Pillar 3 - R&D efficiency & strategic partnership

Use two rows in "Pillar 3 - R&D efficiency & strategic partnership" to state the practical decision rules.

Step 1 of 2

The third pillar is where you stop being a cost reporter and become a thought partner. The job is to help senior leaders decide which experiments and investments are worth their GPU-hours - and to keep R&D spend from being confused with the cost of serving the product.

The first discipline is not conflating two very different kinds of spend. Production inference is COGS: the cost of delivering the product you already sell. R&D is investment: training runs and experiments that may or may not pay off. They are governed, budgeted and judged on different terms.

What it is
Production inference (COGS)
Compute to serve live users - tab, agent, completions
R&D spend (investment)
Training runs, evals, experiments, research
How it scales
Production inference (COGS)
With DAU and usage - more users, more cost
R&D spend (investment)
With ambition and bets, not directly with users
How it's judged
Production inference (COGS)
Gross margin and cost per active user
R&D spend (investment)
Expected value vs. cost and opportunity cost
The mistake
Production inference (COGS)
Letting it silently erode margin as you grow
R&D spend (investment)
Treating speculative bets as if they were fixed overhead

Conflating these two is one of the fastest ways to give a leader a misleading margin picture.
