyone building generative AI systems cares about — cost, quality, and latency. As is often the case in computing, there is a trade-off between these properties. And all three are bought with the currency of performance.
