I Gave My AI a Team. Here Is What Happened to the Expensive Work.
A plain-English look at how I split Codex work between an OpenAI lead and lower-cost OpenRouter specialists, what the evidence shows, and what it does not.
Rajeev Gill
I build practical software around AI, data, analytics, and adtech.
My work sits between product thinking and implementation, with a bias toward systems that make real work less messy.
Based in London. Interested in useful AI, clearer measurement, and software that holds up outside a demo.
