Ready to join in on the fun?

Hi friends,

Our next AI for Engineers London Meetup is coming up on September 28! Join us for an evening of practical talks on AI engineering, where we'll explore how teams build, optimize, and experiment with modern AI systems—from making frontier models more affordable to the infrastructure behind coding agents.

Stop Paying for Frontier Models

Most of use reach for a frontier model by default and pay for it on every call, in latency, in energy, in cash, and in everything that leaves their stack. For most of those calls, a small local model would do the job.

RL Nabors, former Meta/React core team member and AWS alum, covers the vocabulary you need to reason about model performance (capability evals, golden datasets, LLM-as-judge) and walks through real cases: a local agentic harness replacing a frontier call, an in-browser moderation classifier defended with production-trace evals, and a generative summarization feature where the rubric turns out to be harder than the model. You'll leave with a framework for deciding when to choose large and off-prem or small and local models, and how to measure your way to the answer instead of guessing.

You will learn:

  • The vocabulary to reason about model performance (capability evals, golden datasets, LLM-as-judge).
  • A framework for deciding when a small or local model can replace a frontier one and when it can't.
  • A repeatable process for building capability evals from your own production traces, not someone else's benchmark.
  • Working examples of using eval results to iterate on prompts and ship with confidence instead of vibes.

Building a UI That Builds Itself

What if an AI agent could customize its own UI outside the chat and update it on the fly? As humans, some tasks that we work on are better done visually than in text format. That's why I started this experiment, where I give an agent a skill and teach it how to work in a highly visual workspace it can extend and update with custom UIs. I'll walk you through how we designed a skill, a CLI, and a front-end app that work in tandem to make it possible. How we spent weeks figuring out the best and most minimal design system an agent can use to generate "slop-free" designs. The project is completely open-sourced and available on https://moi.computer/
