Insights on Workforce Engineering, AI spend management, and connecting engineering delivery to financial outcomes.https://www.flowstate.inc/enhttps://www.flowstate.inc/insights/will-hackett/buy-tokens-rent-gpus-or-own-the-rack/https://www.flowstate.inc/insights/will-hackett/buy-tokens-rent-gpus-or-own-the-rack/Open-weight models are now good enough to make self-hosting a financial question rather than a capability one. I modelled four options, an office rack, colocation, rented GPUs and per-token APIs, to find where each one actually wins. The answer turns on utilisation, and it isn't the one the internet keeps giving.

An intelligent proxy fixes both. Here is the maths, a calculator you can drag, and where Flowstate fits.

The findings line up closely with what we are seeing at Flowstate, from a different angle.

Here's the framework, the six practices, and how to get started.Sat, 11 Apr 2026 00:00:00 GMTWill Hacketthttps://www.flowstate.inc/insights/will-hackett/amortising-a-hallucination/https://www.flowstate.inc/insights/will-hackett/amortising-a-hallucination/We are currently adjusting our EBITDA to account for a sophisticated parrot that read the internet. Gartner says $2.52 trillion in global AI spend this year — yet only 14% of CFOs report clear ROI. Sequoia's 6:1 services-to-software ratio means the problem is about to get six times worse.

But the real shift isn't individual productivity—it's how engineering organisations allocate capacity across priorities.

What are you getting for it? Software engineering organisations struggle to answer basic questions about costs, and PE scrutiny is changing the game. It's more important now than ever to treat engineering like the investment it is.
